Single-Chip Computer Spectral Circuit Design Experiment Report
The following is an example of a single-chip frequency circuit design experiment report: ** 1. Purpose of the experiment ** The purpose of this experiment is to design a spectrum circuit based on a single-chip computer, to realize the analysis and display of the input signal spectrum characteristics, to master the application principle of single-chip computer in spectrum analysis, as well as the design and tuning methods of related circuits. ** 2. Experiment Principle ** 1. ** Basics of Spectral Analysis ** - Spectral analysis was a technique that converted a time-domain signal into a frequency-domain signal to obtain information such as the frequency composition and magnitude of the signal. For a complex periodic signal, it could be decomposed into a series of sinewaves of different frequencies. - In this design, the input signal was processed by a specific circuit module, and then the processed signal was collected and analyzed by the single-chip computer, and finally the frequency spectrum information of the signal was obtained. 2. ** The role of the single-chip processor in the frequency spectrum circuit ** - The single-chip computer was the core of the control system and was responsible for coordinating the work of each circuit module. For example, control the collection of signals, the execution of processing algorithms, and the display of spectrum results. - Choose the appropriate model of the single-chip (such as the STM32F103 single-chip, etc.), which has sufficient processing power, appropriate I/O interface, and rich internal resources (such as timers, ADC, etc.) to meet the design requirements of the spectrum circuit. 3. ** Circuit module composition ** - ** Program Controlled Attenuation module **: For example, the HMC624 and other program controlled Attenuation modules are used to adjust the amplitude of the input signal to adapt to the input range requirements of the subsequent circuit modules. This was because the magnitude of the input signal might vary greatly, and it needed to be weakened to a suitable range to prevent the signal from being saturated or damaging the subsequent circuits. - ** filtering module **: filtering the input signal through a filter to remove unwanted frequency components or noise. According to the design requirements, different types of filter such as low-pass, high-pass, band-pass, or band-stop filter can be selected. - ** Mix module **: Like the ADL5801 Mix module, it will mix the input signal with the signal generated by the local oscillation, and convert the high frequency signal into an intermediate frequency signal. This helped to reduce the frequency of the signal, making it easier for subsequent processing and analysis. - ** Fixed gain amplifier module **: For example, the ADL5611 fixed gain amplifier module can amplify the intermediate-frequency signal after mixing to increase the signal amplitude and meet the requirements of detection and ADC acquisition. - ** Detector module **: The ADC 8310 detector module is used to detect the amplified intermediate frequency signal and convert the AC signal into a direct current signal so that the ADC of the single-chip computer can collect it. - ** Phase-locked loop chip (such as ADF4351)**: It is used to generate the system sweep frequency signal generator to generate a stable local oscillation signal. The output signal frequency range can be set according to the design requirements (such as 35 to 400MHZ). ** 3. Experimental Equipment ** 1. Single-chip development board (including the selected single-chip, such as STM32F103 development board). 2. The circuit modules included a program controlled decay module, a filter module, a frequency mixing module, a fixed gain amplifier module, and a detector module. 3. [Oscillograph: Used to observe the input signal, intermediate signal, and output signal's wave forms, and assist in circuit tuning.] 4. Signal generator: provides input test signals of different frequencies and amplitude. 5. Power supply: provides a stable supply voltage for the entire spectrum circuit. 6. Other auxiliary components, such as resistance, capacity, induction, etc., were used for circuit connection and signal matching. ** 4. Experimental Steps ** 1. ** Circuit Connection ** - According to the circuit diagram, connect each circuit module to the single-chip development board. First, connect the power circuit to ensure that each module is supplied with the appropriate power supply voltage. - Connecting the input and output ports of the program control decay module, connecting the input signal to the program control decay module, and connecting the decayed signal to the filtering module, the frequency mixing module, the fixed gain amplifying module, and the detection module in turn. - The output of the detector module was connected to the ADC pin of the single-chip computer so that the single-chip computer could collect the detected direct current signal. - It is connected to the phase-locked loop chip to provide the local oscillation signal for the mixing module. - The I/O interface of the single-chip computer was used to connect the control signal to the control pins of each circuit module, such as the control pin of the program controlled decay module, the control pin of the phase-locked loop chip, etc. 2. ** Single-chip programming ** - Initialize the system clock, ADC, timer, and other internal resources of the single-chip computer. - Write a program to realize the control logic of the program control decay module, phase-locked loop chip, etc. For example, through the I/O port of the single-chip computer to output control signals, set the decay value of the program controlled decay module, the output frequency of the phase-locked loop chip, and so on. - Write the ADC acquisition program, and set the ADC's parameters such as the frequency and resolution to collect the detected direct current signal. - Realizing the spectrum analysis algorithm. A Fast FT Transform (FFT) algorithm can be used to convert the collected time domain signal into a frequency domain signal to obtain the frequency spectrum information of the signal. - Write a display program to display the spectrum information in a suitable way. For example, a LCD screen could be used to display information such as frequency and spectrum. 3. ** Circuit Testing ** - Observe the input signal's wave form with an earpiece and check whether the frequency and amplitude of the signal meet the design requirements. - After the circuit connection was completed, he gradually powered up each circuit module and observed the output signal wave of each module. For example, observe the filtering effect of the output signal of the filtering module, whether the intermediate frequency signal output by the mixing module is correct, and so on. - To ensure the accuracy of the program, the program could be debugged using a serial port or other means to check the variable values and program execution process during the program operation. - He adjusted the parameters such as the decay value of the programmed decay module and the output frequency of the phase-locked loop chip, observed the changes in the frequency spectrum results, and optimized the performance of the circuit and program. ** 5. Experimental results and analysis ** 1. ** Spectral result displayed ** - Through the LCD screen or other display devices, the frequency spectrum of the input signal was successfully displayed. The frequency spectrum could clearly reflect the frequency components of the signal and its magnitude relationship. For example, for an input signal synthesized by multiple sinewaves of different frequencies, the frequency spectrum could accurately display the frequency peak and the magnitude of each sinewave. 2. ** Accuracy of frequency measurement ** - The accuracy of the measurement of the frequency of the signal by the frequency spectrum circuit was measured by comparing it with the known frequency signal output by the signal generator. The experimental results showed that within a certain frequency range, the spectrum circuit could accurately measure the frequency of the signal, and the error was within an acceptable range (for example, the error was less than 5%). 3. ** Amplitude measurement accuracy ** - Comparing the input signal with a known amplitude, the accuracy of the signal amplitude measurement by the spectrum circuit was analyzed. Due to the influence of various noise and non-linear factors in the circuit, there may be some errors in the amplitude measurement. Through the analysis of the experimental data, it was found that the amplitude measurement error mainly came from the gain error of the programmed decay module, the amplifier module, and the non-linear detector module. ** 6. Experiment summary ** 1. This experiment successfully designed and implemented a frequency spectrum circuit based on a single-chip computer, which could analyze the input signal and display the spectrum results. 2. During the experiment, problems such as circuit connection errors, single-chip program logic errors, signal interference, etc. were encountered. Through careful circuit inspection, program tuning, and some anti-interference measures (such as reasonable wires, adding filter magnets, etc.), these problems were finally solved. 3. The experimental results showed that the frequency measurement and the amplitude measurement were accurate, but there were also some sources of error. In the subsequent improvements, the performance of the spectrum circuit could be improved by selecting higher-precision circuit modules and optimization algorithms. 4. Through this experiment, the core control function of the single-chip computer in the spectrum circuit and the basic principle and implementation method of the spectrum analysis were deeply understood, which laid the foundation for the further development of related electronic circuit design and research.

Design of led display interface circuit for single-chip computer
There are many ways to design the single-chip LED display interface circuit. The following are the common points: ** 1. Parallel port display ** 1. ** Resource Usage ** - This method would take up a lot of port resources of the single-chip computer. However, using chips like the 8279 could achieve dynamic display, so it was relatively easy to write programs. However, it was not recommended for designs where the parallel port of the single-chip needed to connect to many devices, because it would exhaust the parallel port resources. 2. ** Principle example ** - For example, in some designs, if the C2051 single-chip computer was used, the cheap and easily available 74LS164 and 74LS138 could be used as expansion chips. The 74LS164 is an 8-bit serial-in and serial-out shift register. It can decode the serial data output from the C2051 serial communication port and output it on its parallel port line to drive the LED digital tube. The 74LS138 was a 3 - 8 decode that would decode the address signal from the single-chip processor and drive the corresponding LED. Due to the low current drive capability of the 74LS138, the final driver 2SA1015 was sometimes used as the address driver. The segments of the four LED were connected together, and their public end was gated by 74LS138 to achieve a dynamic scanning display mode. ** 2. The serial port is displayed ** 1. ** Resource utilization advantage ** - When the number of parallel I/O ports of the single-chip computer is limited and needs to be used for other more important purposes, you can consider using the serial port display. For example, the serial communication port of the 80C51 was a powerful and easy to use communication port that could be used for display driver circuits. With two serial communication port lines and two ordinary I/O ports, a 4-bit LED display circuit could be designed; with two I/O port lines, an 8-bit LED display circuit could be easily realized. 2. ** Program Writing Characteristics ** - When using the serial port for LED communication, the programming was quite simple. The user only needed to send the data to be displayed directly to the serial port sending buffer and wait for the serial interrupt. ** 3. Digital Tubes ** 1. ** Principle of display ** - The LED digital display was a display device that used a combination of LED light emitting devices to display characters. Usually, eight LED light emitting devices were used, of which seven were used to display characters and one was used to display the decimal point. It was called a 7-segment (also known as an 8-segment) LED digital display. In order to display the characters, the LED display had to be provided with a display segment code (or glyph code). The corresponding relationship between the code positions of each segment was related to the seven segments that formed the "8" character and the decimal point. 2. ** Connection Method ** - The LED digital display had a common positive pole connection method. ** 4. Other considerations ** 1. ** Current limiting resistance ** - The resistance in the circuit played a role in limiting the current, which was used to reduce the current flowing through the LED to prevent damage to the LED lamp. Take the red chip LED as an example, its working voltage range is 1.6V to 2.4V. If the power supply voltage is 5V, the appropriate series resistance should be calculated according to Ohm's law. For example, the voltage across the resistance is the power supply voltage minus the LED voltage drop (5 - 1.8 = 3.2V), and then the resistance value is calculated according to the expected current value (Assuming that the current through the LED is 3.2mA, the resistance value is 3.2V/3.2mA = 1k Omega). 2. ** Pull-up Resistors (if involved)** - The choice of the pull up resistance needed to balance power consumption, driving ability, and circuit speed. In order to reduce power consumption and chip sink current, the resistance value should be as large as possible; in order to ensure sufficient drive current, the resistance value should be as small as possible; in high-speed circuits, too large a pull up resistance may cause the signal edge to become smooth. Usually, the value of the pull up resistance is selected between 1k Omega and 10k Omega. 3. ** Filter-filter (if involved)** - There were two types of filter condensers: high frequency and low frequency. The high-frequency filter usually uses a 0.1 microF filter, which is used to short-circuit high-frequency noise and protect the circuit from interference. The low-frequency filter usually uses a 100 microF aluminum filter, which is used to filter out low-frequency ripples and stabilize the power supply. These are usually installed next to the power interface or high-power components, such as USB interface or stepping motor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
single-chip computer subdividing circuit
Microchip micro-circuits have an important application in the control of stepping motor. Taking the two-phase hybrid stepping motor as an example, its subdivision circuit can be constructed by combining integrated chips and separate components, such as the two-phase hybrid stepping motor's self-adapting subdivision drive circuit designed based on the AT89C51 single-chip computer. In the step motor fine control, the fine division technology was a kind of electronic damp technology. The purpose was to improve the operation accuracy of the motor and achieve high-precision fine division of the step angle. For example, in the driving state of two phases and four beats, when the control system does not subdivide, each step pulse motor will rotate an inherent step angle (such as 10°), and when the subdividing driver works in the 10 subdividing state, the motor will only rotate 1°. The subdividing function was achieved by the driver or the single-chip processor by precisely controlling the phase current of the motor, and had nothing to do with the motor itself. There were many factors to consider when constructing a single-chip circuit: 1. ** Power supply related **: Make clear the differences between the labels of different power supplies, such as VRCs, VRCs, and VSSs. For example, VRCs are usually the power supply voltage of a Bipolar device. In an NPM circuit, it represents the power supply voltage connected to the collector. In a field effect circuit, it represents the power supply voltage connected to the drain. In a PPM circuit, it represents the power supply voltage connected to the transmitter. In a circuit with a PPM circuit, it represents the power supply ground or 0V, which is the reference point of the circuit. 2. ** Resistance selection **: - ** Pull-up Resistor **: The choice of the pull-up resistance needs to balance power consumption, driving ability, and circuit speed. In order to reduce power consumption and chip sink current, the resistance value should be as large as possible; in order to ensure sufficient drive current, the resistance value should be as small as possible; in high-speed circuits, an excessively large pull up resistance may make the signal edge smooth, usually between 1k Omega and 10k Omega. In the reset circuit, the resistance value is critical to the start-up of the single-chip computer. For example, when R1 = 10k Omega, it may cause the SSR pin to show a high level, causing the single-chip computer to continue to reset and not work normally. - ** Current limiting resistance **: For example, in an LED circuit, the current limiting resistance should be calculated according to the operating voltage, current range, and circuit voltage of the LED. If the power of the current limiting resistance is not selected properly, there may be problems. For example, in a circuit with an LED voltage drop of 3V, a total voltage of 96V, and a current limiting resistance of 5.1 Ohms, the calculated current is 18ma. However, if the current limiting resistance is 1206, the rated power is 0.25W, and the actual power is 1.7W, the circuit will have problems. 3. ** Condenser application **: There are two types of filter condensers: high frequency and low frequency. The high-frequency filter (usually 0.1 microF) is used to short-circuit the high-frequency noise protection circuit; the low-frequency filter (usually 100 microF) is used to filter out the low-frequency ripple and stabilize the power supply. It is usually installed next to the power interface or high-power components. 4. ** Usage of other components **: - ** Triode **: It has a variety of functions, such as switching function (by controlling the base current to switch between on and off), amplifying function (can amplify the base current by 100 times to drive a larger load), and level conversion function (used for communication between different levels). - ** Nixie tube **: By controlling the seven segments of A - G and the decimal point, it displays the number. It requires a matrix and a truth table to control the brightness of each segment to correspond to a specific number. - ** Key vibration treatment **: The operation of keys will cause vibration, which can be eliminated by software (delay 5 - 10ms after detecting the closed key and wait for the vibration to disappear before confirming the key state) or hardware (use the short-circuit effect of the high-frequency signal by the capacity). When the single-chip I/O port is not enough, the number of ports can be increased by expanding the chip such as the 74HC13838 translator to meet the design requirements of the subdivision circuit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Crystal Circuit of 51 Single-Chip Computer
In the 51-bit single-chip computer, the crystal circuit was a crucial part of the peripheral circuit of the single-chip computer. From the perspective of pin connection, the 51 single-chip computer had two pins, XTAL1 and XTAL2, for connecting to the crystal oscillation (crystal resonant). These two pins were connected to an internal phase shifter of the MCUs to form a Pierce Oscillator with the external crystal oscillation. The working principle was that the Pierce Oscillator needed to meet the two conditions of 2k Pi loop phase shift and closed-loop gain of 1 in the ideal circuit form. The phase shifter provides a 180° phase shift for any frequency component and can be seen as a buffer. It is easy to obtain a loop gain of 1 by adjusting its output characteristics. However, this was not enough to start the vibration. The crystal itself was very important. Quartz crystals had a piezo electric effect. After processing, the Quartz Crystal Resonator (QCPR) could be represented by an ideal circuit model consisting of a L1 - C1 - R1 series resonant circuit plus a very small C0. The QPR was connected in parallel with the phase shifter to act as a frequency selection network. When it was powered on, it could be seen as a step signal being input into the output of the phase shifter. The QPR picked out the signal at the resonance point frequency. When the loop gain was 1, the circuit tended to be stable. In the crystal circuit, the common crystal frequencies were 4, 8, 11.0592, 12, etc. The crystal was used to provide a stable clock signal for the single-chip computer. All the instructions of the single-chip computer were based on this. The speed of the single-chip processor was related to the clock frequency provided by the crystal. The higher the clock frequency, the faster the single-chip processor would run. From the composition of the crystal circuit, it was composed of a Quartz crystal and a circuit. Together with the reset circuit, it ensured the stable operation of the single-chip system. The main function of the crystal circuit was to provide clock signals for the operation of various modules within the single-chip computer to ensure the correct execution of the program. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Simulation circuit diagram of the single-chip computer
The following are several examples of simulation circuits related to single-chip processors: - In the ESP32 and Arduino single-chip simulation (such as the website of the website, the simulation circuit that lights up the LED light needs to add an LED light and a current limiting resistance. The negative pole of the LED lamp was connected to the GND pin of the single-chip development board, the positive pole was connected in series with the current limiting resistance, and the other end of the current limiting resistance was connected to the No. 2 pin of the development board. - For the simulation circuit of the steering gear control, add the steering gear in the hardware circuit (the steering gear has three pins, namely, the voltage regulator, the voltage regulator, and the voltage regulator. The voltage regulator is connected to the negative pole of the power supply, and the voltage regulator is connected to the positive pole of the power supply). Then, connect the steering gear to the single-chip computer (if you use the Arduino single-chip computer, you can choose a pin with a "~" to output the voltage regulator signal. In this project, pin 3 is selected as the voltage regulator output pin). - If the simulation uses L298 to drive the direct current motor, the circuit includes the L298N chip (this is a dedicated driver integrated circuit, belonging to the H bridge integrated circuit), the display part uses the PG 160128A (the liquid crystal display dot matrix is 160X128), the input device is a 4X4 matrix keyboard, and it may also include measurement tools such as a virtual scope. The positive and negative rotation of the motor can be controlled by the P1.0 pin of the single-chip computer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

stm32 single-chip computer USB download program circuit
There were two ways to download the STM32 program. One was based on JTAG (SWD). This method required an simulator (such as J-Link and U-Link) to efficiently and quickly debugged the STM32 single-chip system. The other was based on serial port. The entire STM32 series supported this method. This method could download the HEX file to the STM32 chip through a USB cable and the corresponding ISP download software. In order to download the circuit through the serial port, one must first understand the several boot modes of the STM32. If you want to download the code through the serial port, you need to set BOOT0 to 1 and BOOT1 to 0. If you want the STM32 to run the code as soon as it is reset, you need to set BOOT0 to 0 and BOOT1 to any value. A circuit could be designed to control the one-button download circuit through the serial port to USB chip CH340G's DTL #and RTS#pin signals, thereby indirectly controlling the STM32's RESET and BOOT0 pin signals, achieving the effect of one-button download and operation through the serial port. The serial port download software can choose MCUSP, which can automatically allocate the BOOT0 and RESET signals through the DTL and RTS signals of the serial port. The user does not need to manually switch the state. Open MCUIsp, click Search serial port, and it will automatically find the onboard serial port of the circuit board. Choose the baudrate of 460800 in the bit rate, select the low level reset of DTL in the lower left corner, and then load the burn file into BootLoader at RTS high level. Before the program was written, click to read the device information. If the relevant information appeared, it meant that the serial port connection of the circuit board was successful. Then click to start programming, and the program began to be written. After the program was successfully written, a message indicating that the program was successfully written would appear. The specific process was as follows: mcuisp controls the DTL output to be low, so DTL #output is high. Then RTS is set to high, so RTS#output is low, so Q3 is turned on and BOOT0 is pulled high. At the same time, Q2 will also be turned on, and the reset pin of STM32 will be pulled low to achieve a reset. Then, after a delay of 100ms, mcuisp controls DTL to be at high level, DTL #will output low level, RTS will remain at high level, RTS#will continue to be at low level. At this time, the reset pin of STM32 will become high level because Q2 is no longer connected. STM32 will end the reset, but BOOT0 will still remain at 1, thus entering the SP mode. Then mcuisp can start to connect to STM32 and download the code, thus realizing one-click download. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Single-Chip Coupled Circuit Diagram
As for the single-chip coupled circuit, in some electrical control products, the input circuit part involved coupling-related content. For example, when the various control signals of traditional electrical equipment are converted into digital signals that match the input/output port of the single-chip computer, the control signals input by the user equipment to the single-chip computer (such as the switch output of the limit switch, the operation button, etc.) are converted through the input circuit, where the input circuit has a coupling-related function. There was also the circuit diagram of the optical coupler-driven relay in the circuit of the single-chip drive relay. The optical coupler-driven relay played a role in the circuit, but the specific circuit diagram needed to be consulted in special documents, such as the circuit diagram of the optical coupler-driven relay (optical coupler/UL2803/switch circuit) and other related information. In addition, the document on the design method of the commonly used drive and coupled circuit of the single-chip I/O for the characteristics of electrical control products may have more detailed design content about the single-chip coupled circuit, but it did not directly give a detailed circuit diagram. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Introduction to Computer Experiment Report
The experience of an introductory computer experiment report usually contained a variety of content. In terms of gaining knowledge and skills, one would realize the importance of combining theory and practice. For example, in the past, one might think that one's theoretical knowledge was enough, but in practice, one would find many problems. For example, when writing a program, even if it was a program copied from a textbook, there might be many errors in actual testing. This showed that practice was the key to testing the mastery of knowledge. Only through a large number of computer operations could one truly master the relevant knowledge in the introduction to computer science. From the perspective of the course content, through the computer introduction experiment, you can understand things like numerical values and coding.(The conversion between the binaries, octals, decimals, and hex, the representation of the original code, complement code, and code shift, the representation of fixed-point numbers and floating-point numbers, etc.), arithmetic operations and logical operations (fixed-point addition, multiplication, and division, floating-point operations, and logic operations, etc.), as well as the arithmetic logic unit (the function and structure of the ALU, etc.). At the same time, in terms of overall quality improvement, it helped to improve independent thinking and hands-on ability. When working on projects or solving problems in experiments, one needed to rely on oneself to think of solutions, manually debugged code, and so on. This was a good exercise for one's self-ability. Moreover, it could also enhance the ability of teamwork. During the experiment process, it might be necessary to cooperate with classmates to complete tasks together, so as to realize the importance of teamwork in computer related projects. In terms of the impact on future studies and career development, computer science introductory experiments could make people clear their direction in professional knowledge learning. If he found that he had difficulty understanding and operating a certain piece of knowledge during the experiment, he could strengthen it in the subsequent learning. Moreover, this kind of experimental experience could also make people realize the requirements of the computer science profession in real work, and encourage them to constantly improve to adapt to the needs of society.
