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>
What is the principle of the single-phase half-wave controllable rectify circuit simulation experiment?
The single-phase half-wave controllable rectify circuit was mainly composed of a transformer, a crystal-controlled reactor, and a load resistance. When conducting simulation experiments, the principle was as follows: 1. * * Analysis of the switching state of the thyratron ** - In the positive half-wave of the power supply voltage (0-Pi interval), the thyratron bears the forward voltage, but before the pulse u_G triggers the thyratron at the control angle, the thyratron is turned off. At this time, there is no current flowing in the load r, the output voltage u_d is 0, and the voltage the thyratron bears is the power supply voltage u_{ZT}= u2. - When the thyratron is triggered at <<Omega>=<Alpha>>, the thyratron will start to conduct, forming a load current <i_d>>. There is an output voltage and current on the load. At this time, if the tube voltage drop is ignored, the voltage across the load is the secondary voltage of the transformer <u_2>>, and the wave form of the load current <i_L>> is similar to the wave form of <u_L>>. - At the moment of <<Omega>>, the power supply voltage naturally crosses zero, and the cascaded current is turned off when it is less than the sustaining current. The load current is zero. - In the negative half-wave of the power supply voltage (in the range of <Pi>-2<Pi>), the thyristors are in the off-state due to the reverse voltage. There is no output voltage on the load, and the load current is zero. 2. * * Effect of control angle and conducting angle on output ** - The electrical angle from the moment the controllable silicon begins to withstand the forward voltage to the time when the trigger is turned on is called the control angle. The electrical angle of the controllable silicon in a cycle is called the conducting angle. In a single-phase half-wave rectify circuit, the smaller the control angle, the larger the conducting angle, and the larger the average value of the load voltage and current. By changing the size of the control angle, the output voltage can be changed to achieve the purpose of voltage regulation. 3. * * Piecewise-linear Circuit Analysis ** - Using the switching characteristic of the thyratron, the non-linear circuit was transformed into a piecewise-linear circuit. In different intervals (such as the turn-off and turn-on stages of the thyratron), the circuit presented different linear characteristics, so the existing circuit theory could be used to analyze each stage separately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single-phase half-controlled rectify circuit-
In a single-phase half-controlled rectify circuit, the electrical angle at which the crystallizer is in the on-state during a power cycle is called the conducting angle. The electrical angle from the moment the thyratron starts to bear the positive voltage until the trigger pulse is applied is called the trigger delay angle (trigger angle or control angle). By changing the trigger time, the voltage and current waves of the rectified voltage can be changed accordingly, and the output voltage of the direct current is a pulsating direct current with the same pole but the instantaneous value changes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Reason for the Damage of the Single-Chip Microprocessor
In a three-phase induction motor, many of the motor's damage is due to the electrical system, which may lead to the burning of the winding. The details are as follows: 1. The insulation of the motor is reduced; 2. The motor runs without phase; 3. The motor was overloaded. 4. Poor ventilation of the motor caused the temperature to be too high; 5. When the knife switch was used as the load switch, the motor was burned due to the power failure and forgetting to pull the brake. 6. Overvoltage or undervoltage operation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Development of Single-Chip Computer Scale
The following are the general steps and key points of the development of the single-chip electronic scale: ** 1. Hardwares ** 1. ** Main control chip selection ** - He could choose a more common chip like the 8051 single-chip computer. It had 4KB of internal program memory (Scalable), 128-Byte internal data memory (Scalable), multiple bi-directional parallel input/output ports, and other resources to meet the basic control and data processing needs of the electronic scale. - It also has the advantages of low working voltage, low power consumption, strong driving ability, etc. For example, its I/O port is bi-directional and the output circuit is a complementary push-pull output circuit. The external circuit is simple in driving the digital tube display, and its A/D is 10 bits to meet certain precision requirements. 2. ** Sensing and signal processing ** - The sensor was used to obtain physical quantities such as weight. For example, using a pressure sensor to detect the weight of an object usually required a special signal processing chip, such as the HX711 for processing pressure signals (range 0 - 5kg, accuracy 0.1 g). 3. ** display module ** - The 1602 LCD module was used to display the date, time, weight and other information. It was necessary to connect the single-chip computer to the 1602 liquid crystal, including the connection of the data port and the control port. The software programming was also used to initiate and write data into the 1602 liquid crystal. 4. ** Clock module (option)** - If you need to record time-related information, you can use the DS1302 clock chip. It could provide accurate date and time information for the electronic scale. The microchip needed to communicate with it through the corresponding interface circuit to read and set the time. 5. ** Communication module (option)** - If you want to upload the data to the PC display, you can use the 232 serial communication. The single-chip computer had to set up the serial port, including the configuration of baudrate, data bit, stop bit, and other parameters to achieve stable data transmission with the PC. 6. ** Power Circuit ** - It provided a stable power source for the entire system. It was necessary to design a suitable power supply circuit according to the voltage requirements of the selected chip and other electronic components. For example, a voltage stabilizing chip was used to convert the input voltage to a stable 5V or 3.3V voltage to meet the power supply requirements of the single-chip computer, sensor, display module, etc. ** 2. Software ** 1. ** Selection of programming language ** - If you use the 8051 single-chip computer, you can generally use assembly language or C language for programming. For beginners, C language was relatively easier to understand and write complex program logic. - For the PIC-based single-chip computer, you can also use the C language or its specific programming language, but you should pay attention to the differences between the 8051 single-chip computer and the 8051 single-chip computer in terms of instruction set and register usage. 2. ** Program Function Realization ** - ** Initialize settings **: Initialize the ports, timers, and interrupt of the single-chip computer. For example, set the port connected to the sensor to the input mode and the port connected to the display module to the output mode; Initialize the timer to meet the timing requirements (if there is a timing function requirement); Configure the interrupt (if the interrupt is needed to process the sensor data collection or other events). - ** Data Collection **: Obtain weight and other data from the sensor through programming. If the HX711 was used to process the pressure signal, it was necessary to read the processed pressure data (weight data) from the HX711 according to the communication protocol of the HX711 and convert it into an actual weight value. - ** Data processing **: To process the collected data, such as filtering to reduce errors caused by sensor noise. Simple arithmetic average filtering or other filtering algorithms can be used. - ** Show Function **: Show the processed weight, date, time and other data on the 1602 LCD. This required writing the corresponding display function according to the display specifications of the 1602 liquid crystal, converting the data into a format suitable for display and sending it to the liquid crystal display module. - ** Communication function (option)**: If there is a serial communication function, write a serial communication program to send the data to the PC in the agreed format. This included the packaging and verification of the serial port data to ensure the accuracy of the data transmission. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single chip voltage simulation software
There were some software that could be used to simulate the voltage of the single-chip computer, such as the Simuide, which could not only simulate the circuit but also simulate the AVR single-chip computer. The windows version had the built-in tuning software for the pid single-chip computer. Due to the GPL agreement, the debuggers for the linux-based version needed to be installed. It integrated the Arduino compilation and tuning environment, and the Arduino code could be written and run on it. There were a variety of electronic components in the software that could be freely used. Probes and voltage meters could be added anywhere in the circuit simulation circuit. An ammeter or an earpiece could be used to monitor the voltage and other changes. It could also monitor the memory and register of the single-chip computer. There was also the Proteus software, which was excellent in the simulation of single-chip processors. It supported the simulation of 8051, PAC, and AVR single-chip processors. It could carry out circuit design, circuit board layout and design, circuit simulation parameters analysis, and also support the analysis of various circuit parameters such as voltage. It could also visualize the simulation data through various charts and graphs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Discussion and conclusion of single-tube AC amplifier circuit
The related conclusions and discussion of the single-tube AC amplifier circuit are as follows: * * 1. In terms of static work points ** 1. * * Important ** - The setting and adjustment of the static working point was crucial. A reasonable setting can make the amplifier work stably and reliable. To obtain the maximum undistorted voltage, the static operating point should be located at the middle of the AC load line. In order to stabilize the operating point, certain conditions must be met, such as <BQ>> II <I21>. 2. * * Calculation Method ** - The static operating point can be calculated by a specific formula, such as <R = U21UU> II>, or <<CBBBQE + RR1EBEQBQEQCQR-CQCCQR>-UE= I <EcCQCreERCCEQ + RR-I = E-U-U = EUbeI = ICQBQ>. The calculation involved the parameters of various components in the circuit, such as the base power supply, bias resistance, collector power supply, collector resistance, etc. These components interacted to determine the state of the static operating point. - The static working point can be measured with the Model MT-47 Multimeter. * * 2. Dynamic parameters ** 1. * * Calculation of voltage amplification and input and output resistance ** - The voltage amplification factor is related to the input and output resistance calculation, and the calculation result is usually affected by certain conditions (such as <26> 1>(IEQHR = 0>). - The input resistance, r_{i}, has the following values: r_{i}= R_times beLiouru = A '-_, and because of the two values, we have the following values: LcL//R = RR'_, beBBBi21BBbeR <<Rr_, so we have the following values: beirR =_, and mVMV +_beta += rr' bbbe_, where Omega = r'bb300c_. The input resistance can also be calculated by using [sisiR-uuu]. - The output resistance, r_{o}, can be calculated by the formula, where, u is the output voltage at no-load, and u0 is the output voltage at load. The calculation of the output resistance is related to factors such as the load resistance in the circuit. When all the excitations are assumed to be zero, the controlled source is cut off, and the output resistance can be calculated accordingly. 3. * * Impact on circuit performance ** - The variation of circuit parameters will affect the static operating point, voltage amplification and output wave. For example, when an AC signal was input, the circuit only had a static operating point when the direct current passed through it. The AC signal would interact with the static direct current, affecting the voltage and current at each point in the circuit, which in turn affected the amplification factor and output wave. For example, in a circuit consisting of a mos tube and a semiconductor, the positive and negative half cycles of the AC signal would change the working state of the mos tube and the semiconductor, thus affecting the amplification performance and output characteristics of the entire circuit. - In the experiment, you can change the component parameters in the circuit (such as R_{C}, R_{L}, etc.) to observe and measure the impact on the static operating point, voltage amplification, and output wave. This helps to understand the working principle and characteristics of the single-tube AC amplifier circuit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
