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. Read more exciting novels for free

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>
Can an 8-bit single-chip computer be used as an electric tool?
Single-chip computers could be used in the industrial field, while electric tools belonged to the industrial category. The 8-bit single-chip computer was a single-chip computer with an internal arithmetic unit that could process 8-bit binaries at a time. It could perform operations such as addition, reduction, multiplication, and division. The internal register was mostly 8-bit, so it could be regarded as a weak micro-computer system. Theoretically, an 8-bit single-chip processor could be used to develop and control functions related to power tools, but the specific application depended on the complexity of the power tool's function development. If the power tool needed to develop a simple function, an 8-bit single-chip processor might meet the demand. If more functions were needed, a single-chip processor with a higher number of digits might be needed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Will the power supply of the single-chip computer board burn out if it is short-circuited?
When the power supply of the single-chip computer board was short-circuited, it might burn the single-chip computer. If 3.3V and gnd were short-circuited, the tester would detect a buzzing sound. This did not necessarily mean a short-circuit, but it was possible. There were many condensers, microcontrollers, and possible interface chips between 3.3V and gnd. Any short circuit would cause a short circuit between 3.3V and gnd. During the inspection, the 3.3V related to the chip can be removed and measured again to see if the chip is short-circuited. If it is short-circuited, the chip can be disassembled to measure the resistance between the chip's 3.3V and the ground. You can also measure the voltage of the microchip by welding one of the feet of the microchip's voltage. If the voltage is still connected to the voltage, the microchip may be damaged. In this case, the microchip may need to be replaced. If you are using the smallest system board such as the K60, you can change your own single-chip computer or send it back to the manufacturer for replacement. In addition, pay attention to static electricity protection during welding, otherwise static electricity may break through the chip and cause damage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
