This picture shows that the working frequency is not low. Here are some pictures for you to see: 1. A close-up of a single tube (LOG for yourself)2. Close-up of two tubes (combined circuit)3. Using Al...
I have a new 5402 board. I can enter CCS when connected to a USB emulator, but I can't download. When I download, it reports an error saying that the connection with the emulator is disconnected. I ca...
I saw an activity on Sohu, saying that as long as you say that you have passed on the idea of LePhone, you can get a LePhone to try, and the LePhone will belong to you~ But the conditions for winning ...

Chip: STM32F107VCT6 Application Pin: THOUSANDS, RMII STM32CubeMX is very convenient to use ETH. The software comes with LWIP and configuration. This time, STM32F107VCT6+DP83848CVV is used. The MII a...[Details]
This is my first time writing an STM32 program. I have many questions to ask. I want to convert the data of the SO of MAX6675 into the actual temperature and read it out using the serial port tool. I...[Details]
In most countries, the military is a fairly large group, and the health of soldiers is particularly important to the combat effectiveness of the army. The US Department of Defense's Advanced Resear...[Details]
In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[Details]
sprintf is a function in the C language library that converts data types. There is a situation where In 51 MCU, define unsigned char temp; Then I want to use the serial port to print out temp in deci...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
Summary of STM32 peripheral DMA usage: 1. Select DAM mode according to your needs: (1) Circular mode—DMA_Mode = DMA_Mode_Circular (2) Normal mode—DMA_Mode = DMA_Mode_Normal 2. For Chanel3 of DMA1, t...[Details]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
The single-chip microcomputer running light program requires all 32 serial ports to be used, and each serial port has eight LEDs. Question supplement: The 8051 single-chip microcomputer is used, an...[Details]
