In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]

The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]

In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]

In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]

    With the development of information technology, intelligence, informatization and networking have become the development trend of modern industrial control. Since the 1980s, the rapid development...[Details]

I used the bit definition in my 51 program: bit flag. After defining it this way, I ran the program and downloaded it to the circuit board. I found that the flag was not the value I set, which led to...[Details]

The Vatican Secret Archives is one of the world's greatest historical collections, but many of its documents have never been transcribed. Recently, a project called Codice Ratio used a combination...[Details]

When STM32 uses JTMS (PA13) and JTCK (PA14) as normal I/O ports, add the following code before initialization (the order cannot be reversed):   RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE); G...[Details]

Interrupts and timers implement a 24-hour clock. The program is as follows: #include reg52.h   #define PORTLEN P0   sbit bit_select = P2^0; sbit seg_select = P2^1;   unsigned char src = {0x3f,0x06,0...[Details]
