In our common sense, the word technology often has two definitions. The first is the technology sealed in the laboratory. They are like flowers on the mountain top. Only a few people on the mountai...[Details]

I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]

According to foreign media reports, the 2018 GMC Terrain Denali is equipped with multiple collision detection systems, and a recent test verified the safety of the system. Even when driving in a bu...[Details]

    This paper combines embedded control technology with network control technology to realize the design of temperature control system based on single chip microcomputer through Internet control. Th...[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]

ADC Introduction:     ADC (Analog-to-Digital Converter). That is, converting analog signals into digital signals for processing. When storing or transmitting, analog-to-digital converters are almost ...[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]

The first one is a DMA mode of multiple channel acquisition void ADC_DMA_Config(void)  { ADC_InitTypeDef ADC_InitStructure; RCC_HSICmd(ENABLE); while (RCC_GetFlagStatus(RCC_FLAG_HSIRDY) == RESET);  ...[Details]

Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]

This program sets the LED running light and the 0-16 numbers of the 0th position of the digital tube to light up in a cycle. The digital tube program cannot be put into the main function, because the...[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]

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]

A simple experimental programming question for the microcontroller: write a 3-byte binary addition subroutine. The program entry is: addend 1: 22H, 21H, 20H three bytes, 22H is the highest bit; adden...[Details]
