With the development of the automobile industry, more and more automotive electronic components are being used in modern cars, providing better safety, comfort and economy for cars. In the past, cars...[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 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]

DMA： 1. When using DAC, when the converted analog signal is output through the IO port, why is the IO port also configured to input mode? PS: The stm32 manual defines that PA4 and PA5 are connected...[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]
