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]
Site conditions: 1. AD acquisition, DMA transmission; AD is set to single-channel continuous mode, DMA is set to single-shot mode. The upper threshold of the AD analog watchdog setting is less than t...[Details]
1. Function and purpose There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[Details]
OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
Today I am using the AD function of the stm8s microcontroller. There are ten channels from AN0 to AN9 on the microcontroller. I want to use only three of them, AN5 to AN7. //ADC initialization void A...[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]
;Question: The 80C51 single-chip microcomputer has a fosc = 6MHz. It is required to use the T1 timer working mode 1 to perform a timing of 40ms. And P1.7 periodically outputs a rectangular wave with ...[Details]
