This program uses the eight-channel ADC single acquisition mode. According to the configuration, ADC12SC will automatically reset after the conversion is completed in the single mode, so it is necess...[Details]
1. Common knowledge about DMA. 1. Function: to achieve high-speed data transmission between chips. That is, it can achieve data transmission without occupying the CPU. 2. Mode: There are three tran...[Details]
1) ADC multi-channel acquisition: (Multi-channel acquisition must use scanning mode. In scanning mode, the channels of the rule group share a register, so DMA transmission must be used; to prevent da...[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]
