2、 STM32H7的自带外设比较之前的任何STM32型号都要生猛,算是大换血了,换了ADC,DMA,USART等重要外设,性能比之前要强劲很多。比如ADC换成了3.6Msps 16位分辨率,DMA支持任意互联了,USART也支持波特率自适应。 3、 到了STM32H7系列,ST官方仅提供了HAL库,没有再提供标准库,而对于F1,F4系列,标准库和HAL库都是有...
(++) Analog mode is required when a pin is to be used as ADC channel or DAC output. (++) In case of external interrupt/event selection the "Mode" member from GPIO_InitTypeDef structure select the type (interrupt or event) and the corresponding trigger event (rising or falling or both)....
