You could try to use the hardware trigger sample mode instead of the free running, and use the timer OV to trigger the ADC convention. SARADC 的工作模式是 continuous 模式,ADC 在执行完一次转换之后会直接进入下一次转换(不需要CPU干预),虽然你在 ADC EOS 中断中第一时间调用了 StopConvert(), 但是...
I did not look at all your code, but you're doing a lot in your timer ISR. Maybe this takes too long and the next timer interrupt is already generated when the previous one hasn't finished yet. Since the timer interrupt has a higher priority, the ADC's one will not pop up in bet...
