STM32 ADC synchronization rule mode (two-channel)

STM32 ADC synchronization rule mode (two-channel)

It feels better to directly paste the code ......

Some annotations are not supported if they are directly attached to Keil5 ....... So embarrassing .... Next time, the code comments will still be calculated in full English ,,,

Haha .. Any questions can be discussed together, and I don't know why the Classification CANNOT be embedded, so I have to click Linux ..
