پاسخ : سوال در مورد STM32 - ADC

درود
لطفا برنامه راه اندازی adc رو هم قرار بدین .شاید مشکل از برنامه ست مثلا کلاک adc2 رو تو برنامه enable نکردید . با کدوم کتابخونه adc رو راه انداختین HAL یا cmsis ؟

من CubeMX, و HALL استفاده میکنم.
برنامه ای که واسه تست نوشتم خیلی سادست.
یک LED واسه نیم ثانیه روشن میشه و مقدار ADC1 خونده میشه و روی پورت B قرار میگیره. تا اینجا درسته و مشکلی نیست و مقدار رو نشون میده.
بعد LED خاموش میشه و باید مقدار ADC2 خونده بشه و روی پورت قرار بگیره، ولی مقدار صفر رو نشون میده.

اینم برنامه:
