STM32H7 ADC3 setup fails

Daan1 · ‎2024-10-25

Hi,

I am trying to set-up the ADC3 for STM32H7 but the HAL_ADC_Init() fails ?

After debugging, I see that the function LL_ADC_IsInternalRegulatorEnabled() fails in HAL_ADC_Init(). I also see that DEEPPWD is 0 on reset but the datasheet say that it should be 1 on reset. Why is this so ?

regards,
Daan
