I am trying to continuously sample a ADC channel. When I have the overrun data preserved, I can see a valid value in the ADC Data register (Using the STM32CubeIDE debugger). However, when I try overwriting the overrun data, The only value I see in the data register is 0xFFF.
I also get the same issue when I enable the global ADC1/2 interrupt and start the ADC with HAL_ADC_Start_IT(), regardless of whether I have the overrun data preserved or overwritten.
I am using STM32CubeIDE and STM32CubeMX, and a ST-LINK v2. If something is unclear or I haven't mentioned something, Let me know. Any help will be greatly appreciated.
Edit:
Just for additional information, The system clock is 104Mhz, the ADC’s clock prescaler is set to asynchronous divide by 2, resolution is 12 bit, sampling time is 640.5 cycles.
