WebThe HAL library had the same bug as the code above. To solve it, either: Set the CR2_DDS bit, as in the accepted answer. However this might cause overrun error, as data is continuously converted. Clear the CR2_DMA bit before setting it again (or call ADC_HAL_Start_DMA) to start the sampling again. WebDemo 3: DMA with ADC. The DMA is a great tool to use with the ADC when you want to transfer lots of samples to memory continuously. It can be used for audio sampling, a custom oscilloscope, etc. The STM32 HAL makes it a little easier to use, as there’s some built-in functions that control the DMA with the ADC, specifically.
