How to read ADC without DMA ?????
Board: NUcleo 64-G474
I just want to read 2 channels of an ADC but am presented with a bewildering array of incredibly confusing options: Ranks, Continuous mode, discontinous mode, number of conversions, oversampling, triggers, etc, etc, etc. The embedded "help" is completely useless.
I have two SE channels of ADC1 enabled (1 and 2), and I want to sample them both NOT in DMA. Seems reaonsonable but after hours of trying I can find nothing that works, and no resources to help. I'm trying the code below and various offshoots of it.
while (1)
{
HAL_ADC_Start(&hadc1); // start the adc
HAL_ADC_PollForConversion(&hadc1, 1000); // poll for conversion
adc1_val = HAL_ADC_GetValue(&hadc1); // get the adc value
HAL_ADC_Start(&hadc1); // start the adc
HAL_ADC_PollForConversion(&hadc1, 1000); // poll for conversion
adc2_val = HAL_ADC_GetValue(&hadc1); // get the adc value
HAL_ADC_Stop(&hadc1); // stop adc
printf("adc=[%d, %d]\n\r", adc1_val, adc2_val);
