Hello,
I have 6 ADC channels that shall be launched by software in regular conversion mode. I set the ADC to "End of sequence" and enabled DMA to jump into the callback function when all channels are converted.
This is working fine so far.
I have another channel that shall be trigged by the falling edge of a PWM in injected mode. Therefore, I enabled the interrupts for the injected mode.
When I configure the ADC like this, it only jumps into the interrupt callback of the injected mode and never into the callback of the regular mode.
I use HAL Drivers like this:
// Set up DMA
HAL_ADC_Start_DMA(&hadc1,(uint32_t *)aADC1ConvertedValues, ADCCONVERTEDVALUES1_BUFFER_SIZE)
// software trigger
while(1)
HAL_ADC_Start(&hadc1)
// callback
void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *AdcHandle)
// Start injected conversion
HAL_ADCEx_InjectedStart_IT(&hadc1)
// callback
void HAL_ADCEx_InjectedConvCpltCallback(ADC_HandleTypeDef* hadc)
Do I also need to use interrupt mode for regular conversion? I didn't find an appropriate example so far.
