Web1. At first i write code for ADC with out DMA (ADC3, PF10 in) and it work excellent. I get positive knovlege. 2. At second step i tried to use DMA (DMA1 stream 1, PF10, ADC3), but code don't work. WebFor ADC Slave, ADC is enabled only (conversion is not started). For ADC Master, ADC is enabled and multimode conversion is started. To guarantee a proper reset of all interruptions once all the needed conversions are obtained, HAL_ADC_Stop_IT() must …

Webhadc1.Init.EOCSelection = ADC_EOC_SEQ_CONV; I also had to enable the overrun setting as well: hadc1.Init.Overrun = ADC_OVR_DATA_OVERWRITTEN; Without this the HAL_ADC_PollForConversion was still blocking. I do not fully understand why this was … WebJul 12, 2024 · The default setting of overrun is data preserved. Therefore, for compatibility with all devices, parameter overrun should be set to data overwritten. On this STM32 family, setting of this feature is conditioned to ADC state: ADC must be disabled or enabled without conversion on going on group regular. b-ortho https://sunwesttitle.com
