Moreover, this avoids risk of overrun for low frequency applications. This parameter can be set to ENABLE or DISABLE. - Note: Do not use with interruption or DMA (HAL_ADC_Start_IT(), HAL_ADC_Start_DMA()) since they clear immediately the EOC flag - to free the IRQ vector sequencer. + Note: It is not recommended to use with interruption or DMA (HAL_ADC_Start_IT(), HAL_ADC_Start_DMA()) since these modes have to clear immediately the EOC flag (by CPU to free the IRQ pending event or by DMA). + Auto wait will work but fort a very short time, discarding its intended benefit (except specific case of high load of CPU or DMA transfers which can justify usage of auto wait). Do use with polling: 1. Start conversion with HAL_ADC_Start(), 2. Later on, when ADC conversion data is needed: use HAL_ADC_PollForConversion() to ensure that conversion is completed and HAL_ADC_GetValue() to retrieve conversion result and trig another conversion start. (in case of usage of ADC group injected, use the equivalent functions HAL_ADCExInjected_Start(), HAL_ADCEx_InjectedGetValue(), ...). */ |
