Hal_adc_start_dma函数介绍

Web注意: 我这里因为没有设置连续转换模式,所以中断只会触发一次,需要再次使用HAL_ADC_Start_IT开启中断,如果需要实时的转换,可以将转换设为连续模式,这样的话ADC转换器便会实时的持续的进行转换,那将是非常消耗CPU的,以至于main将不能正常执行(采样时间太短的话)。 WebDec 4, 2024 · 关闭ADC 3种模式 ( 轮询模式 中断模式 DMA模式 ) • HAL_ADC_Stop() • HAL_ADC_Stop_IT() • HAL_ADC_Stop_DMA() ADC校准函数 : • HAL_ADCEx_Calibration_Start(&hadcx); .

How to enable ADC continuous mode with DMA? - ST Community

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.
