是有些差别，但差不多的。 ST官方的RM0316的12.4.17章节有介绍。 除了事件触发外，同样可以软件启动！ 至于怎么设置，找个库例程看看。差不多的。 以STM32F302/303为例。 AdcHandle.Init.ExternalTrigConv = ADC_SOFTWARE_START; AdcHandle.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE; *************************************************** #if defined(STM32F302xE) || \ defined(STM32F302xC) /*!< List of external triggers with generic trigger name, independently of */ /* ADC target (caution: applies to other ADCs sharing the same common group), */ /* sorted by trigger name: */ /*!< External triggers of regular group for ADC1&ADC2 */ #define ADC_EXTERNALTRIGCONV_T1_CC1 ADC1_2_EXTERNALTRIG_T1_CC1 #define ADC_EXTERNALTRIGCONV_T1_CC2 ADC1_2_EXTERNALTRIG_T1_CC2 #define ADC_EXTERNALTRIGCONV_T1_CC3 ADC1_2_EXTERNALTRIG_T1_CC3 #define ADC_EXTERNALTRIGCONV_T1_TRGO ADC1_2_EXTERNALTRIG_T1_TRGO #define ADC_EXTERNALTRIGCONV_T1_TRGO2 ADC1_2_EXTERNALTRIG_T1_TRGO2 #define ADC_EXTERNALTRIGCONV_T2_CC2 ADC1_2_EXTERNALTRIG_T2_CC2 #define ADC_EXTERNALTRIGCONV_T2_TRGO ADC1_2_EXTERNALTRIG_T2_TRGO #define ADC_EXTERNALTRIGCONV_T3_CC4 ADC1_2_EXTERNALTRIG_T3_CC4 #define ADC_EXTERNALTRIGCONV_T3_TRGO ADC1_2_EXTERNALTRIG_T3_TRGO #define ADC_EXTERNALTRIGCONV_T4_CC4 ADC1_2_EXTERNALTRIG_T4_CC4 #define ADC_EXTERNALTRIGCONV_T4_TRGO ADC1_2_EXTERNALTRIG_T4_TRGO #define ADC_EXTERNALTRIGCONV_T6_TRGO ADC1_2_EXTERNALTRIG_T6_TRGO #define ADC_EXTERNALTRIGCONV_T15_TRGO ADC1_2_EXTERNALTRIG_T15_TRGO #define ADC_EXTERNALTRIGCONV_EXT_IT11 ADC1_2_EXTERNALTRIG_EXT_IT11 #define ADC_SOFTWARE_START ((uint32_t)0x00000001) 另外,F3好几个参考手册对应不同子系列。
