关于F3定时器触发ADC采样
刚接触F3，发现F3的ADC库和F1的不一样，F1可以通过ADC_InitStructure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_Rising;
ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_T1_CC1;
来设置定时器触发，
现在变成ExternalTrigConvEvent和ExternalTrigEventEdge，只能选1~15个通道的上升下降沿触发，不知道怎么设置
求解惑
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;

另外,F3好几个参考手册对应不同子系列。
