官方EVT只有TIM+ADC和ADC+DMA，我試了幾種合并，但是最終還是沒實現(xiàn)，DMA傳輸完成中斷進(jìn)不去

有什么需要注意的點嗎

以下為全部代碼

https://www.cnblogs.com/wchmcu/p/17445959.html? 看下這個帖子 ，配置少了一點ADC_ExternalTrigConvCmd(ADC1, ENABLE);//? ?開啟外部事件觸發(fā)ADC啟動，ADC的外部觸發(fā)源與定時器的輸出源保持一致，也需要參考ADC外部觸發(fā)的框圖，注意觸發(fā)頻率不要大于ADC所有規(guī)則通道采樣完的這個時間。DMA的模式可以設(shè)為循環(huán)模式，這樣就不需要重新設(shè)置緩沖區(qū)與傳輸長度了。

已解決，謝謝?。。?/p>
