最终发现把 MX_DCMI_Init();放到 MX_DMA_Init();即可正常传输数据 Several peripheral DMA handle pointers point to the same DMA handle. Be aware that there is only one channel to perform all the requested DMAs.干扰项,删掉就行不用管,我开始还以为这里需要配置什么东西,就保留最上边一行 ...
2、然后引用Init函数，USART_InitStructure并不是一个全局结构体变量，而是只在函数内部的局部变量，初始化...

44.2.2 ADC时钟源选择 ADC有两种时钟源可供选择,可以使用来自AHB总线的系统时钟(属于同步时钟,对应下面框图的adc_hclk),也可以使用PLL2,PLL3,HSE,HSI或者CSI时钟(属于异步时钟,对应下面框图的adc_ker_ck)。 结合上面的框图,ADC的时钟源要注意以下几个问题: ...
