原谅我的英语。
我想在 HAL 中设置 DCMI，因为使用 CooCox 必须从生成器 cubeMX 中复制代码
编译器不喜欢以下行：
__HAL_LINKDMA(hdcmi, DMA_Handle, hdma_dcmi);
代码：
void DCMI_DMA_init(void){
GPIO_InitTypeDef GPIO_InitStruct;
__GPIOE_CLK_ENABLE();
__GPIOA_CLK_ENABLE();
__GPIOC_CLK_ENABLE();
__GPIOD_CLK_ENABLE();
__DCMI_CLK_ENABLE();
__DMA2_CLK_ENABLE();
HAL_NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_2);
HAL_NVIC_SetPriority(DCMI_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(DCMI_IRQn);
/*
