Not seeing full DMA Initialization with CubeMx
With CubeMx, I've set up the DMA in Circular Mode, Data Width Half Word, Increment Address Memory. When I get the generated code, I only see the code below. Where are the other initialization parameters? Is it because the DMA channel interrupt is enabled that they're hidden?
static void MX_DMA_Init(void)
{
/* DMA controller clock enable */
__HAL_RCC_DMA1_CLK_ENABLE();
/* DMA interrupt init */
/* DMA1_Channel1_IRQn interrupt configuration */
HAL_NVIC_SetPriority(DMA1_Channel1_IRQn, 0, 0);
HAL_NVIC_EnableIRQ(DMA1_Channel1_IRQn);
}In the file stm32g0xx_hal_dma.c , I see the generic initialization routine shown below. But why I don't see it in the generated code?
HAL_StatusTypeDef HAL_DMA_Init(DMA_HandleTypeDef *hdma)
{
/* Check the DMA handle allocation */
if (hdma == NULL)
{
return HAL_ERROR;
}
/* Check the parameters */
assert_param(IS_DMA_ALL_INSTANCE(hdma->Instance));
assert_param(IS_DMA_DIRECTION(hdma->Init.Direction));
assert_param(IS_DMA_PERIPHERAL_INC_STATE(hdma->Init.PeriphInc));
assert_param(IS_DMA_MEMORY_INC_STATE(hdma->Init.MemInc));
assert_param(IS_DMA_PERIPHERAL_DATA_SIZE(hdma->Init.PeriphDataAlignment));
assert_param(IS_DMA_MEMORY_DATA_SIZE(hdma->Init.MemDataAlignment));
assert_param(IS_DMA_MODE(hdma->Init.Mode));
assert_param(IS_DMA_PRIORITY(hdma->Init.Priority));
