SPI+GPDMA Configuration

[OrionJ]

Besides, I don't know whether this configuration of MX is correct.

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_GPDMA1_Init();
  MX_SPI2_Init();
  MX_ICACHE_Init();
  MX_I2C1_Init();
  MX_RTC_Init();
  /* USER CODE BEGIN 2 */
HAL_I2C_MspInit(&hi2c1);
HAL_SPI_MspInit(&hspi2);
HAL_RTC_MspInit(&hrtc);

Hello @OrionJ;

The configuration depends on your requirement.

Could you give more detail about your project context and requirement?

May SPI_FullDuplex_ComDMA_Master example can help you. This example explains how to handle an SPI as a Master to perform a data buffer transmission/reception between two boards, using DMA.

Thank you.
