STM32CubeMX generate "feature not supported" instead ...

[NRoss]

The STM32CubeMX generate:

```

#define LCD_SPI_Send_DMA(rd, ln)           BSP_ERROR_FEATURE_NOT_SUPPORTED

```

instead if I modify the generated DISPLAY/Target/lcd_conf.h with

`#define LCD_SPI_Send_DMA BSP_SPI1_Send_DMA`

seems work correctly.

I am using:

• Nucleo WB55RG
• GFX01M1
• STM32CubeIDE 1.9
• X Cube Display 2.1.0 (in the package 2.0.0 was correctly defined)

Is this only a STM32CubeMX bug or I can't use SPI + DMA+ Display?

Thanks for the support

Hello @NRoss​ ,

The BSP_ERROR_FEATURE_NOT_SUPPORTED can be removed by applying the right settings in SPI1 config.

I see that you used SPI1 interface for ILI9341, so you need to navigate to SPI1 configuration and enable both TX and RX DMA requests.

By re-generating the code, you will get the following lines in lcd_conf.h file.

#define LCD_SPI_Send_DMA                    BSP_SPI1_Send_DMA
#define LCD_SPI_Recv_DMA                    BSP_SPI1_Recv_DMA
#define LCD_SPI_SendRecv_DMA                BSP_SPI1_SendRecv_DMA

I hope this helps :smiling_face_with_smiling_eyes:
