HAL_SPI_Transmit_DMA?

[bianchi77]

Guys,

Does anyone of you have experience on using SPI1 with DMA on STM32CubeMx?
I tried using this function HAL_SPI_Transmit_DMA(&hspi1, data, 3);

But I didn't see any response on my Logic analyzer..
Any ideas ?
I have initialize clock, GPIO, DMA and SPI setting according to STM32CubeMx setting...

Thanks

anyone ?

uint8_t data[3] = {0x01, 0x02, 0x03};
HAL_SPI_Transmit_DMA(&hspi1, data, 3);

But don't show how.

I'm not working specifically with STM32 DMA, in so far can't help in this regard. I would expect you have already done some things:
- checked SPI operation with non-DMA HAL functions. Seeing it working would reduce the problem to correct DMA setup.
- have read the HAL documentation and DMA examples thoroughly and implemented your DMA initialisation according to the example code

For the future, you should consider to learn in-system debugging with ST-LINK.
