Minimal DMA-based UART driver for STM32F746
Hi there,
Did you ever get this working?
Having a look at usart_dma_sendArray
I can see the following line
DMA2_Stream7->CR |= DMA_SxCR_DIR_0; //set direction memory to peripheral
However RM0385 Rev 8 datasheet says 00 is peripheral to memory, and 01 is memory to peripheral. I can't seem to get your example working but I'm assuming this particular line is a misunderstanding on my part?
Thanks and Kind Regards,
Blaise
