Is there a library or example that shows how to do interrupt and DMA I/O over a with a STM32 UART without using the HAL drivers?
I've been able to figure out how to do basic interrupt and DMA I/O on both STM32L4 and STM32F4 UARTs with the HAL Library. But I'd sure like to figure out how to do this without the burden of the HAL libraries. Can someone point me at a complete ex...
