HAL_UARTEx_ReceiveToIdle_DMA support on STM32MP15 products

[cfilipescu]

Is HAL_UARTEx_ReceiveToIdle_DMA supported on STM32MP15 products? If so is there an example for using it?

Hi @cfilipescu​ ,

The CubeMP1 HAL does not contain HAL_UARTEx_ReceiveToIdle functions, but you could easily reuse them from CubeH7 which share almost same UART/USART HW.

See also this H7 post which also link to an interesting page: https://github.com/MaJerle/stm32-usart-uart-dma-rx-tx#idle-line-or-receiver-timeout-events

Not a concrete example so I can't select it as best answer.

And also see this link to understand how ridiculous and incompetent the HAL API design is...

I'd imagine anything you engineer will be better than anything in, or missing, from the deeper HAL implementation.
