STM32L071 and USART4

[vrollei]

Hello,

I am trying to add support of STM32L071 and USART4 and stack on STM32_UART4_RX_DMA_CHN STM32_UART4_TX_DMA_CHN parameters.
How/where can I find these params?

Thanks in advance!

Hi all DMA definitions are in the registry file under /os/hal/ports/STM32/STM32L0xx

I mean values of params.

There is a table in the Reference Manual under the Chapter DMA.

[vrollei]

get it, it is DMA_CSELR.

Thanks a lot!
