STM32: FIFO for Serial

[ser-plu]

Hi, guys

I wanted to use the standard UART driver for STM32G431, and I have found that there is no implementation write/read buffer, and it even does not use the hardware FIFOs. Is it correct or do I miss something? How would you suggest then to send/receive long data via serial? Do you have any templates?

The buffer is disabled by default, you may enable it via lbuild options buffer.tx, buffer.rx for each instance individually. I'm not certain if the driver uses hardware FIFO though.

Thanks. The buffer option is what I was looking for.
