ChibiOS Free Embedded RTOS

I have an application which needs 9 data bits on the USART. From what I can see, the ChibiOS serial driver cannot be used for this as it explicitly uses 8 bit queues?

Could someone confirm I have to use the USART driver if I want to send/receive all 9 bits? if so that's a real pain and would be good if it's considered for a change in the future.

Hi,

The driver assumes queues of bytes, it is not possible to change it. You should look into the UART driver instead, that one could be enhanced.

Yeah I've changed the code over to the UART driver - it was much easier than I thought, thanks to the good examples in the testhal folders. Thanks Giovanni!
