Re: UART serial Flow Control

You are right. Offloading the work done by the STM32 into an FPGA would be the correct thing to do instead of gluing something in between them.

Issue when selecting DUPLEX modem

I am having trouble connecting to Brandmeister when I select the DUPLEX modem. It is almost as if my security password is not set. But if I incorrectly change it to a SIMPLEX modem, it works consistently. ( nothing changed in security settings ) So this brings me to a 2 pronged question. #1: Anyone ...

UART serial Flow Control

I have read where you can enable FLOW CONTROL on the pi UART by assigning some GPIO pins to it. Now I realize the MMDVM's don't make use of Flow Control, but I just wonder if by chance it is active on the serial UART when operating in Pi Star. I'm wanting to glue an FPGA in between the PI and the MM...
