Re:UART comm w/ hardware flow control code?

Hi,

The configurable FIFO interrupt trigger levels will help you with RTS/CTS control, although at 9600 I doubt if you would have any trouble processing all the information you need with the 6965 even if you use a CRC. Assuming you're running it at full speed.

The UART block used by Luminary is very good, one thing I like is that you don't have to check error status separately, it gives you error information in the upper bits of the FIFO data. So if you have a comms problem you know which bytes are good or bad in the FIFO without any extra work.

I use some spare GPIO for RTS/CTS on one of my ports, but haven't got around to writing the code to control them yet, even at 115,200 and beyond I don't appear to need it, although having proper control is always a better plan!

Regards,

Liam.
