How to set uo CTS to use as GPIO


I am using Serial port 1 in 2 wire mode. I would to use RTS and CTS as GPIO since they are not need for the serial port. Anyone know how to have I can do this on the ConnectMe 9210 development board. Any examples?

Many Thanks.

You will have do the configuring in the BSP gpio.h file. On page #42 of the “Digi Connect ME-9210 Hardware Reference” manual you will find the needed configurations.

According to the module’s pin-out chart, pin #9 (RTS) is mapped to GPIO[5] and pin #11 (CTS) is mapped to GPIO[1]

I hope this document helps.
