FEZ to FEZ Serial comm with CTS/RTS


#1

Guys,

does anyone have an example on how to establish serial communication between FEZ boards using CTS/RTS ?

Thanks


#2

I can give you few hints:
There is a UART(COM) port on each FEZ Board that supports hardware handshaking.
In the code add this

_port.Handshake = Handshake.RequestToSend;

If you are connecting two FEZ Boards then connect:
RX <–>TX
TX <–>RX
CTS<–>RTS
RTS<–>CTS

Note: I assume that you are making direct connection with the TTL levels (Not RS232 levels).

Thanks Joe,

I suppose this line has to be on both FEZ boards?

_port.Handshake = Handshake.RequestToSend;

And all the magic will happen behind the scenes, right?

Indeed, straight pin to pin connections.
