TMS320F28335: Forward serial data from one port to another

Alessio Caligiuri
Prodigy 100 points

Part Number: TMS320F28335

Hi all,

I have a system with TMS320F28335, whose serial ports are connected as follows:

- SCI A: FTDI USB-serial converter (then connected to a PC)

- SCI B: not used

- SCI C: directly connected to another microcontroller.

I need to realize an internal connection between SCI A and SCI C. The system should behave like if the device connected to SCI A is directly communicating with the device connected to SCI C. In other words, I need to forward serial data from one port to another, in both directions.

I am thinking to write two simple routines to receive data from a port and send the same data to the other port. My hardware is fixed so I cannot add other circuits or wirings.

Any bettter ideas?

Many thanks,

Alessio
