Other Parts Discussed in Thread: MAX3232
One end of a RS-232 cable is connected to a touchscreen, and the other end I cut and grabbed the RX/TX wires from it. I want to put the RX and TX wires into the pins of the microcontroller board and send messages via RS-232 communication to talk to this touchscreen.
I tried using the UART pins on the microcontroller board (SCI1 and SCI3 RX/TX), but it didn't work.
Can I configure pins on the microcontroller board to handle RS-232 communication?
I saw this on the datasheet, but it didn't really help me:
"The SCI module is a universal asynchronous receiver-transmitter that implements the standard nonreturn to zero format.
The SCI can be used to communicate, for example, through an RS-232 port or over a K-line."
