If your demo board has two TIA-232 connectors, then perform this experiment.
1. Connect one of the TIA-232 connectors to the PC so that you can download your
program onto the demo board.
2. Connect the second TIA-232 connector to another demo board.
3. Write a program to be run on two demo boards. The program outputs one character
per second to the SCI port that is connected to another demo board and then reads in
characters from the same SCI port.
4. The program displays the SCI activities on the LCD screen as follows:
The first row displays what has been sent out:
snd:
xxxxx . . .
The second row displays what has been received:
rvd:
yyyyy . . .
Only the last 16 characters sent and received will be displayed on the LCD screen if a
16 3 2 LCD screen is used.
