Sample Program (Terminal Software)

4. Operational Outline

When characters are input to HyperTerminal (keyboard of a PC), the program shows the input characters on liquid crystal display.

Connect the serial port (RS-232C) of a PC and the D-sub connecter on the microcomputer side with a straight cable, then enter characters

in HyperTerminal. The input characters are shown on liquid crystal display along with a buzzer tone.

Up to 16 characters can be displayed, not including BS and TAB codes.

The operation described above is accomplished using the following microcomputer facilities:

• Timer A0 (timer mode, main 2 ms cycle)

This timer counts 2 milliseconds using the main clock of the microcomputer as the count source.

It is used as the basic timer of RSK_LIB.

Time management, key scan and LCD display management are performed using this timer.

• UART2 (clock-asynchronous serial I/O mode, data reception)

It produces a transfer clock from the main clock of the microcomputer to receive the data transmitted via HyperTerminal.

• Timer A1 (pulse modulation mode, buzzer output)

This timer outputs a waveform with different high and low pulse widths using the main clock of the microcomputer as the count source.

It is used to sound a buzzer to notify data reception at terminal.
