Application Notes

M16C/26A Group

Sample Program (Terminal Software)

1. Summary

This sample program shows the characters and numerals input from the keyboard of a PC on liquid crystal display by using the Renesas

Starter Kit for M16C/26A (R0K33026AS000BE).

(Straight type)

Received data

The extension board used here is a product

from PI System Co., Ltd.

2. Introduction

The example described in this document applies to the microcomputers listed below:

Microcomputers: M16C26A

This sample program runs on the Renesas Starter Kit for M16C/26A (R0K33026AS000BE).

Prepare an extension board available for the Renesas Starter Kit or create a circuit similar to the one shown in the example circuit on page

14 and then connect it to the Starter Kit.

This program uses RSK_LIB. For details about RSK_LIB, see the RSK_LIB reference manual. (RSK_LIB is the library software provided

for use with the Renesas Starter Kit for M16C/26A.)

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.

Personal computer (PC)

M16C26A

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.
