ohh.. thanks for the tutorial.. appreciate it.
btw, is it possible to interface a keypad to 2 or 3 or more LCDs using 1 MCU ?
i'm using a PIC16F877A. what i want to do next is, i want to input different data and
interface those data in their corresponding LCDs. for example, using 1 keypad, 1 mcu, and 3 LCDs
input data1
interface data1 in LCD1
input data2
interface data2 in LCD2
input data3
interface data3 in LCD3
that sort of thing. i wonder if it is possible. thanks. ^^
