hello.
what would be the best way to interface a keypad in an LCD using an MCU (PIC16F877A)?
i'll be interfacing 5 - 7 keypads, so will it be ok using an MM74C922 encoder considering the cost for the additional MM74C922 ?
i would like to hear other methods about interfacing keypads in LCDs using MCU.
all comments are welcome. thanks. ^^
