Project logs / Re: DIY breadboard breakout LCD module
Hi guys,

I'm new member in the forum ! So, I have some issues about interfacing nokia 1100 LCD with 16F84A microcontroller. Recently, I have created a 1100 lcd library (using asm language), and it works well under proteus and the program draws simple chars. However, the program did not work on the board either.

Anyone can help to solve this problem ?

Note: the board is powered by the USB power voltage, which is reduced using a simple voltage divider (2 resistors) and the voltage ranges between 2.9-3v.

Thanks in advance
