Introduction
Support point, line and rectangle drawing
A129 is an 128X64 dots Graphic LCD Module
functions.
Support block save (512KB volatile
designed for system to display messages. The
memory), and block recall functions.
maximum allowed 8 lines and 21 columns
characters to be shown in one screen. The device
Implementation
is easy to install because it uses only a 2-wire
The device consist of two major components:
RS232 Transmit and Receive interface to

One A129 board

One UART Cable

for +5V power supply and ground connectivity.
Based
on

How to store a block and display on the LCD
A129 implement a 512K bytes of Flash ROM
memory which could store approximately about
260,096 display points (where one point will
occupy 2 byte of memory) and which could be
separate into 8 big block set and one big block
set own 256 block maximum, each block will be
assigned a block number from 0 to 255, and will
