• Manufacturer Part Number: MC144032B6WCB-SPTLY
• Description: LCD, 144X32, STN, Y/GN B/L, CHINESE; Backlighting Colour: Yellow Green; LCD Display Type: STN; Pixel Size (H x W): 0....
• Manufacturer: Midas

● EXTENED FUNCTION SET
● SET IRAM OR SCROLL ADDRESS
● SET GRAPHIC RAM ADDRESS
In same instruction cannot alter DL, RE and G at once. Make sure that change DL or G
first and then RE.
DL : 4/8 BIT interface control bit
RE : extended instruction set control bit
G : Graphic display control bit
SR=1: AC5~AC0 is vertical scroll displacement address
SR=0: AC3~AC0 is ICON RAM address
Set GDRAM address to address counter AC .
First set vertical address and then horizontal address(write 2 consecutive bytes to complete
vertical and horizontal address set)
Vertical address range is AC6...AC0
Horizontal address range is AC3…AC0
The address counter AC of graphic RAM(GR AM) only increment after write for horizontal
address. After horizontal address=0FH it will automatically back to 00H. However, the
vertical address will not increase as the result of the same action.
code
