GU-3900B series “General Function” Software Specification
5.4.1.3
STX 44h DAD 53h aL aH
(Display start address)
Code:
02h 44h DAD 53h aL aH
DAD:
Display address
aL:
Display start address, lower byte
aH:
Display start address, upper byte
Definable area:
00h ≤ DAD ≤ FFh
0000h ≤ (aL + aH×100h) ≤ Max_DispMemAddr
Function:
Set the Display start address (top left position of display screen).
Command is ignored if Display start address is outside the definable area.
Example for 256×64 dot module:
5.4.1.4
STX 44h DAD 57h 01h
(Display synchronous)
Code:
02h 44h DAD 57h 01h
DAD:
Display address
Definable area:
00h ≤ DAD ≤ FFh
Function:
Synchronizes the next command with internal display refresh cycle.
Smooth scroll display is possible by using this command in combination with “Display start address”
command.
5.4.1.5
STX 44h DAD 58h n
(Brightness level)
Code:
02h 44h DAD 58h n
DAD:
Display address
n:
Brightness level setting
Definable area:
00h ≤ DAD ≤ FFh
00h ≤ n ≤ 04h, 10h ≤ n ≤ 18h
Default:
n = 04h or Memory SW setting.
Function:
Set brightness level, as shown below.
