ELI5 - Setting up and running MOP-GL12232B-BGFW

Post by monkeypatch »

I have this parallel graphic display: http://www.matrixorbital.com/Parallel-D ... _info.html

Datasheets: http://www.matrixorbital.ca/manuals/MOP ... ED1520.pdf and http://www.matrixorbital.ca/manuals/MOP ... 12232B.pdf

I am very new to serial programming and I am having a hard time understanding how to get the timing correct so I can start sending commands to this display. If any non-novice electrical people could spread some knowledge I would be indebted. I have a RPi and an Arduino both purchased through adafruit, either could drive them but for now I am try to attempt with my Arduino.

More info:

I have

Code: Select all

LCD Pins => Arduino Pins

Pin1(Vss):  Ground               => GND
Pin2(Vdd): Voltage for logic => 5v
Pin3(V0):   Contrast             => Not connected 
Pin4(RS):   Register Select    => 0
Pin5(CS1): Chip Enable (L)   => Not connected
Pin6(CS2): Chip Enable (R)   => Not connected
Pin7(CL):  Clock                  => Not connected
Pin8(E):    Enable                => 1
Pin9(R/W): Read/Write       => GND (I do not want to read from LCD)
Pin10(DB0): Data bit 0         => 3
Pin11(DB0): Data bit 1         => 4
Pin12(DB0): Data bit 2         => 5
Pin13(DB0): Data bit 3         => 6
Pin14(DB0): Data bit 4         => 7
Pin15(DB0): Data bit 5         => 8
Pin16(DB0): Data bit 6         => 9
Pin16(DB0): Data bit 7         => 10
I've tried sending the instruction codes as set in the manual but I cannot get the display to respond.
My more concise questions are:

UPDATE: After more research I realize that CS1 and CS2 set which side of the display I need to write to.

1. Does the clock need to be connected to a pin?
and if so do I need to modulate the pin high/low at a specific rate?
2. How do I get the timing correct for this display so I can start sending commands and data?


Sorry for my noobness!
