So a few months ago I asked the question on how to analyze a display. Since then I have found out much information about this board.
From some trace following it seems that
- Brown - DATA
- Red - CLK
- Orange - CS
- Green - GND
- Gray - 5v
Now the datasheet doesn't really say anything about having a Chip Select, but that little chip right below the input wires is a NOR gate and provides the functionality.
Here is my problem. I cant seem find any consistent way to communicate to the board using a Bus Pirate.
My setup is based on this post from Hack-a-Day. Which admittedly somewhat works, but is not consistent and works more like magic guessing. Could someone give me some insight on how to tackle this? Is the 2-wire mode on the Bus Pirate the best way to test this display?
