Reverse engineering the LCD interface
So I was having trouble getting the LCD working initially, so I ended up probing a working HDMI to LCD converter board sold by adafruit. You see, this board was driving my LCD just fine, but my FPGA couldn’t do diddly. So I wanted to see what I was missing.
This proved more difficult because of these 40-pin FPC connectors. Not sure what the pitch is, but it’s really freakin’ close together.
With a lighted magnifier (3x diopter?), and sharp o’scope probe, I was able to isolate individual pins on the 40-pin, long enough to hit the stop button on the scope.
