So I've been building and testing along the way. I can't get the display to work and have tried the troubleshooting tips but no luck. I have done a couple of things differently so I was hoping I could get your feedback as to whether these differences should matter. First off I didn't have any 10k ohm resistors on hand - I had some 8.1k and 2.2k so I wired them in series to make 10.3k ohm. I did this everywhere it asked for 10k. I have a large number of capacitors around but no .1uf. or 10uf so I've omitted the capacitors on the backlight line and the reset line. I figured these were just to smooth the current out and wouldn't affect operation but I could be wrong. Any ideas? [edit] - I added the capacitors and it made no difference. I then built a test circuit to see if my 5110s work and they work fine. This is quite frustrating
