Meh, finally had some time to play around with this thing and it still wont display anything.
I read the HardOCP post and realized the pinout he traced was one different than the one I was given, which was the wr and rd pins were flipped. Ive hooked it up according to the schematic on this site yet my LCD still will not display anything. Ive checked and double checked the wiring so im pretty boggled right now.
Heres how i have it connected now:
Code:
LCD DB25
01 D7 9
02 d6 8
03 d5 7
04 d4 6
05 d3 5
06 d2 4
07 d1 3
08 d0 2
09 cd 16
10 rd 17
11 wr 1
12 ce 14
13 reset
14 5v
15 gnd
16 ledgnd
17 ledgnd
18 ledgnd
Reset to +5v, LCD #15-18 to gnd, DB25 18-25 to gnd.
I was even a good boy and checked my wiring from the db25 and found a loose connection, but all work now, i can even place an LED in and watch it throb as the clock that the LCD should be displaying ticks away :\
All I can see on screen is a fully black screen when my constrast is all the way up, i would even be happy with some scrambled junk at this point. It doesnt even have any initilization lines.
Any ideas?
