Nokia Color LCD parallel port setup

  • Nokia color LCD inspiration from this page http://serdisplib.sourceforge.net/ser/nokcol_15g10.html
  • Bought a color display at the usual place for 200 INR.
  • Ckt similar to the 3310, driven by serial means but requires an additional Led backlight powersource. A variable adaptor set to 6V  provided enough backlight to view the LCD.
  • The trickiest part is the Nokia LCD connector (receptacle). The form factor is uSOP, pitch is 0.5mm. Wrecked a few by trying to solder it myself. Many alternatives were considered: getting a PCB made (costs quite a bit), importing a prototyping IC adapter such as the Epboard uSOP to DIP adapter about 6$ + shipping, getting some mobile repair people to rig it up. None of them worked and as usual the local repairmen were no good, most of them chose not to do it even if I would pay them handsomely
  • Finally asked the GD Guys. Sparkfun calls anybody who can solder 0.5mm a God and I had the privilege of getting one wire soldered by Nagaraj Nagarkar. Special thanks to the GD folks. Wouldnt have been able to do it without you.
  • Serdisp did nothing with the S1D15G10 with testserdisp. The assumption was it was a Nokia 6610.
  • Decided to try the N3510 driver. The screen came up with a lesser resolution 97x68.
  • Recompiled the n3510 driver with 130x130 and the results are below.
  • Weird!  Need to check this further.
