hi, where have you find crystalfontz 20x4 blue lcd for 10$? it is 29,80 on the site, and crystalfotnz it’s a direct seller.
it would be nice if you share with us your seller or ask if anyone need it at this good price not?
well, the LCD is an CFAH2004A-TMI-JP 20x4 STN Blue, Negative, Transmissive, White Edge LED Backlight, in this thread http://www.midibox.org/forum/index.php/topic,9623.0.html people had buy same LCD but with different color for MB-6582 Wilba user-project.
as Wilba says:
It’s a standard character LCD using the HD44780 industrial standard, the default LCD type for MIOS.
The only thing worth noting is that white backlight LCDs are edge lit (not a LED array underneath)… they will therefore use less current (maybe only 60mA?) and the brightness control of the Core PCB might not work as expected - you can use a 100ohm resistor in series with +5v/ground to pins 15 and 16 as an alternative, if you are paranoid and worried about burning out the LEDs.
I bought one of these blue LCD’s from Divineo awhile ago when they were mentioned in the MB6582 thread.
It is very nice and have had absolutely no problems with it. I got the data sheet from the CrystalFontz website.
Wilba was correct in saying the backlight adjustments on the Core module don’t seem to have quite the same range as with most other displays, but I haven’t found it to be a problem. Changing some resistor values would probably fix this issue anyway.
