I'm currently trying to get the color display to work. First, trying it on an arduino duemilanove, I manage to get the following via the serial console using the built in graphics test:
which seem to be expected values. however, the screen is completely white. as far as i can tell everything is working - if i remove any of the pins, the diagnostics don't return the proper values.
could i have damaged/fried parts of the screen? i'm running it on 3.3V. also tried it on 5, and the only difference is that the backlight is quite a bit brighter. i also noticed that it gets a bit hot near the ribbon cable.
i'll try it with the teensy soon, but have a feeling it shouldn't make any difference?
p.s. on the teensy side, i've been looking at processing real time audio. did some timing of the FFT code - totally impressed by the amount of power it has!
Code:
ILI9341 Test!
Display Power Mode: 0x9C
MADCTL Mode: 0x48
Pixel Format: 0x5
Image Format: 0x9C
Self Diagnostic: 0xC0
Benchmark Time (microseconds)
Screen fill 2560992
Text 291960
... etc
