I don't know if anyone else has noticed this, but the test modes really do have patterns to them. Take this completely unoptimized program I threw together that doesn't even take advantage of port (C):
Code:
Based on the number put in place of 1C (valid inputs are 1C, 1D, 1E, or 1F), different patterns come up. Press any key to exit.
1C: Clean blue on the bottom portion of the screen. Stray lines above, but not that often.
1D: Bottom portion is still blue, but its a bit dirtier. No stray lines above.
1E: Jumpy lines everywhere, but more often in the higher half, and only every other line is a victim.
1F: Full blue, though some places are more intense than others.
All four inputs vary depending on what was on the LCD before the program was run. Also, put something on the screen beforehand and run the program. You'll notice that the patterns loop and never go randomly. You'll also notice the LCD fading if you don't think to stop the program after a little while.
So, was this already discussed elsewhere, or have I done something with my life?
