2.2'' TFT LCD mixed up colors

Post by nend »

Hello,

I've got a HY-TFT220 and get it work, but... when I use a other color then red the colors get mixed up (differcen random colors).
This works good (myGLCD.setColor(255, 0, 0);) everything else does'nt works good.
Is this a defect of the device?
Or is it a problem from the UTFT library.

Do you mean the colors get mixed up when you use the function myGLCD.setColor(255, 0, 0) ?

@Jack,

I'm meant that all the pixels in the display get meshed up when I’m not using the red color.

Now for using it for a couple of days most of the colors works ok but when I use the color yellow or white and the most colors between them the pixels get mixed up.
It's looks like a lot of death pixels (but then randomly)
Every time I push the reset on my Arduino other pixels get mesh up.

See the attachment and look at the white and yellow letters.
I think this will say enough.
