CFAG240128L-TMI-TZ 8 pixels constantly on

[Stenu]

I've been working with this display for a while now and everything worked fine. Now I have 8 pixels on the display that are constantly on. Everything else still works fine. Is the display broken or what could cause this? I didn't do any display related software changes when this happened, all of sudden those pixels were on and won't go away.

Can you attach a picture of what you're seeing?

Yes, here it is.

For some reason I couldn't attach it here but hopefully this link works.

That looks an awful lot like a cursor. I would check your initialization, it should probably be something like this:

void LcmInit( void )
{
     LcmWriteCommandWith2Par(0x00,0x00,0x40);      //
     LcmWriteCommandWith2Par(LcmLengthDots/8,0x00,0x41);      //
     LcmWriteCommandWith2Par(0x00,0x08,0x42);      //address 0x0800
     LcmWriteCommandWith2Par(LcmLengthDots/8,0x00,0x43);      
     LcmWriteCommand(0xA0);                  //CURSUR 8x1
     LcmWriteCommand(0x81);                  //Xor
     LcmWriteCommand(0x9C);                  //TURN TEXT AND GRAPHIC ON
}

Well, I feel quite stupid now, it was indeed the cursor... Sorry and thanks!

Never a problem. Glad it was easily resolved.
