When i send the command (254 55) to read the module type. My GLK12232-25-WBL returns the hex value of 0xFF.

this is a problem with LCD tester and LCDproc, because they rely on the fact that the unit wil return a value of 0x22.

how can i fix this problem!?

Tnx again... problem fixed

tnx for the fast reply,

but now i have another problem in another topic

I was playing with my new LCD module. and it worked fine for a while. until i installed the winamp plugin. when i played a song the whole display was filled with a bunch of caracters and bitmaps, after that the module hanged.

from that point on the display didn't work properly annomore. when i ...

Do not under any circumstances use an unmodified floppy drive power cable.

This quote is from the user manual of the GLK12232-25-WBL

I have one and i am a bit confused. I don't think the powercable has to be moded for this type.

Or am i wrong ?
