Re: working LCD driver

Hello,

I reread the mail about the lcd. Andrew has written :

I have tried this. Of course the SET GPLR(67) 1 does nothing when the ipaq is on,
but the SET GPLR(67) 0 just freeze the LCD on with the backlight on and the last
image of haret, but the touchscreen does not answer anymore. Does it mean that it is
the power of the MediaQ ?
