Dear All,

I'm using the Wince 6.0 BSP on the SAM9263. I have changed the LCD from the 240x320 16bpp color LCD to a 320x240 16bpp color LCD: I have correctly set the new value on the lcdc.reg as you see below and everything seems good but I have some problems with the refresh (the cursor has the arrow with a black line, when I close the explorer some icons remain visible in the central part of the LCD. Maybe is something related to the 2DGPE, but I have checked that the parameters height and width are correctly setted.
Have you some ideas?

Many thanks in advance
bob

Hello
Just to add another information I can't see the background strip on the desktop where is displayed the windows CE built date and especially in this zone I have refresh problem. Is something related with the configuration of the video memory buffer?
Thank you
bob

Resolved! memory setting issue.

many thanks

Hello-
i'm in a similar situation, but having errors when trying to rebuild.

Does your new LCD that's in 320 x 240 use DE mode like the original Hitachi panel?

or something with VSYNC and HSYNC

if VSYNC, would you be willing to assist with enabling the VSYNC in Win CE?

i'm having trouble and wondering exactly what steps you took

THANKS!
-Evan
