Message: 49956    Hi All,

 

I'm using a BF548-EZKIT and uClinux revision of 5877.

 

1) I brought up and running the frame buffer device and started the video_test application. Basically, it was working, but I experienced screen resolution problem. Only the upper half of the lissajous curve was displayed, the lower part was outside of the display area. Any idea what did I wrong?

 

2) I run the even_test application with /dev/input/event1 (touchscreen)  parameter, and it was working fine.

 

3) After these, I started MicroWindows. I experienced the same resolution problem (when running tuxchess application) and when I ran nxcal, it seemed that the touchscreen is not handled at all. Any suggestion or idea how to solve these problems?

 

Best regards,

Gyula

by default, the touchscreen is not an input device for microwindows

The video_test program uses FBIOGET_VSCREENINFO ioctl, so - in theory - there shouldn't be any scaling problem. In line 242, the

    bp = screen_width/2;

should be changed to

    bp = screen_height/2;

and the curve will fit into the screen.

 

Best regards,

Gyula
