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

Message: 49968 the video_test program is very simple ... it does not scale itself
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
