arm9中 用的tslib校准触摸屏。800x480的分辨率,内核中以及板子中的环境变量都设置了。把这些工作都做完了之后 按照教程 ./ts_calibration 出的的五个坐标值不对校准不对。结果如下。
xres = 800, yres = 480
Took 13 samples...
Top left : X = 1520 Y = 1749
Took 10 samples...
Top right : X = 2577 Y = 1757
Took 11 samples...
Bot right : X = 2457 Y = 1165
Took 15 samples...
Bot left : X = 1521 Y = 1190
Took 7 samples...
Center : X = 2083 Y = 708

./ts_test中 划线也画不成。乱糟糟的。 哪位有经验的大神给个提示,不知道改哪。谢谢! |
