Part Number: TMS320DM8148
Tool/software: Linux
Hi,
I am using custom dm8148 board.Here is what I meet:
when I use LCD-RES,I press at one point. the mouse cursor will jitter.
I change the $(rootfs)/etc/init.d/matrix-gui-e replace the "export QWS_MOUSE_PROTO="Tslib:/dev/input/event0 Auto:/dev/input/mice"" as "export QWS_MOUSE_PROTO="Tslib:/dev/input/event0""
It work better,but still have some jitter.
I try some ways to improve this.Here is what I try:
(1) change the .debounce_max = 10,.debounce_tol = 30,.debounce_rep = 1,
(2) change the ts.conf module pthres pmin=1 \ module dejitter delta=100
(3) slow down the spi and AD frequency,it just slow down the jitter,not eliminate
(4) use spidev_test application to test the spi,the result is right.
There is so wire,it is work fine at LCD-CAP.
I use ts_print to check the point address.If i keep press at one point,the x/y is difference of one or two pixels，so I think the LCD is work fine,but the QT do not look normal.
Here is my questions:
(1) Is there somewhere at software to debounce ?
(2) the ts_print result is fine,so is it possible only the QT display questions?
(3) I have used spidev_test to check the spi hardward design, but maybe TI have another way to exclude the hardward design questions?
Any help will be applicatied ~
Thanks.
