我的电容触屏特别不灵敏
如题，我的电容触屏特别不灵敏，在qt的那个主界面上的时候还可以，等点击进入下面子窗口的时候，触屏就不太好用了，尤其是那个关闭窗口按钮，可能要点几十下才能偶尔关闭，我初步估计是触屏校准与窗口上的图标不匹配，这个应该怎么做？我想重新校一下屏，除了重新初始化rootfs系统外，还能怎么做？谢谢 建议lz将屏幕的外壳去掉，屏幕的外壳影响了屏幕边角的触摸是用 l谢谢楼上，不过把外壳去了，也没改善 我把ft5x06_ts.c中的printk("Linux Touch down,it is start \n");和printk("Linux Touch up,it is end \n");打开了按键正常的时候有Linux Touch up,it is end输出，怎么按都没反应的时候就只有"Linux Touch down,it is start输出。 我把从i2c总线上读出来的数据上上看，如果触摸时间稍长一点，从i2c读出来的数据就不正确，只能快速的点击看着数据才能正常一点，还有就是每个子串口的关闭按钮感觉是点不到正确位置上，偶尔能有效。快速点击正确的打印数据是recdata=0,0,11,1,5a,5a,0,fe,0,0
start read_data i2c_rxdata OK
Touch down, x=15a y=fe
Linux Touch down,it is start
button down
recdata=0,0,11,81,5a,5a,0,fe,0,0
start read_data i2c_rxdata OK

recdata=0,0,10,41,5a,5a,0,fe,0,0
Touch up,it is end !
start read_data i2c_rxdata OK

其中recdata后面跟的是i2c读出来的数据，这个数据从协议上看是正确
稍微按触屏的时间长一点，也就是点击的2-3倍吧

从数据上看没有抬起动作，后面还有好多ff的值，从这个现象上看是触屏本身发出来的数据不正确
点击关闭串口按钮的那个X键

感觉事件时触发了，但是串口也关闭不上，偶尔能关上，不知道这是什么原因
楼上朋友，如果是Linux系统建议您选择电阻屏，Linux电容屏触摸驱动我们这边也在优化改进，后续会有新版本升级。
