Same here. 不稳定,不是总没反应。我再用几天,如果难以忍受的话就退掉。

刷了cm10.1,赶脚很流畅啊,不刷确实不咋地

做了一个factory reset,然后规规矩矩register,更新到2.1,现在非常流畅,一切完
美,准备再去买一个。目前这个尺寸的没有更理想的,其它的要么7寸的网页还是看不
全,要么离4:3太远(太长,不好查看相机拍的照片),要么不到1080p(不好查看相机
录的视频)。7寸的板子必须要自带3g(打电话)和相机,否则毫无意义,因为是用来
取代手机的。9或10寸的是作为手机的补充,用手机做hotspot就可以了,相机也没有用
,主要是用来看全网页,照片和视频,和remote desktop等需要大屏幕的。

触屏是不太灵敏,可以关闭屏幕对着光仔细看看,会发现屏幕上面的触摸点阵非常稀疏
,估计是从成本考虑用了相对低廉的触摸原件造成的。

Ok, so regarding touchscreen, I uncovered this manual, that does not seem to
be 100% matching wrt defaults, but otherwise seems to be pretty much spot
on: http://newhavendisplay.com/app_notes/FT5x06.pdf
Now people that have issues can experiment with values and report their
findings and we might devise new defaults from it.
Registers are accessible from userspace too. The first table is controlled
by:
/sys/bus/i2c/drivers/ft5x06/3-0038/wmreg and /sys/bus/i2c/drivers/ft5x06/3-
0038/wmval
so in adb shell do echo 0xXX >/sys/bus/i2c/drivers/ft5x06/3-0038/wmreg (
replace XX with register number) to set register you are interested in
then you can do cat /sys/bus/i2c/drivers/ft5x06/3-0038/wmval to inspect the
value, or echo 0xXX >/sys/bus/i2c/drivers/ft5x06/3-0038/wmval to set the new
value.
cat /sys/bus/i2c/drivers/ft5x06/3-0038/tpreset seems to mostly reset
controller, but not to 100% default state.
If you screwed up, just press the power button twice (so suspend/resume) and
the thing will reset into the default state.
When experimenting with all of this, make sure your screen is actually on
too.
There's some sort of autocalibration that you can perform by doing cat /sys/
bus/i2c/drivers/ft5x06/3-0038/storecalibrateflash but I do not see any
change after it.
Anyway, what I found so far:
the 0x80 register controls touch sensitivity in a way, the smaller the value
, the higher the sensitivity. default 0x11, at 0x50 I can no longer register
any input, at 0x40 input is very sporadic. So people that complain about
oversensitivity might want to give this one a try.
There are registers for temperature compensation, water on the surface
compensation and such that I cannot seem to see make any difference, but it
might for others?
register 0xA0 for autocalibration, if you enable that - touchscreen goes
crazy with tons of phantom events, dong cat on tpreset stops it, but the ts
is still somewhat in weird state as you will be able to see if you decide to
try it.
Anyway, the documentation is very lightweight so there's a lot of
experimenting to be done by interested parties, please share your results!
