Hi,
I step in as everybody looking to find solutions for TS issues. Actually,
I'm still working on solving it. However, I have some tips and
"discoveries" I'd like to share, meby someone will find it useful.
1) I have just external TS, no cape at all, the TS is 10 inch.
2) I found "after many hours :(" that ti_am335x_tsc driver can not be build
in, and must be loaded as a module after the cape for TSC is loaded. That's
because I use "overlay-ed" cape for TSC. Even though it is set to be loaded
in uEnv.txt!
3) Big touch screen has bigger capacity, it results in permanent
"auto-touch" event generation, driving me nuts since LCD7 TS works nicely.
I have discovered, that adjusting delays in driver is the solution!!!
There are "open-delay", "sample-delay", "charging-delay" defined in
ti_am335x_tscad.h file. They have fundamental influence on this effect.
Someone has mentioned that "hardware issue" was observed as a few
"auto-touch" glitches. That is exactly this, just in case of a smaller TS,
it is not so evident.
So, concluding, now I'm focusing on adjusting delays. I'll let you know my
setting for this 10inch TS.
Regards,
Piotr
