Re: [Gumstix-users] Alternative LCDs & touchscreens

Yes I've run those programs.  ts_print, ts_print_raw, etc are all installed.  

On any typical phone I've used (iPhone, Droid etc), merely resting my finger on 
the screen results in a touch.
On the 4.3" LCD with the chestnut kit you definitely have to "apply pressure" 
with your finger to get a result from ts_print or ts_print_raw.

Maybe I'm just spoiled by capacitive screens?

Have you tried using any of the ts_* programs to see what they give you? I 
remember when I was troubleshooting touchscreen and driver operation I would use 
ts_print (or maybe it was ts_print_raw?), which would basically report the X:Y 
position and Z pressure of a touch event. With that you might be able to see if 
what you would consider reasonable touch pressure is registering with the 
driver. If you don't have ts_print on your gumstix I think it comes in the 
tslib-tests package.
