Hi:

I am using tslib with /ti-sdk-am335x-evm-05.06.00.00/board-support/linux-3.2.0-psp05.06.00.00

And,  with ts_print_raw I found that with same external pressure on different position on touchscreen will get different value of pressure (variance maybe up to 250),

Do you guys ever encounter such problems ?

Thanks
