AD7877 Linux Driver Support.

Hi ..

we are using AD7877 as the touch screen controller IC in point of sale application;

The processor is i.MX6SL; we have used the linux driver for AD7877 given in ADI website.

We are observing few issue in the application-

1. we are unable to draw the signature/any image while writing fast on the touch screen.

Please find the attached image for clarity.



2. second issue is that if we press any ikon through touch screen for example "Print" the selected content is getting printed two times...  looks like the function is getting invoked two times...

Pls advise with your inputs...
