VF61 WinCE mouse issue

I have a problem with mouse when I read data from RTC by I2C1 every second.
After a few seconds later when I moved mouse up and down the mouse pointer jump to the top corner of the screen.

It is any connection between I2C1 and mouse driver?

Hi,

No mouse and I2C are not connect. What version of OS are you using?
Do you have some registry settings? Can you try with empty registry just read I2C1 and do nothing else.

Hi,

I have FTDI chip connected but I reset registers and unplug touch screen I think was faulty then mouse is working fine.

Thank you.
