Touch panel resolution and calibration - New Device

[CollinJoseph]

Hello,

I just have a few questions regarding setting up a new firmware.

1. Copied the driver from Windows onto my Linux computer.
2. Converted the sys file into firmware using
   tools/scanwindrv SileadTouch.sys
3. Tested the firmware with gslx680_ts_acpi and silead_ts

It is working but not completed. My touch was all over the place. I reduced it by swapping the axis and mirroring the y-axis. Still, it is not at a state where I can use it for simple things. I believe my current issue is touch panel resolution and calibration.

1. How do you figure out the touch panel resolution? Is it by testing random values until something works or is there another way like reverse engineering the firmware? or some other way?
2. If I get the touch panel resolution would I do an additional calibration ( I asking this question based on this)

Thank you
