 GSLx680 I2C touch controller，only one point，not 10 point

[Mario Holzinger]

Hi!

I face the same issue but didn't find the time to investigate further due to the fact that I'm not the creator of the source code.

https://github.com/onitake/gslx680-acpi

I spend a few days to get it basically working with my self created firmware and after testing in ubuntu & android (each of them needs additional calibration) decided to share my investigation so everyone sees that we are able to use this controller also on linux but we need to improve it if we want more.

feel free to improve the work (fix issues) and share the solution in form of patches to the community

May I ask you to explain what device you are trying to get running?

What kind of Firmware did you already have (Windows 10 firmware, Android)

if possible pleas provide my your original firmware that was shipped with your device and I will try to get a working one out of the tools and give you and the rest a how to to get to a firmware that can be used with the code

please see here，https://github.com/onitake/gsl-firmware/issues/6  ，can't get Precise and accurate parameters ，-w -h parameter
