Implement two vibration feedbacks when pressing the touchpad again

[hetaorens]

Thank you for the terrific work! I have been using this driver on archlinux for a long time. By adjusting the sensitivity of the touchpad and using some software such as Touchegg, I can achieve almost the same effect as MacOS. However, there is a very useful feature on MacOS which is the second-stage feedback of pressing hard. In this way, the advantages of the trackpad can be enhanced to a higher dimension. I want to check the principle of the touchpad driver through IORegistry Explorer on MacOs, but I still can’t understand how MacOS achieves two vibrations. However, since pressure detection is implemented in this driver, it should be able to quickly achieve two or more vibrations. Vibration feedback to reach a higher level.

Hi @hetaorens , Thank you for your nice feedback. I think what you want is "force touch". There is some information in this issue:

https://github.com/mwyborski/Linux-Magic-Trackpad-2-Driver/issues/3

I haven't looked at the current driver in the kernel and can't say anything if this feature was added or not. But if you want to try to implement it, I think you might find enough information in the mentioned issue to get you started.
