Caution
Hardware & software only support the models of the touchpad mentioned above, untested touchpad models may be incompatible.
Use of such models can lead to driver failure or permanent hardware damage caused by short circuits!
Important
The pressure-sensitive touchpad promoted by Xiaomi merely replaced the traditional mechanical structure with a pressure-sensitive motor trigger, it is not a complete pressure-sensing recognition (there is no pressure-sensing feedback adjustment).
Recommand to use XiaoMi Goodix TouchPad.

Two fingers tap (equal to right click) can only trigger on laptop.
The triggering issue was caused by the missing of physical XY dimensions, and it has now been fixed.
To ensure the best compatibility among different touchpad devices, the receiver will not report the PHYSICAL coordinates in default. Some functions maybe unavailable.
If you ONLY use specific model touchpad, you can choose the model insdkconfigfrom2.4Gproject. For more details, please refer to "Setup & Configuration" section of the 2.4G receiver.Multi-Port HID compatibility design may not support on some old system, like Windows XP.
This was caused by a bug in the HID Descriptor I programmed, and it has now been fixed.
