Huion-Switch-Screen

AutoHotkey script for toggling pen mapping between multiple monitors.

The script implements this pen mapping function from the driver window BUT INSTEAD activated by a keyboard hotkey 🤩👍

This script adds hotkey functionality for switching pen mappings on buttonless Huion pen tablets, like the Kamvas 22 Plus. This feature is currently missing from the official Huion driver. 🤦‍♂️

The script functions like a game hack by injecting an integer value directly into the memory of a running process, specifically HuionTabletCore.exe. I used cheat engine https://www.cheatengine.org/ to find the memorypointers and offsets to set that value.

Since this is an AutoHotkey script, you can easily change it yourself and use a different hotkey or make one hotkey for each monitor, or whatever you like 😘

Installation:

• download and install autohotkey v1

• download both huionhack.ahk and classmemory.ahk and put them in the same folder, then run huionhack.ahk

• OR

• download the precompiled exe from the release section and use that instead (it precompiled with capslock as hotkey)

• I recommend running the script with administrator privileges.

• If you want to autostart eleveated apps at windows startup without prompting, i highly recommend to use the tool "skip UAC Prompt" https://www.sordum.org/16219/skip-uac-prompt-v1-2/
