VoodooI2C Help and Support

7 posts in this topic

Recommended Posts

This thread is intended for users of VoodooI2C to get support for using the kext on their system.

 

What is VoodooI2C?

 

VoodooI2C is a project consisting of macOS kernel extensions that add support for I2C bus devices. The project is split into two main components: the core extension and various other satellite extensions.

 

The Core

The core is the VoodooI2C.kext kernel extension. This kext is intended to be installed by anyone whose computer requires some form of I2C support. It consists of I2C controller drivers and is responsible for publishing device nubs to the IOService plane.

 

The Satellites

The satellites are a collection of various kernel extensions that implement support for a specific type of I2C device. An example of a satellite kext is VoodooI2CHID.kext which adds support for I2C-HID devices. Usually a user will install one satellite kext per class of I2C device.

 

What can I use VoodooI2C for?

 

The most common devices that are compatible with VoodooI2C are I2C-HID devices such as Precision Trackpads and Touchscreens. If you have an I2C trackpad or touchscreen, chances are it will work with this driver. It is also possible to use VoodooI2C to get multitouch on USB devices but this is experimental.

 

How do I install VoodooI2C?

 

All installation instructions can be found here: https://voodooi2c.github.io/#Installation/Installation

The patches are in the linked repository (which comes from https://github.com/alexandred/VoodooI2C-Patches )

 

Moreover, most Skylake+ users will require manually applying a GPIO pinning patch for which they need to follow the GPIO pinning guide. It is not possible to create an all-encompassing patch for this particular step so there exists no "patch" for it.

I have successfully enabled the ELAN 1300 Touchpad on the Asus UX430UA with this patch

into device label ETPD insert begin

Name (SBFG, ResourceTemplate ()\n
    {\n
        GpioInt (Level, ActiveLow, ExclusiveAndWake, PullDefault, 0x0000,\n
            "\\_SB.PCI0.GPI0", 0x00, ResourceConsumer, ,\n
            )\n
            {   // Pin list\n
                0x55\n
            }\n
    })\n
    
end;

The device is root-pinned. Kext installed: VoodooI2C.kext and VoodooI2CHID.kext
