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 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 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.
The following Intel I2C controllers are fully supported:
INT33C3– Haswell era
INT3433– Broadwell era
pci8086,9d63– Skylake era
pci8086,a161– Kaby Lake era
pci8086,9de9– Cannon Lake/Whiskey Lake era
pci8086,a36b– Coffee Lake era
pci8086,2e9– Comet Lake era
The following device classes are fully supported:
- I2C-HID devices
- ELAN devices
- FTE devices
Note that there is sometimes an overlap between device classes. For example, some ELAN devices may also be I2C-HID devices.
Please check the compatibility page on the VoodooI2C wiki to find out if your device is compatible. If it is not on the list but you still suspect VoodooI2C may work for you, contact us on our Gitter page.
