QMK Hardware Drivers

QMK is used on a lot of different hardware. While support for the most common MCU's and matrix configurations is built-in there are a number of drivers that can be added to a keyboard to support additional hardware. Examples include mice and other pointing devices, i/o expanders for split keyboards, bluetooth modules, and LCD, OLED, and TFT screens.

Available Drivers

ProMicro (AVR Only)

Support for addressing pins on the ProMicro by their Arduino name rather than their AVR name. This needs to be better documented, if you are trying to do this and reading the code doesn't help please open an issue and we can help you through the process.

SSD1306 (AVR Only)

Support for SSD1306 based OLED displays. This needs to be better documented, if you are trying to do this and reading the code doesn't help please open an issue and we can help you through the process.

uGFX

You can make use of uGFX within QMK to drive character and graphic LCD's, LED arrays, OLED, TFT, and other display technologies. This needs to be better documented, if you are trying to do this and reading the code doesn't help please open an issue and we can help you through the process.

WS2812 (AVR Only)

Support for WS2811/WS2812{a,b,c} LED's. For more information see the RGB Light page.

IS31FL3731

Support for up to 2 drivers. Each driver impliments 2 charlieplex matrices to individually address LEDs using I2C. This allows up to 144 same color LEDs or 32 RGB LEDs. For more information on how to setup the driver see the RGB Matrix page.

IS31FL3733

Support for up to a single driver with room for expansion. Each driver can control 192 individual LEDs or 64 RGB LEDs. For more information on how to setup the driver see the RGB Matrix page.
