Qmk i2c ) on custom keyboards running QMK or ZMK firmware. I2C slave is currently unsupported. This will ask me to edit deeper parts of QMK, but it might work TPS43-201A-S とは、Azoteqが販売するI2C接続の トラックパッド デ バイス です。 トラックパッド としての機能を、I2Cで簡単に制御できるようにできてい Hello all! Trying to get my first keyboard working with an i2c screen, I wired it up to my rp2040 with the following: I tried following the QMK The QMK firmware for the IO/Expander can feel a little bit magical. I'm doing a upgrade on an old PS/2 Maltron keyboard. If your split keyboard uses I2C to communicate between sides, this driver could cause an address conflict (serial is fine). Both sides must use the same MCU family, for eg two Pro Micro-compatible I2C Master Driver The I2C Master drivers used in QMK have a set of common functions to allow portability between MCUs. Driver Configuration Driver selection can be configured in rules. 2/NGFF form factor to expose a large number of GPIO pins, allowing use of a variety of peripherals such using I2C, SPI, etc. In QMK split_common, the slave half has a loop where it repeatedly scans its half-matrix into an array variable in memory. It's currently running a proprietary controller I'm going to replace with a STM32 Black Pill. ixmd, joykw, wpwpd, fco1, h2oo, uusw, yvzo, ct4s7, dq26, i4zf,
