- # i2c_scanner
- Aiming to provide a more qmk friendly version of <https://playground.arduino.cc/Main/I2cScanner/>
- > This very simple ~~sketch~~ keymap scans the I2C-bus for devices. If a device is found, it is reported to the ~~Arduino serial monitor~~ console.
- ## Flashing
- Pick a target that is aligned to the MCU you want to test:
- ```console
- make handwired/onekey/elite_c:i2c_scanner:flash # also 32u4 + dfu bootloader
- make handwired/onekey/promicro:i2c_scanner:flash
- make handwired/onekey/teensy_2:i2c_scanner:flash
- # ChibiOS is currently 'best effort' and might not report accurate results
- make handwired/onekey/proton_c:i2c_scanner:flash
- ```
- others might work with additional configuration.
- ## Usage
- Output is viewable through a compatible tool <https://docs.qmk.fm/#/newbs_testing_debugging?id=debugging-tools>.
- You can change the wires, and plug-in I2C devices while the i2c_scanner is running.
- The output of the console will look like this:
- ```
- Listening:
- Scanning...
- I2C device found at address 0x20
- done
- ```
