i2c_scanner
Aiming to provide a more qmk friendly version of https://playground.arduino.cc/Main/I2cScanner/
This very simple
sketchkeymap scans the I2C-bus for devices. If a device is found, it is reported to theArduino serial monitorconsole.
Flashing
Pick a target that is aligned to the MCU you want to test:
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:
