Pi Pico Puts Bluetooth Keyboards on the I2C Bus

Pi Pico W with bt2i2c firmware routes Bluetooth keyboard input to I2C bus using address 0x1F. Keystrokes from standard Bluetooth keyboards appear as if from a BlackBerry BBQ20/BBQ10 device. Users can integrate with existing I2C code for sensors and displays. The setup allows microcontroller projects to use familiar keyboard input without additional wiring or complex drivers.
