TXT 4.0 controller using ROBOProCoding & I2C

To connect the ftcSoundBar via i²c-bus, you need 6-to-pin-adapter and two 1:1 ribbon cables between TXT 4.0 extention port and ftcSoundBar's I2C interface at the right side.

  • Checkout RoboProCoding folder
  • Try ftcSoundBar.ft to play some songs.

The getter functions like getVolume are not stable, due to some I2C bus limitations in the used expressif framework. As a workaoud, you could store the last transferred value in a global variable and use it instead of calling the getter functions.
