Hi Jan, I tested it and it's veeeeery slooo...oooww. Elektuur writes that the interface could be an extention of the RCX for more sensors you may use for your roboter. The software is written for NQC and uses some sensor functions to realize the i2c (...) (23 years ago, 15-Jun-02, to lugnet.robotics.rcx)
