- Swap HUB0/HUB1 addresses; they were the wrong way round. - Add DIR_* constants for all seven motors, with DIR_RIGHT_TRACK at -1. - Swap the right arm buttons: Cross raises, Triangle lowers. - Move struct Frame into the types block - the Arduino prototype generator needs it declared above the first function definition. - Pin core 2.0.17 in the header; 3.x will not build Legoino.
