I think I've read every post with similar errors and haven't found a resolution yet. I've flipped the switch to Arduino and tried every other simple troubleshooting step. I'm stuck. After trying to upload OpneCat.ino The Arduino code window give at `Error compiling for board Arduino Uno` error. I've checked the board is set to Arduino Uno using a NyBoard V1_0 The Serial Monitor window perpetually shows; * Change "#define NyBoard_V*_*" in OpenCat.h according to your NyBoard version! * OpenCat Writing Constants to EEPROM... Reset joint calibration? (Y/n) Thanks for your help! I'm lost 🙃
