Anyway, I can control mine across the house (15/20 meters distance). Also, one thing I noticed is that the error correction (...) (26 years ago, 3-Jan-99, to lugnet.robotics)

| | | | | (...) I remembered once something Dave told me: AGC is unsafe if used inside NQCC. His words: ---...--- The AGC() macro is the only one to use a 5 bit selector code (0x10). For many instructions (such as tests), the selector code must be fit into 4 (...) (26 years ago, 3-Jan-99, to lugnet.robotics)

Values returned by function AGC: 0 m: 50 - 110 1 m: 600 - 650 The values may vary a bit, but I think that the tower increases the power the further away the CM gets. -Ole -- Did you (...)
