It is the best performing detector I have found so far. (26 years ago, 4-Apr-99, to lugnet.robotics.rcx.pbforth)

| Regarding your program. Try sending 0s, not xs, i.e.: char *buffer = "\0\0\0\0\0"; Zeros are coded with the IR on 91% of the time, while xs are coded with the IR on only 45% of the time, neglecting the modulation, which cuts that all down by half.
