The encoding is straight serial, but inverted - a pulse of light indicates a zero or a low voltage on a (...) (25 years ago, 18-Sep-99, to lugnet.robotics.rcx)

| Hi All. Is there a way to set the IR transmitter to something like 'long range mode'? I would like to have a more powerful beam for proximity detection. I've tried lnp_logical_range(1), doesn't seem to make a difference. The problem is that I don't (...) (25 years ago, 2-Nov-99, to lugnet.robotics.rcx.legos)
