 | | RE: IR problems

| Hmmm The blip and LCD clearing, while useful for debugging may be messing things up. The characters are coming in way faster than the blip time, so you may not be reading the buffer fast enough. I would put code at the end of getHeader that (...) (21 years ago, 24-Jan-04, to lugnet.robotics.rcx.pbforth)

I might have followed the wrong track but I got to this 'test program' trying to solve the problem I have in my 'real' program: I'm writing a PbForth version of the Trailerbot (Luis Villa, Extreme Mindstorms). The (...) (21 years ago, 28-Jan-04, to lugnet.robotics.rcx.pbforth)

The code I've been testing and the examples you have help me with all work if I place the light sensor about 2 mm from the IR transmitter. At about 2cm it no longer works at all. I have (...)

After some apparently common problems, I managed to compile the h8300 programs and compile legOS 0.2.2. The demos work as (...) (25 years ago, 22-Nov-99, to lugnet.robotics.rcx.legos)
