| Maarten -- Quickly I can make the guess that your local copy of PCODE_HB.S19 is corrupt. The fact that PCODER22.S19 works indicates there's nothing wrong with your board. Try re-downloading PCODE_HB.S19 from the web site? Fred In your message you (...) (27 years ago, 5-Feb-98, to lugnet.robotics.handyboard)

Sure, there's no reason you could set it up to use PD4, PD5, and TIC3 for a 2nd sonar. you might be able to get away with some signal multiplexing, assuming you're only firing one sonar at a time. i could see the BINH being no problem.
