Does anyone know how I can hook up a microphone to the hb? It doesn't matter if it notices different frequencies so long as it can tell me the volume of the sound. If anyone knows where I can buy the parts I need I would greatly appreciate it. (...) (25 years ago, 3-Nov-99, to lugnet.robotics.handyboard)

Hi all, Everything looks normal as far as I can tell. Able to download IC , lib_hb.icb, lib_hb.c and hbtest.c but nothing happens. I can exercise the hb functions individually using IC but hbtest.c does nothing. What could be the problem? TIA John (25 years ago, 3-Nov-99, to lugnet.robotics.handyboard)

I don't claim to be an expert on this, but here are my ideas. To get a clean HB up and running you need to do the following (assuming talkeree.s19 is larger than 256 bytes) 1) Start off by booting the HB into bootstrap mode. This makes the board (...)

Interesting discussion but it raises a few more questions. Are there any (bad) side effects when user code that is inserted in the ISR takes longer to execute than the 1 msec interrupt cycle. From experience it appears that the ISR runs on the next (...) (25 years ago, 2-Nov-99, to lugnet.robotics.handyboard)
