hi, looks like i cannot find the shell script (as11_icb) that assembles an asm file and packs it into an icb file. in theory it should be with the pcode source distribution but it doesn't seem to be there. i'm sure i am missing something. could (...)

You can't use the one in the library I wrote? (its available on the iccll web site) Basically msleep spin locks on the timer waiting for systicks to increment the appropriate number of milliseconds. If you aren't using my code you can do the same (...) (26 years ago, 20-Feb-99, to lugnet.robotics.handyboard)

I have a HB w/exp brd and a PortMaster (a stock board with a 68HC11E1, 68HC24 port expansion and 32k ram). I'm programming the HB with IC3.2 and the PortMaster with ICC11v5.

I managed to speak with one of Linx's applications engineers- He said that a couple of the guys over there are using the Linx modules to communicate with HC11's, so interfacing the kit with the handyboard shouldn't be much of a problem.

I believe that you will find that most photo transistors are sensitive to a very narrow range of frequencies, mostly in the IR range. OTOH a photo resistor is sensitive to a much wider range of frequencies and may be usable with a (colour) filter. (...) (26 years ago, 19-Feb-99, to lugnet.robotics.handyboard)
