 | | 68H11 on HandyBoard?
|
|
Trying to find all components needed to build a HandyBoard, I have a quite some troubles finding the 68HC11, which is quite vital, I'd say ;-). I now found a place where they sell a lot of IC's, but - of course - not the 68HC11. but they DO sell a (...) (27 years ago, 5-Jan-98, to lugnet.robotics.handyboard)

(...) If you're just interested in sample code, check out: ftp://ftp.cmf.nrl.na...lib.tar.gz Code to talk the Dallas One-Wire protocol is included. Also included is sample C code that implements the bus discovery protocol. It's actually pretty easy (...) (27 years ago, 5-Jan-98, to lugnet.robotics.handyboard)

Seems to work well in the 10 minues of testing I've just done. :) Let me know if anyone has problems with this: *Brian Schmalz /* Function to enable SPI port as digital I/O */ /* First you must (...)

Thanks David for a nice explanation of how to add I/O using shift registers. Let us not all forget that the HB does have two uncommitted digital output ASIDE from the four SPI pins: PA7 (a bidirectional pin which is marked as digital input #9) and (...)
