Hi all,
I'm at stage 7.2.2. of assembly, and I have partial failure of the digital
ins, when I type "testdigitals();" at the ic prompt, (After pressing start,
and stop) I get on the handyboard screen 9 gently flashing zeros, nothing
wrong so far then!    The far right digital (Labled 7 works fine, and
changes to a 1 when tested, but if I try any of the other digitals I get
"111111110" shown on the screen, does this mean RP1 is in backward? Or is
there another problem? Thanks in advance!

(...) Sounds like the inputs are shorted together somehow. Check your soldering in this area for bridges. Best, Duncan (25 years ago, 8-Jun-99, to lugnet.robotics.handyboard)
