Dear handyboard users,
I've been reading your archive and I've found many helpful
hints. Thanks for all of your passive help.
I am building my handyboard and have run up against a hitch.
Maybe my situation sounds familiar to someone, or maybe
someone has some ideas about what I can try next.
I've built the Serial Interface / Battery Charger Board,
but I can't get the green light (LED12G) to light up when
I run dl. I tested the circuit incrementally as in Fred's
instructions and everything tested o.k. to this point.
Specifically, the voltages described were close to the
ones that I measured. Touching pin 6 of the MAX232 to pin 2
of J9 causes the green light to come on.
When I run:
dl pcode_hb.s19
the green light does not light up. I have a breakout
box connected between my PC (486/33 running either
Linux or DOS, same behavior). So, I know that it is
communicating on the right port. Pin 3 on the
breakout box flickers as dl runs. Pin 2 does not
flicker.
I've tested the connections pretty well and I don't
believe it's a soldering problem. I've also looked at
the components to make sure that they are installed
correctly.
Any hints are appreciated. If there are some other
tests for voltages that I could perform, that would
be helpful, I think.
