Subject: [alt-beam] please HELP....5 motor walker
Dear List;
Sorry to butt in like this..since some discussion/debate is
going on right now, but I have a few question to ask and need help.OK,
here goes, firstly I got a problem of my Mcore resetting after I
connect the driver/switching circuit...ok, i know some will say, it's
the electrical noise prob again!BUT, I am using 2 power supply( 1
supply is a REGULATED power supply for the mcore and the other is
UNREGULATED for the driver circuit).Does this different power supply
might cause the prob??Or izzit just the different voltage I am using
for each power supply?(3V and 4.5v).
One more thing is, I noticed that the output LED nearest to
the PNC will sort of dim alittle when I switch on the power.Does this
contribute to the reset problem?I never have that problem when the
mcore is not connected to the driver/switching circuit..check all the
wire alot of time and I am using 5 RC servos motors.Any
comments??Please help.BTW, the design is CHIU's...hmm...CHIU...any
solution on my 5 motors walker??Could it be...ARRGHH..static?
Thanks for reading this..
Victor
