This is getting on my nerves and is killing me! I've been working on this for awhile now:

My BSII will just restart after doing the actions LookAroundYou and Aline
heres the code: www.geocities.com/name_here44/messenger.bs2.txt

Thanks in advance,
Mohammad.

    What type of Board are you using the BS2 with? Your power supply may be pulled low with you operating the 2 servos and other stuff at the same time and reseting the BS2.

    Im using the boe-bot
    edit on the program too. now it goes to the turn point then restarts

    This is a classic symptom of low battery. You aren't by any chance using rechargeable batteries?

    An alkaline battery gets 1.5 volts per cell, while a rechargeable (Ni-cd or Ni-mh) gets 1.2 volts per cell, when fully charged. 4 x 1.2 == 5 volts, which is close to the marginal edge of what the BS2 will run at. Any extra load (like a Servo activating) will reset the BS2.

    To detect this, put a:

    SEROUT 16, 16864, [noparse][[/noparse]"Did Reset", 13] at the start of your program. Then, every time it resets, you'll see the message on the 'debug' terminal.

    Sounds like a voltage drop to me if you have a anaolg volt meter you might see it happen.

    that's what I'm thinking now, so I'm asking for too much power right? how do I fix this?

    Another possibility could be a GOSUB stack overflow. You need to make sure that every GOSUB eventually results in a RETURN.

    It's always useful for you to post a circuit or at least describe what's connected to what.

    Sometimes it's not the average power drain, but the peaks that cause problems. Try connecting a 500uF or 1000uF 6V electrolytic capacitor across the 5V regulated supply to the Stamp.

    on page 252 of [noparse][[/noparse]link]http://www.parallax.com/dl/docs/books/edu/Roboticsv2_2.pdf[noparse][[/noparse]/link] + I have pizeospeaker hooked up on p4 and a Bicolor LED directly pluged in on p15 and p14 it said it took 5v so I didn't put a resistor

    Mike has a good point…Your main routine drops right into a subroutine causing a RETURN without GOSUB situation.

    What? Where? I checked that can you qoute that part?

    Thanks,
    Mohammad (so close to fixing it!)

    Just before the "Travel:" label, there is a RETURN and there's no corresponding GOSUB. Maybe you meant to put a STOP or a GOTO Main statement?

    And that is also different from the original code you posted which didn’t have that RETURN and instead fell into the subroutine below which causes the same problem.

    well that script didn't work so I'm gana try something else this seems quite pointless.
