Resetting BS2 on BOE using commands.

Vincenzo1309

Dear all,

I am now using a BOE with BS2 chip on it. I know that pin 22 is the Reset pin for BS2, and should I need to reset the BS2, I just need to press the Reset button on the board.

Now since the board is on my mobile robot, I would like to reset the BOE/BS2 (or whole program) by just using commands without having to go to my robot and reset it. Is there such command?

Kindly advise.

There is no way to reset the BS2 with a software statement, but there's nothing "hidden" to reset. A hardware reset causes all the variables to be reset to zero including the I/O registers (DIRS, OUTS) as described in the Stamp Basic Manual. Your program can do that as part of its initialization so that all you would need to do is to GOTO the beginning of the initialization routine.

Can't a stamp pin be used to drive the reset pin low and force a reset?

Yes it can.· Take care.

I love Chris's 3 word replies [noparse]:)[/noparse]

So it seems you can do what you want Vincezo1309, you just need to dedicate a stamp pin to it.

I'd still use a resistor (1k maybe?) between the stamp pin and the reset pin to prevent any possible problems.

Connecting it might be a pain... you may be able to get the lead of the resistor (or a very small wire) in the stamp socket beside the leg of the stamp if your VERY careful... remember,
those stamp pins are very fragile!



Note: I've never done this so I may be totally wrong about everything... I'm just guessing based on what Chris said.
