Making multiple chips with OEM

Can I program multiple chips on the BS2 OEM and put them into a circut without having to buy whole stamps?· What would I need to get a chip to work outside of a stamp or OEM board?

    You can use an OEM BASIC Stamp as a programming platform for the EEPROM, then move it to your won circuit (I've done this). You should download and study the schematic for the OEM BASIC Stamp -- it will tell you what you need to know.

    Im not sure what Im looking for in the scematic... First question is what is a WON circut?

    I think he meant your own circuit...lol

    So basically I need my own circut with everything on the scematic?

    No, youll need your own circuit (or board or whatever) but you dont need "everything" on the OEM board.

    I beleive all youll need is the interpretor, eeprom, resonator, and "maybe" some resitors/capacitors.

    I think you can ommit the transistors, the resitors, the voltage regulator (as long as youre using something like a 9v battery to power your circuit), the serial connector, the connector pins, the 10 uf cap, and the .1 caps.

    I beleive the only reason the caps, resitors voltage reg. etc. are their is for the serial connection, and if you're going to be using a wall type power supply.

    You will need everything on the OEM board if you are going to build an operating Stamp.· Without the regulator, the 9V battery woiuld do nothing.· And without the transistors, caps and resistors you won't be able to program it.· If they weren't necessary, Parallax wouldn't have them there.

    I beleive he is just wanting to program the chips using that kit then put the chips into his own circuit, not build a whole OEM stamp. In which case you wouldnt need anything associated with programing it.

    I just noticed though, I said you wont need the voltage reg., you will need it. While I was typing that I was thinking of a bs2 IC, it has the voltage regulator built in.

    He could start with an OEM BASIC Stamp, program the EE, remove it, then put it into an EE duplicator.

    And yes, one could build an EE duplicator using a BASIC Stamp. I've posted a bunch of I2C routines that will run on and BASIC Stamp (use built-in commands if using the BS2p or BS2pe).

    Even if he didn't want to build a duplicator, or use one...He could program the chips using the BS2 OEM board, remove them and put them into his circuit.· I would recommend a ZIF socket for such an endeavor though.

    Yes get a zero insert force socket, They may be a little expensive but multiple insertion/removal with regular sockets tends to lead to bent or sometimes broke pins, unless youre carefull that is.

    So could this

    be used as a slave chip?

    What do you mean by slave chip ?
    If you want to know if it will run the code from the EEPROM, then no it won't.
    You need to get a processor that is already programmed with the interpreter.

    So the little chip is the EEPROM and I need this with it?
