BS1 vs. BS2, will this work with a BS1?

Hello, I'm working on a rocket related project, and was hoping I could use a BS1 due to its smaller size (but I'm slighly more familiar with the BS2).

The BS1 will only need to do a few SIMPLE functions:
1) read values from a 12-bit ADC (LTC1298)
2) open and close a transistor
3) operate 1 or 2 LEDs
4) store a few data values from the 12-bit ADC (at least one data value, but the more the merrier).

Will the BS1 be able to handle these tasks?

Thanks

    Evergreen,

    Yes, the BS1-IC can do this task.

    1) Example code is here - http://www.parallax.com/dl/docs/prod/appkit/ltc1298.pdf - three I/O pins required.
    2) HIGH and LOW - one I/O pin
    3) HIGH and LOW - one or two I/O pins
    4) READ and WRITE - limited memory 256 bytes, but easy access to the EEPROM - no I/O pins

    Depending on how much data you want to store (4) everything seems quite appropriate for a BS1-IC.

    By the way, be sure to see our Near Space articles since you are interested in rocketry. You can find them at the bottom of this page: http://www.parallax.com/html_pages/resources/custapps/app_nearspace.asp.

    Which BASIC Stamp are you going to use?· You have another thread asking about doing the same thing for the BS2.

    I'm not sure yet. I might just end up with the BS1 because of its small size.

    I have another question (should I put this as a new thread?). What's the difference between a BS1 and a BASIC Stamp Rev. Dx? They appear to have the same specs.

    Thanks,
    Matt

    Matt,

    Just the package format. One is a SIP and another is a small PCB with prototype area. Your choice!

    Okay, sounds good!

    Are any of the holes in the Rev. Dx board connected? Or are they all independent of each other (if so, does that mean I have to strictly use wire wrap?)?

    If you look carefully you can see that the first column of holes is connected (matches the labels to the left of the header).

    Hello!
    Overworked and underpaid consultant's opinion here:
    That PCB that the Stamp Dx wears, isn't it roughly the same form factor as the one for the BS1's carrier board? (The simple one not the complex one.)

    They are about the same size, but you can see that the carrier has more prototyping holes (since the BS1 parts are on the BS1-IC).
