Which Basic Stamp, if any?

Well, heres the project im working on.

I want to have four sensors reading 3 different pressures and one
temperature simultaneously. I want to then display those readings on
four different seven segment displays.

Heres what im thinking so far...

(4) sensors 0-5 volt

(4) a/d converters (8 bit)

(4) 4 digit 7-segment display driver

(4) 4 digit 7 segment displays

(1) basic stamp

my thinking is i can input the 8 bits into the stamp apply the
appropriate math then output the number in appropriate form (psi,
deg, etc)

I guess my question would be,

1. can the stamp do what im asking of it
2. which stamp would be best for my application

thanks

Nick

    I believe the BS2p40 could handle your requirements. Also for your display
    for each Set of values to display you would then need a Maxim7219 - 7
    Segment display driver and the appropriate Common Cathode 7 segment
    Displays. as far as pressure and temperature sensors go i believe i can't
    help you there. Good luck with your project.

    Depending on what your application is, you can probably use any of the
    BS2 family. The BS2p and BS2pe offer more language features -- the BS2p
    is the fastest.

    * Use an ADC0834 (8-bit resolution, four channels) or MAX1270 (10-bit,
    four channels) to handle your analog inputs.

    * The MAX7219 will drive up to eight 7-segment displays.

    * Check Digi-Key or other online sources for displays that meet your
    needs.

    Thanks for the help guys! I havent worked with stamp in about 4
    years, so its gonna be interesting! I guess we'll see how it goes.

    Hi,

    I think any of the Stamps could do that, it depends on what you mean
    by "appropriate math", if the outputs of your sensors are non-linear
    then things could get a little difficult but not impossible. As Jon
    suggested, use one MAX1270 A/D converter which has 8 channels. I've
    used them with Stamps with great success. Although 7-seg LED displays
    are cool, I personally would drop that idea in favor a backlit serial
    LCD and a pushbutton that would allow you to scroll through the
    sensor readings. The MAX7219 is a cool part but IMO, that would make
    things alot more difficult unless your project has a specific
    requirement for the LED displays. Regards,

    -Dave

    I like the idea of the lcd screen as well but, this will be in my car
    and its kind of an on-the-fly type of reading. So i need something
    big and easy to read so i can monitor my engine. The 7 seg displays
    will be a pain to wire but i think it will give the best display for
    the job, unless anyone has a better suggestion.

    BTW my definition of appropriate math is: "I havent thought this far
    ahead yet"

    Take a look at the Motorola MC14489 Multi-Character LED Display/Lamp
    Driver. It should simplify your interface to a 7-segment LED display.
    I'm currently experimenting with this part using a PIC 16F877
    programmed in assembly language. I am designing a somewhat general
    purpose board with a display range of -199 to +199, three decimal
    points and four general purpose LEDs.

    Maybe a VFD (VACUUM FLUORESCENT DISPLAY) will fit the bill.
    Controled simular to an LCD but bright characters like a LED.

    Here's a few:

    I like the LCD idea better. Also sold by EarthLCD is the 8x24 LCD panel.
    this could very well display each of your applications on one lcd so you
    dont have to do anything. its 8 lines by 24 characters long. i think this
    is ideal for your application. you should check it out with the link provided.

    http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2786461146&category=162

    i also have one available for sale if anyone is interested. This panel is
    just like the scott edwards panel. for your application simply send this to
    the LCD

    SEROUT 0,N9600,[noparse][[/noparse]"Valve 1 PSI is ",DEC psi,] ---- and this would display on
    the top line "Valve 1 PSI is 10" assuming 10 is stored in the variable psi

    I think this is ideal for your APP, Futhermore its possible to add a
    backlight to this LCD for night time use.

    Gary D

    The Noritake VFDs are great, and really easy to use. The serial ones are
    fast and use one I/O.

    After some searching i found this display which seems to fit my

    I really dont know how to operate it but ill figure that out

    That'll work. The datasheet says the TX/RX lines are both TTL and RS-
    232 compatible so you shouldn't need a level shifter. I don't know
    where to buy one though, probably best to contact the manufacturer.
    Let us know when you locate a supplier, I might buy one myself.
