PIC vs. Basic Stamp

What's the advantages of using a BS2 over a "raw" PIC? Ok, I know,
some of the advantages are obvious, but I'd like to see your list.

To take the programming variable out of the equation, let's assume you
were programming the "raw" PIC in PicBasic.

Specificaly, what could a decent programmer do with a BS2 that he/she
couldn't do with a PIC/UART combo?

Thanks

    Biggest advantage the PIC has over the Stamp is cost.

    First on my list is

    THIS LIST !!!

    far and away the best feature.

    #2 ease of programming.

    when you program the BS2, you are trouble shooting hardware 99% of
    the time. in other micro's, you are not sure. and you can spend
    (insert time here,minutes, hours, DAYS!) on trouble shooting a simple
    problem.

    #3 Onboard ADC
    #4 Onboard PWM

    #5 cost , the problms is that, although the PIC is lot's cheaper, it
    costs you pleanty to get there.

    $250.00 for PICBasicPro
    $100.00 for a high quaity programmer

    If you are doing 5 parts, you are better off with a BS2 for cost
    alone.

    #6 speed.

    #7 simplicity - BS2 has an onboard oscilator and onboard voltage
    regulator.

    #8 Versitility, you can get an 8 pin PIC for a very simple project.
    say a doggie door. monitor pet collar, open/close door. or a 40
    pin multi ADC behemouth.

    Like anything else, there are trade-offs in determining the "best".

    The Stamp has a low startup cost (all you *really* need to buy is a
    stamp itself). It is very easy to program/reprogram. The programming
    language is both easy to understand and based on a language that many
    people are at least somewhat familiar with.

    Well, there are dozens of different PICs. Depending on which you
    choose, you might gain or lose I/O pins, math functions, external
    interface options (I2C, 1-Wire, X-10, etc), execution speed, program
    size, etc.

    Generally speaking, I believe the Stamp is not cost-effective for use in
    a production product run of more than a handful of units. The Stamp is,
    however, very appropriate for custom projects/products, rapid
    development schedules, hobbyist/amateur use, robotics use, etc.

    I think that what it comes down to is a tradeoff of learning curve and
    ease of implementation vs. raw per-part cost.

    I've recently done a couple of custom automotive projects that are based
    on BS2's and/or BS2SX's. I could have used a PIC as the heart of these
    projects, but the stamp was just so much quicker and easier to develop
    on. Additionally, I can re-program the devices in the field much
    quicker/easier than I could with a PIC.

    Thanks for the responses! Pretty much what I expected, but I forgot
    about on-board ADC and PWM - or at least the fact that ADC is easier
    with a stamp.

    Hello,
    I'm a user of BSII and PIC (with PicBasic Pro). My first micro was a
    BSII. Nowaday I use the BSII for developening becuase of simplicity at the
    time to program, and debug (which is really a big help!). But as I use
    PicBasic Pro, I can optimize my application very much! PICs are (for example
    I use a 16F74) faster than Stamps (Real 20MHz vs. 20MHz but running an
    interpreter), and some PIC has more pins (my F74 has 22 I/O) which include
    Hardware USART, I2C Slave mode, 5 ADC 8bits, 11 Interrupts. And this is very
    simple to use with PBasic. But I still prefered my BSII, because of the
    reasons other users explain. And I don't have just one Stamp, I have 2 BSII
    and 1 BSIIp24. And I'm thinking of buying a Javelin Stamp.

    Well, I didn't say it was easier or better.
    actually we often use a TLC2543 11 channel 12 bit ADC for the
    expanded channels and also the higher resolution.

    OK, but the PIC16C77x includes 12-bit, multichannel A/D, but I don't
    have it working yet [noparse]:)[/noparse] .

    This list is great, but the piclist is equally impressive. It has high
    traffic and has massive searchable archives. See http://www.piclist.com for
    more info. I find the stamp list more receptive to code questions, but that
    could be because most pic programming questions can be answered by searching
    the archives. Also, while I don't use pic basic, I haven't noticed extensive
    discussion of the language on the piclist. Best to see for yourself though.

    Some use Stamps to work out ideas quickly and effectively, then go to Pic to
    save a few bucks on a finished product. The pic programmer pays for itself
    after two or three projects. IMHO both are awesome.

    I'd pic - er - pick - the Stamp over a PIC any day.

    Easy to use, from all levels - beginner to advanced.

    The Stamp is used, after all, in some impressive industrial applications.

    I'll have to agree with you Nick, both "Tools" are effective. The Stamp is
    great for
    getting the idea out quickly, and depending on what PIC compiler you use,
    some will
    generate assembly source code from your basic source code that can greatly
    reduce the
    learning curve, if/when you decide to move on to doing purely PIC
    programming or simply
    a hybrid cross-platform style of programming. I personally enjoy
    programming in assembly
    so this doesn't bother me to much. There are ways to structure your
    programming style
    in ANY language assembly included, that allow you to compartmentalize your
    code into
    specific functions that can make a language such as assembly seem like a
    high level
    programming platform.

    Cost and speed are what I found. PIC Chips from what I have found are
    $10 USD or less, the Stamps from what I found are $30USD and up.
    I do not know the exact figures but PIC chips do things a lot faster
    then Stamps.

    A couple more thoughts from me [noparse]:)[/noparse]

    1) Speed is often, but not always important. I've rarely ever said of
    my stamp "I wish this were faster", I've also never really noticed an
    observable speed improvement on the projects that I've migrated from
    Stamps to PICs (granted, these have been few).

    2) To play a bit on your statement "...PIC chips do things a lot faster
    then Stamps"
    I would have to say that for just about any beginner to
    microcontrollers, or anyone doing a 1-off project, one thing that the
    PICs *don't* do faster is lend themselves to a shortened development
    cycle.

    I've used a lot of different PIC tools and programmers, and I still
    truly believe that the overall Stamp tools from Parallax (programmer,
    debug options, carrier boards, programming resources, etc) make for a
    better and cheaper development environment when you're starting from
    scratch.

    I agree with everything said, So start with the stamp you can't
    go wrong, then step up to a pic if needed, you will use the stamp
    even after going to pics.

    I agree with Brian...I'm a little old school, and I used to design my
    controllers around a Z80, EPROM, SRAM, PIA, and other I/O chips as
    needed...Development of controllers was a bit tedious, to say the
    least. Stamps make things ALOT easier, and in most of the control
    applications I have seen, the Stamp is more than adequate in terms of
    speed.

    Ah yes, one of the simple demonstrative answers to the question.

    on another note, I prefer the Flash units.

    A cute comment, but the demonstrative point is that highest capabilities
    appear first in PICs before they appear in Stamps -- current example
    being 12-bit converters, and they aren't yet available in Microchip
    Flash units.

    Cute yes, but the true PIC has the hardware on chip. Keeps the PCB
    real estate down and I'd bet dollars to donuts the power
    cconsumption, and a speed benny. As opposed to a I2C, or other off
    chip ADC. (ok the off chip option give one the custom tayloring for
    resolution, channels and sampling rates)

    Personally I love both the Stamps and PICs. Buy a stamp and your
    done in a few hours with your project

    I am tired of hearing people complain about the cost of stamps. This
    is a circuit board assembly with additional features, that is being
    compared against the cost of a PIC chip. What a lot of people may not
    realize, is that once you have a prototype going using the DIP
    packaged Stamp. You can buy just the uController with PBASIC
    programmed into it and put onto your own board for <$10 depending on
    qty. ~$7 for 50 for Ubicom SX48 with PBASIC. (Ubicom SX48 is used in
    BS2P)

    I have successfully used these parts in two fiber-optic controller
    products. (These are products, not projects.)

    Time to working prototype for these < six weeks. Used the Parallax
    development board to breadboard the control circuits and develop code
    before the schematic was finalized and while the board was laid-out,
    fabricated, and assembled. As soon as assembled boards came in,
    PBASIC code was ready to go.

    There are only a few things to be careful about.
    1. Use the same resonator as the stamp board. (Available from
    Parallax)
    2. Attach an EEPROM for your code that is compatible with that on the
    stamp board. (Available from Parallax)
    3. Bring out the proper pins for serial programming, TX,RX, & ATN.
    The reset is needed to signal PBASIC for downloading code.
    4. Make a little RS-232 cable dongle that will convert signals to TTL
    level and echo back characters so the Stamp Editor detects the serial
    port to allow programming user code. (B&B Electronics make nice
    little line powered converters Model 232LPTTL for ~$30. But still
    need to add the echo req'd for Stamp Editor.)

    So stop cost bashing the Basic Stamps!
