Starting Parallax!

Hey there,

Just checked those "Read First" guides, they are good!

So, I love to learn some Parallax SX and also the Propeller series.

Apart from the SX USB key programmer, should I have a 5V regulated supply to the circuit? I'm constructing my own circuit with those microcontroller.

And how different would it be when I program these in ASM, since I have working knowledge on PIC 16/18F ASM and some 68HC11 ASM too.

Thanks. smile.gif

    If you can program the cranky PICs in asm then programming the propeller will be easy!

    PIC asm is so old school....non-linear program memory and all that.

    The SX is EOL'ed (End Of Life) because Ubicom, the waffer supplier, discontenued them. Parallax will only have about 3 years worth before they are gone for good, so I suggest starting the Propeller. The Propeller can write in SPIN and ASM so the hard part of it (the ASM) is already known, it will be easy.

    Computers are microcontrolled.

    Robots are microcontrolled.
    I am microcontrolled.

    But you·can·call me micro.

    If it's not Parallax then don't even bother.

    I have changed my avatar so that I will no longer be confused with others who use generic avatars (and I'm more of a Prop head then a BS2 nut, anyway)

    The 16-bit PICs have a very nice architecture, and deliver up to 40 MIPS (60 MIPS will be available soon).

    Leon, that sounds much better than the 8bit PICs I learned to program.
    They were weird to code for and at 4cycles per instruction and a low clock rate were pretty slow.

    Microchip has some nice stuff...like that cheap ethernet chip.... I saw it paired
    with a propeller in a design over on ladyada's website... ladyada is a really geeky girl smile.gif

    I have piles of PIC stuff, boards, books, you name it...all pretty much useless to me now.


    If they want to make the Propeller2 a very interesting chip putting ethernet hardware on the chip
    would sure do it.

    I use PICs a lot, including the PIC16 and PIC18, and don't have any problems with them. They are cheap and support is excellent.

    The XMOS chips can do 100 Mbps Ethernet in software with an external Phy chip, it might be feasible on the Propeller II.
