    FWIW, I bought the PIckit2 ...& think it's the best thing since the proverbial sliced (it even has a function that replicates the h/w normally needed to get your PIC interfaced with your PC serial comms wise ....normally you'd need to buy a signal level converter like a MAX232, but such capability is integral to the Pickit2 ...check out Uart Tool once you buy it & install the software).

    Re languages, I started off thinking I'd learn assembly but alas, I spontaneously combusted when I tried to get something as simple as gettting an LED to light up!

    PIC basic is much more digestible... I've got my PICs doing all sorts of stuff now ...eg just finished a program that carries out AtoD, then ultimately controls an AGC circuit based on the AtoD'ed incoming level etc ...I'd have had a beard like ZZ top trying to figure that lot out in Assembly!

    two Z axis ???:heehee:

    John S -

  3. I use a programmer that came, well the PCB did, with the Myke Predko's book Programming and Customizing the PIC Microcontroller. Can't recommend the book but it was cheap (well mine was) and with a downloaded copy of MPLAB and the C18 compiler I've been programming away in C happily. I've always thought C a better language to program hardware in than Basic (discuss*) but each to their own.

    Unless you are happy as a pig in sh*t with a soldering iron and a scope (which, sadly, I am) I'd buy the PicKit or one of the other proprietary tools.

    :)


    *The main advantage for me - non-CNC related - is that there are a lot of C libraries out there for CANBus, TCP/IP stacks and on the latest PICs USB interfacing, all of which I have used - none of which are easy program in Basic. For the un-initiated CANBus is the network that talks to the engine management system on most modern cars... I did some projects linking that to a laptop via a wireless connection to monitor and adjust engine management parameters in real-time.

  4. Thanks for eveyones input so far.

    I have just had a quick google looking for the UCN8504B driver chips, could not find any UK suppliers, I did find a guy one eBay selling them, but wants £7.65 Each plus £3.75 for postage, so a min of £26.70 for 3 IC's.

    Also wile I was on eBay I had a quick look at the prebuilt driver boards, most where from China/Hong Kong and only supports voltages upto 24volts.

    I know going down the PIC route will cost more then a prebuilt driver, but at least once I have got the programmer I can use it for any other projects I might have.

    It looks like the site's spam filter isn't working that well!

    I'll hazard a guess you meant UCN5804B ...they are available in the UK. Here's where I bought mine from


    http://www.cricklewoodelectronics.co...0&cat=0&page=1 (it's a great little chip)

    It's only saved you a couple of quid, but at least they're UK based (& a good company at that)

    fixed the spam...

    Ah, another devotee of Cricklewood Electronics...

    CLaNZeR has designed and built some great PIC programmers and software, hopefully he will add to this thread

    The best PICs to use are the 18F series as they are the most powerful, processors, with up to about 4K ram.
    I would say the PIC18f4620 is the best processor to start with.
    Thanks
    Darren
