    Hello,
    I'm a VB developer interested in designing my own programmable ICs.
    What equipement will I need and where is the best place to start
    looking?

    Thanks............Bassman
     
  2. IC design? What exactly do you have in mind?
    You will need a programmer to flash the chips (if you choose PICs). You
    will also need some PICs. Outside of that, you will need the typical stuff
    you need to tinker in electronics (parts, DMM, proto boards, etc). I use
    the melabs usb programmer from www.melabs.com They also have development
    boards available. www.microchip.com is the place to get info about PICs in
    general (datasheets, development tools, sample parts).

    Isn't it interesting what non-embedded people think we do ??

    You are not allowed to run VB on virtual machines. Programmable ICs
    are virtual machines, thus prohibited by MS laws.
     
  5. Hmm... So want want to become a digital chip designer? I doubt your
    experience in VB will be of much value. You will need a good insight in the
    physics of semiconductors and even a better insight in logical design.
    Programmable ICs are are a class in their own right. The equipment you need,
    can be found in the labs of Intel, AMD, Xilinx and Lattice to name just a
    few. I only guess its way beyond your budget. So may I ask: What do you
    really want?

  6. The thought occured to me that you may not want to design programmable ICs
    but want to design something using programmable ICs. As you use PIC as an
    example I will stick with it. First thing I advise, read:
    http://www.voti.nl/swp/n_index.html
    which IMHO is a good intro.
    When you're through it, you will have some idea already. Besides, you will
    find all the information you need to make a PIC blink a LED. Which is
    considered the "Hello world" of PIC programming. I think you can do with
    this for the moment.(But if you have questions, come again. Someone here
    might know the answers.)

    Thanks for the info, what I'm trying to do is replicate my garage door
    remote.
     
  8. So you'll have to gather information about this particular remote. This
    things can be really complicated these days. Have a look at:
    http://focus.ti.com/lit/ds/slws011d/slws011d.pdf
    for instance.
    Once you know what chip(set) is used in your remote, you may be able to
    decide whether or not you can duplicate it by using the original chip(s).

    Microchip sells some PICs with build in RF but of course I don't know if
    they cover the frequency range you need and/or if they're powerfull enough
    to emulate the chip in your remote. On the other hand, Microchip has it's
    own chips that can be used for remote openers, maybe even in your one.
    You'll have to dig pretty deep into the bits before you can start some
    design. Programming is only the last step.
