Hello,

I'm seeking for an "update", or smth else, for "spep.exe" application (a dos application). This software allow us to program PIC16f84 with the device PIC 16CXX-PGM from Parallax. It is possible to use my programmer with Windows ?

Thanks for your answer

    I think you may be looking back to the early days of Parallax.
    Can somebody acknowledge that this company indeed made a PIC programer?
    If you actually· have one, you might try customer support.

    Aside from that, I would have to say that Parallax moved on from PIC products after it created a tokenized Basic language with a boot loader, and doesn't real support programing PICs through direct downloading of HEX files and so forth.
    It is an interesting bit of history though. Or maybe there was another company using the name of Parallax.

    So, you may need to try the PIC support group at Yahoo.
    There are very many PIC16F84 programers available from very cheap DIY to expensive. I am sure you can locate one that will do nicely.

    Oh man, that's reeeeeeally old. Parallax got out of that business a number of years back. The last update I got from Rocklin for mine was aroudn 1997. THey sold the line to Tech-Tools sometime around 1999 IIRC. TT has an update kit for the programmers to use their newer software:

    This is not a sig. This is a duck. Quack.

    Since were on the topic of PICs, I have a similar question.

    I bought a kit that displays the time and date on a roll around 5x7 LED matrix. It uses I believe a PIC16f54 or 84 (I'm not sure of the exact number but that's not too important right now).

    I want to know if it is possible to download the code and view it. My guess is probably not as it has been assembled.

    I would like to learn from it to do something similar on an SX28.

    Comments...sugestions.

    Thanks,

    I believe that you can easily find the code at an online web site.

    Search Google for the Propeler Clock.
    You could possible program an SX-18 to do the same task if it is a PIC16f84. There is only one pin difference [noparse][[/noparse]the PIC has 13 I/O and the SX has 12I/O].

    You will have to build your own SX-18 programmer, but it really isn't that hard if you alread own the SX-Key. It can even be done on a breadboard. Some adjustment for the extra speed must be made and there is an SX mode to mimic the PIC by slowing the instruction pipeline down to 25%. It is a really good exercise in comparison of the two technologies and you begin to recognize exactly why the SX is much faster.

    If you look at the set of PIC mneumonics and compare to the SX mneumonics, all are included in the SX on a one to one function relationship. Some of the names are different though. SX has four additional commands.

    The PIC devices are similar to the SX-Ubicoms in that they allow the person that programs them to make the code locked and relatively unreadable to others. I think the PIC uses a different scheme that the SXs. The SXs give a read out but it is scrambled into nonsense.

    By the way, the Parallax PIC program is still being sold and has downloadable software to compile. I was very surprised.

    If the code protect bit on the PIC processor is set when it was programmed, then you won't be able to read the program from the PIC.

    There are plans and inexpensive kits to program PIC processor. I paid a whopping $11 for a P16PRO40 programmer (kit), which is a basic PIC programmer that works with many of the earlier chips like the P16F84. Google 'DIY PIC Programmer' and you'll find plans to build your own programmer and the programming software is also free here www.ic-prog.com/
