I don't remember if I had to do a update to get more chips recognized by the programmer. If I did, I have no idea where I got the update to down load. Like I said I have all the renard start address hex files. I don't need a program to compile with to make a hex file.
    I am a bit confused. The only time you need to modify the start address is if you are using a shared media network like xbee. If you have xbee then you have had to already do a significant level of planning. If you are using a USB dongle, a pixel stic, or a bridge, you should not need to change the start address.


    2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show.

    I wasn't trying to modify a start address. I was trying to program a 16f688 with a start address. But my problem was, the PicKit2 programmer was not allowing me to pick the 16f688 from a selection of devices. So I uninstalled the programmer and went and found one on the Web and down loaded it. From there I had no more problem selecting the 16f688 from the list in the programmer.
    all is good with that now.

    I have other problems with my Xbees failure to communicate with X-CTU. I found another release that works.
    I also found some of the programs we used in XP and windows 7 don't work well in windows 10.

    ok, bringing this thread back up.
    Now that I have time to mess with MPLABS I would like to make a HEX file from a .asm file.

    Here is what I have, I bring the .asm file into MPLABS.
    I can leave it as is or modify it for how I want it to work.
    After I make the changes, what do I do next?
    Can't seem to find what I need to know from the Help tab to assemble and make the HEX file.

    back in november (post#5) i lied when i said i had done this before with mplab x. i finally found this tutorial at pololu and was able to make a hex file from the renard assembler code. i still needed to use the software that came with the pic2 to get the hex file on my pics

    Ok got MPLABS X installed. Lost already. the screen in the tutorial is no where like what I see when I start the program. Maybe I did or did not do something when installing it. There is no tab with "New Project" to select from.
    Ok, scratch that note above. The program I should have been opening was hidden in a picture on the decktop. urgh!

    So shouldn't I be opening a Renard associated.asm file to compile instead of following what the tutorial is instructing?

    If you dig through the program folder of MPLAB you will find one called MPASMWIN, inside it should be a exe file. send a shortcut to the desktop for it. Use that to make your .hex file from the .asm file.
    This simply bypasses the main program so you do not need to create a 'project'

    This should be the same file path or lat least close, so you know where to look......
