    Alberto I wanna contribute to improve your programmer supported devices but I have a question, when you mean "parallel memory" is flash memory?

     
  • Alberto Maccioni

    Either Flash or EEPROM, but with parallel interface.
    Since most devices have more than 11 IO pins a new expansion board is required.

     
    • Vitor_Boss

      Vitor_Boss - 2012-12-31

      You can use the 74F574 to multiply the output IO. And I know an expansion board is required, so we can think together to do it.

    For EEPROM memories there is a specific package like DIL or PLCC? I have a lot of EEPROM memories here, I only need know your plans to implement those.

     
  • Alberto Maccioni

    I currently have no time to develop anything; DIL devices are disappearing, and other packages are mostly soldered, so I really don't know if there is still need for such an adapter.
    If you need one you should see what devices and what packages you use.

    I have a lot of different packages here and time to develop all needed implementations, I'm thinking to do a board with DIL40 and small adapters to other packages. What you think?

     
  • Alberto Maccioni

    Sure, go ahead.
    You may consider to put more than one package on the same adapter.

    I've found a programmer on web and is exactly what I was thinking:http://www.batronix.com/pdf/USBChipProgrammerDeviceList.pdf

     
  • Alberto Maccioni

    Ok, then you can borrow the overall concept regarding sockets.

    Alberto the ports RA3, RA4 and RA5 are used for something on latest firmware?

     
  • Alberto Maccioni

    They are general IO channels, can be used.

      I would agree that parallel EPROMs are going away, but are not gone. Some hobbyists repair and use older test equipment or fool around with old personal computers. I am on some forums for HP and Tek test equipment where reading ROMs and writing EPROM replacements happen from time to time as the old ROMs become flaky.
      As a place to start, reading some of the popular ROM chips, MK36000 series or MC68766 that hardly anyone can find a reader for these days and being able to dump the contents into common 32K or 64K EPROMs would be very useful. Yes, adapters (or hand rewiring) are needed to replace these ROMs but a useful piece of test equipment can be brought back to life.

    Sorry, just learning how to post correctly.

  • Alberto Maccioni

    Ok, then you can read all datasheets and compare the pinouts; you should come with a minimum set of sockets required to read or write all of them.

    is it possible to include oscilloscope and logic analyzer feature in this project?

     
  • Alberto Maccioni

    Please explain what you mean.

     
    • Raymond

      Raymond - 2014-04-08

      i mean just add 1 channel oscilloscope or use the extra expansion port/pin, in simple idea just read adc value then send it to pc(like this project https://code.google.com/p/xoscillo/ xoscillo). Save the data and view it later. Same as the logic analyzer.

       
      • Alberto Maccioni

        This is an HID device, so the maximum packet rate is 1 every ms; not really useful for an oscilloscope or logic analyzer.

          yes alberto, i want to ask that for school demo purpose only. tnx.

           
          • Alberto Maccioni

            you can do it yourself using the -command option with op or opgui.
            The instructions READ_B and READ_AC read all the IO ports available.
            With WRITE_RAM and READ_RAM you can set-up the registers of the 18F2550 in order to use the ADC converter on various channels.

    hi I am new in this site. And I start programm micros like HOBBY.
    I have an K150 programmer but I start to make your OpenProgrammer because I want to use 12F1501 and 16F1503 micros and they can't be programmed with K150.
    I have finished the PCB , I have a new PIC18F2550 , but whwn I try to LOAD the hexa OProg_V0.9.0.hex the program of K150 ( named MicroBrn ) do not recognase the Hexa file :
    Said eror fuse....Etc and can not load the file to write in PIC18F2550 .
    May be there are many tipe of Hexa ???? I do not have any ideas to program the main micro.
    If you can help me , please send any good ideas. (sorry for my English)

    Thanks Stefan

     
    • Alberto Maccioni

      The hex file is generated by the MCC18 compiler, so it's correct by definition.
      Exactly what is the error message?

       
  • stefan martin

    stefan martin - 2014-04-17

    Hi, thanks for the quick reply. The error that i got is about FUSE on line 1077
    :0100000022DD

    you have a print screen atached with the error message
    please let me know what i need to do

    thanks

     
    • Alberto Maccioni

      It could be that the tool does not accept config words specified one by one as in the MCC18 generated file.
      Try to open the file with openprog or opgui and save it.
      The newly generated file will have all configs together.

      You have a fuls Hex file
      you should regenerate it with a tru methode
