Jim,

I'm facing the same problem. I tried to create my own routines, but I
got stuck in the same place. I can't communicate.

If you get any help, please, let me know.

Thanks

Dinho

   All

   I am trying to get the MSSP module in a PIC16F877 to work in I2C
mode.
   To do this, I have downloaded AN734 from the Microchip website, and
   tried assembling it per the instructions on the ap note.   But
whenever
   I do this, I get 29+ errors stating that "Illegal opcode (NAME) in
   16F877.lkr file.   So, then I decided to try it in it's original form
   (Using part# 16F872). [ I modified the original file by swapping my
877
   part for the original 872].  When I do this, I get the same error,
only
   there is only 23 of them.   The 29 errors I saw were when I switched
   from the 872 in the ap note to the 877 that I want to use.

   So, my questions are......

   1).   Does anyone know why don't the original assemble correctly?

   2).   Does anyone know why changing from an 872 to an 877 doesn't
work?

   3).   Does anyone know how can I get it to work with the 877?


    Please advise ASAP.    I am nearing the point in the project where
this
    processor and application is becomming necessary, and I'm running
out
    of time trying to get this part of the project working.   I thought
    this would be the easy part to get going, but it's not turning out
that
    way.

    I'll be anxiously awaiting a response.

                                            Thanks and Regards,


                                                   Jim
