| Help compiling for a 16f628A |

I recently wrote a small piece of code for the pic16f628 but accidently ordered 628A's. I have an old version of the compiler that does not work for the A's. Can someone please do me a favor and compile this code for me? Thanks,
Ringo

Be aware that this line may not produce the desired result,
based on the compiler version.
This is because FALSE is defined as 0, but in a modern
version of the compiler, FALSE is not a valid argument
for the setup_comparator() function. You have to use
NC_NC_NC_NC as an argument. For PCM vs. 3.188
it's defined like this:
#define NC_NC_NC_NC 0x0ff07
But in a slightly earlier version, it had a different
definition, as I recall.
---------------------------
What is your version of the compiler ?
There may be a better way for you to use it for the 16F628A.
If I know your compiler version, I can check on it. |

I have 3.050. The setup_comparator(FALSE); line was inserted by the pic wizard, so I hope it works. Would you mind taking it out and compiling it for me and sending it to me via email?
Thanks
Ringo

There's no point in having people compile the code for you, because
you'll need to revise it as you discover bugs.
For example, are you using Low Voltage programming mode ?
If not, you need to put NOLVP at the end of your #fuses statement.
I used PCM vs. 3.188 and compiled your file for both the 16F628
and the 16F628A. I then compared the two hex files. The only
difference is the name of the PIC that CCS puts on the end of the file.
(I changed the setup_comparators() line to use NC_NC_NC_NC as
the parameter before compiling).
So the modern compiler (vs. 3.188) doesn't treat the two PICs
differently. The hex file code is the same for both.
So if your version of the compiler works for the 16F628, it should
mostly work for the "A" version. If you look in the back of the
data sheet for the 16F628A, it has "APPENDIX C: DEVICE MIGRATIONS".
This section tells the differences between the "A" and the "non-A"
versions of the PIC. Most of the changes have to do with the Config bits
(#fuses) for Code Protect, or various oscillator modes. But you're not
using those modes. So I don't think it's a problem. |

Thanks for the info on the compiled versions, that’s what I needed to know. I'll just compile it for the 628 and then edit it and add the A just for completeness. As for revising the code I think it is done. It's a very simple project that just needs to send a serial string to a piece of equipment on bootup, then switch in a relay to let the pc take over. It works and I just wanted to use up the 628A's that I got stuck with.
Thanks For the help.
Ringo
