Code Compatibility Issue

Hello, I am working on a program that checks the continuity of several circuits and processes the data to genarate several output signals. I have the code working flawlessly on my 16F84A but when I run the same code on other PICs such as the 16F88 and 16F767 it does not run properly. The code seems to constantly reset the output signals resulting in a signal that rapidly switches from high to low when it should be steady high or low (this is probably not the only thing that the code is doing wrong). I have disabled the ADC module and the comparators on the PICs that have them and I have no idea what I am doing wrong. I have tried disabling the watchdog timers and changing a few other configuration setting but nothing seems to work. My final application will most likly use a PIC16F57 so just using the F84A is not an option. Does anyone have any ideas about what I might be doing wrong.
Thanks!

PBP, the actual text based source code is relatively transferrable between PICs. However, at the actual binary level, trying to run code for a 16F84a on anything will get you nothing but trouble. You'll probably only have to recompile it for the PIC you want to use. At any rate, you MUST check the datasheets to see the main differences between the 2 types of PICs, the differences in the pins, differences in registers, etc. You can't just go slappin' one PICs code into another type and expect it to work.

I have been recompiling the code for the PIC I want to use all along and it still does not work. My hardware is built so that all the corsponding I/O pins on ports A and B are conected to the same things on each PIC. In my own experience I have been able to use the PIC16F767 normaly by disabling the ADC and the comparator but this time that doesnt seem to be enough. Any other ideas?

Show some code...

what compiller

hi its andrew i just compilled your program using micro code studio (pic basci pro compiller ) and it compiles fine microcode studio is a free download
i don't know what compiller editor software you are using but you could try these 2 programs

Hi Andrew,
Just a Wild Arse Guess on my part, but the config registers look much more complicated on that particular chip than the 16f84, which is simple. See 15.1 of the data sheet for more confusion. :)

Is anyone supposed to be able to actually read that?

Everyone's got a "Colon", and they all stink. :eek:

It's exactly the same code, except for the changes/fixes...you know it, I know it, the guy that wrote it knows it and should be able to read his own stuff....and you don't have to scroll thru 17 pages of stuff to get to the end...

Ha, It's exactly the same. Except EVERYTHING'S different.

You've changed the SYMBOL's to VAR's, removed the LET's and changed a binary number to decimal. And while the program now looks completely different. After compiling, the HEX file will be byte for byte identical to the original code. No changes. No fixes.

Since it doesn't look anything like the original program, the "guy that wrote it" now has to spend probably several hours searching colon by colon, trying to find what it was that you changed. (took me an hour)

And won't he be pissed after doing all that, only to find out that it doesn't make any difference. Because it's exactly the same program, just written with different words, and a really bad format.

There's no way to follow the flow of the program. You can't see any type of structure. It's just a bunch of lines of code. Very long lines at that. My guess is that you have a Wide screen monitor and make the code fit a maximized window, all the way across the screen. For anyone with a normal sized screen, they're now scrolling left and right, instead of up and down. And when viewing in a browser, it all wraps around and you can't find where one line ends and the next one begins.

And one last problem ... There's no room for comments.
Come back to that program in 6 months, and you're going to need some laxitives for those Colon's.

On a scale of 1-10, I'd give this formatting a 9 for the the best way to NOT write your program.

The manual says 'Symbol can only be used to alias a variable, not to create it'. As far as the LET and SYMBOL, I referenced both of those at the beginning of the post... No changes, no fixes? I'm wondering...

Huh...I'm fairly handy with an 'Enter' key, and maybe a little bit of the 'Delete' key. Only took me about a couple of minutes or so to get one command per line. And again, the guy should be able to recognize what's where in the first place.

Maybe so, but maybe he'll learn a bit of something here and there and fix his own problem.

Could be... I run 16 x 12, turned 90 degrees. And who's to say what's normal? What does your newspaper, comic book, any other book look like? I'll bet if you put a page from one of those across your screen, it would fit a lot better if the screen was rotated about 90 degree, left or right... If anything, I'd say the way 'normal' people use a monitor is 'abnormal' compared to the way people have been reading printed material for years.

True...but I won't be coming back to it.

I think what you really mean is that you'd give this formatting a 9 for the best way NOT to write YOUR program.
However, I'd give this formatting a 10 for the BEST way to write MY program.

No comment....

I use “find and replace” to “de-colon-ize” the code and flip it from a big horizontal file to a big vertical file.

Two problems, have to watch for wanted colons like labels, and the vertical code still has no comments. :)

All the labels have a space after the colon. The colons in the middle of the code (except for here with the vB smilies and such) always have characters on both sides. And Cntrl-H (Word) and Cntrl-R (MCS) are my friend.

The manual says 'Symbol can only be used to alias a variable, not to create it'.

The only uses of SYMBOL in the original program was as an ALIAS. So nothing disagrees with the manual.

And LET is shown in the manual as a valid statement. (although optional)

So to read your re-formatted program, we have to re-format it again???

But it doesn't really agree either. doesn't say anything about being able to use one of the 'predefined' variables, such as PortA...

Hey, at least I'm not wasting time posting spam for cheap phones, laptops and camera's! :D

Let's see if i remove my usual 'code template' from and try to format the code a little bit... i've never read/check it carefully if it make sense so far... at least, no compilation error.

Code:

now comments, code section, steps should fit

I fixed the problem. As it turned out there was no problem with my origonal code. The problem lay in the configuration of pin B0. I traced the bad signals I was getting back to that point with my oscilloscope and when I switched the functions of B0 over to C7 it worked as expected. Also, there is absolutly nothing wrong with using the SYMBOL command the way I used it in my origonal code. It simply throws in an alias name for a pin, constant or whatever and makes the program easier to work with. I also prefer to include the LET command as it gives the code a more finished look and in my opinion makes it easier to read.

Great...now I've got to figure out which manual is the latest version.
I know I used to have 2 or 3 PBP manuals laying around, I'm down to one now, Copyright 2004 inside the front cover. Not sure if that's the latest version or not...

Well actually, that one was from a 2002 manual. (I think I'll throw that one away)
I have another one (2005) that has 5.40 as {LET}

But since you can't really know which version someone might have.
It might be a good idea to include the Title of the section along with the number.

Just a thought.
