Configuration error

[Russ Kincaid]

My simple program compiles OK but when I try to program, I get "configuration error". I don't understand how the configuration can be in error, it is what it is, isn't it? This is my program:
code
rem device 12F675
CMCON = 7 'SETS DIGITAL MODE
TRISIO = %00111100 'MAKES GPIO.2,3,4,AND 5 AN INPUT
DEFINE OSCCAL_1K 1 'PRESERVES OSCILLATOR CALIBRATION
J VAR BYTE 'DEFINE VARIABLE J
low GPIO.0

END

If I try to erase the micro, I get "configuration error". I am using MicroCode Studio. I found Melanie's post on configuration fuses but I don't know enough to understand.

What version of PBP are you using? PM or MPASM(version?).

Have you done anything to the 12F675.inc file in the PBP directory?

[Russ Kincaid]

I am using melabs programmer version 4.01, microcode studio version 2.3.0.0 and compiler version is picbasic pro 2.46. I don't know if that answers your question. I have not looked at the include file (or know where to find it).

[HenrikOlsson]

Did you select the correct device in the dropdown list in MicroCodeStudio? Most programing softwares autoselect the device based on the device that the loaded .hex file was compiled for. (I don't know about the one you're using though). So, if you select the wrong device in MCS you'll get the wrong device in the programing software.

Works for me
but like HenrikOlsson said make sure you have 12f675 selected
16f628 is the default on mine

I did a read on the 12F675 and it came up "code protected". How did that happen? I thought default was not protected. How could I read the memory if it was protected? I suppose I will have to throw away the two that I tried to program. I hesitate to try a 3rd 12F675 but they are cheap, thank the Lord.

Look at the program that your programmer uses. Some have a way to set the fuses there. If you have one like that find out how to disable that option. It is nothing but trouble.

Dave,

Unsure that this matters, but I had a heck-of-a fun time with an 833 chip last week, due in no small part to the programmer. Current numbers are:
Programmer 4.31
MCS 3.0.0.5
PBPro 2.50c

Microcode studio is an easy fix. The programmer should probably be upgraded, and unless somebody more literate than I takes issue, I'll say that you're ok with PBPro.

There is a "configuration" window that shows up under the "view" menu in the programmer. I've never had an issue with it, it will over-write any settings you put in the code. Is it the best way? Who the heck knows. It can make your life miserable if you are trying to do something specific and not pay attention to it.....

Hope that helps

OK, I tried a 3rd 12F675 and altho I made sure the configuration was xt_osc and not code protected, the program failed with configuration error and when I read the memory, it comes up lp osc and code protected. I don't know what to do except uninstall and re-install the program.

Hi Russ,
I use the PICKit2 and sometimes encounter that same scenario. The PICKit2 doesn't have an erase button (working from memory here as I am not home) so they say to select the chip you are using and program blank without selecting a hex file, to erase. This usually fixes the PIC and it programs when I load the hex. Crazy though it seems, when I get one like that my old JDM Clone won't erase it either.

What programmer are you using?

The PICKit2 doesn't have an erase button

Mine does

Russ,

Take it to the step where you actually program the chip, press "view" and open the "configuration" window, and post what the settings are, here, would you? I'm interested in what it's telling you.....
By default, they should match -exactly- the listing in the 12f675.inc file in c:\pbp (or wherever it lives)
If you've changed them in the config window and saved it, then the saved values will be the default.

By way of example, you should have an option for setting the osc. The default may be XT, but you can change it to INTOSC and save the settings. Quite handy (I can see Dave cringing right now - sorry) handy if you never plan to use any other compiler...... not so handy if the code needs to be portable.

I am having quite a time with some code that makes Thomas the Tank Engine look complex. Oddly enough it's a 12f675. AND, the routines are simple and have been used a few times, not precisely the same, but the methodology. Now it won't run. I loaded a working file into the same chip on the same development board and it won't run either. The working file was built last week, and the MeProg software upgraded shortly thereafter.

Any time I try to program a 12F675, the default configuration is LP osc and code protected.


If I change the configuration to EXTOSC and NOT PROTECTED and try to program, I get a configuration error.


Now, when I read the part, the configuration changes to LP osc and code protected.

I am using the Melabs programmer. I can make a jpg image of the configuration window but don't know how to post it.
