PICKit2 - warning about configuration words

[flotulopex]

Hello,

I'm using a 16F88 PIC and every time I program it with my PICKit2, I get this warning:
<img src="http://www.picbasic.co.uk/forum/attachment.php?attachmentid=2744&stc=1&d=121630516 0">
The programming will succeed anyway.

My prog starts like this:
<img src="http://www.picbasic.co.uk/forum/attachment.php?attachmentid=2746&stc=1&d=121630540 0">

Something missing/wrong?

Hi, Roger

Generally, you don't care about some fuses cause general use of Pic do not involve their use.

Each have a DEFAULT setting ( ON or OFF ... type of osc ....)

Here Pickit just warns you, coz' you didn't care with some ... that's all.

MPLAB show you the full window ... just look at those you didnt set or clear.

OR Open the MPLAB 16F88.inc file ( Not the PbP one !!! ) ... you'll find everything there !!!

Hi Roger,
Just off the top of my head, doesn't microchip software use MPASM assembler? If so then you need MPASM formatted config statement, or possibly I am all wet

Yes, but the output of that assembler (be it PM or MPASM) that the PICKIT2 cares about is the .HEX file, which, for all practical purposes, should be identical to each other.

See, I don't have a PICKIT2, and what he posted wasn't hex, therefore my MISTAKE was logical. Sorry Roger. Here is the configs avail. for 16f88:

No biggie... Most programmer software needs a HEX file to do the actual programming of the PIC itself. I really can't think of any other file type, other than a straight binary file, that a programmer would use.

If you look in the P16F88.INC file in your MPASM directory, you'll find all of the various config options listed near the end of that file.
OR...near the beginning of the M16F88.INC file in your PBP directory if your using the PM assembler rather than MPASM.

[flotulopex]

I tried to use the config settings as visible in post#5 (original MPASM .INC file). MCS will give me syntax errors when using some of those.

I.e., instead of "CCP1_RB0", I will have to use "CCPMX_OFF" (see code post #1 for more).

Then, I compared with the .DEV file found in MPASM too. Looks like this:

Where's the truth?

I couldn't find any MCS file about those CONFIG settings syntax correspondances. Maybe the fish is here.

[Acetronics2]

Hi, Roger

With MPASM used ... you're to use MPASM syntax !
With PM used ... you're to use PM syntax !

That written ...

MPASM .INC files give you ALL the settings available ... in the MPASM syntax, of course !!!

... capito ???

and, first of all CCPMX_OFF doesn't exist ... you've to CHOOSE your output Pin ...

yes ... D.A.T.A.S.H.E.E.T. !!!

Dur, dur ...

Alain

[flotulopex]

MPASM .INC files give you ALL the settings available ... in the MPASM syntax, of course !!! ... capito ???

¡Si Señor! I think I know that. So where can I find the correct syntax for MCS then??? Me parece qué esto es más difícil.

first of all CCPMX_OFF doesn't exist ... you've to CHOOSE your output Pin..

Hereunder, I highlighted the parameters I replaced by the ones I use normally (in comment) and see what happens (error msg) when the program is compiled by MCS.

Ah?

As you can see, some "original" syntax from the MicroChip file won't be accepted in MCS. I understand MCS is not using "as is" all or part of the content of .INC files. Am I really wrong?

[skimask]

It's not so much the correct syntax for MCS, it's more the correct syntax for the compiler/assembler you are using.
If it's MPASM, the config registers are listed in that particular MCUs INC file in the MPASM directory near the end of the file (usually).
If it's PM, their listed in that particular MCUs INC file in the PBP INC directory near the beginning of the file (usually).

[bcd]

OK - first things first.

Are you compiling with MPASM or the PM assembler ? A look at the Compile and Program Options from the View menu in MCS.

Here is an example of a config line from a project that uses MPASM:
@ __CONFIG _CONFIG1H, _IESO_OFF_1H & _FCMEN_OFF_1H & _OSC_INTIO2_1H

I have also founds that the PicKit2 will complain about this if you do not define every single CONFIG register. I normally define what I know I need to set and leave the rest. It burns and runs fine.

there are a series of defaults in the .INC file in the PBP folder for each chip.

For the 16F87 it looks like :
<code>

</code>

It have put *** to hi light the default the compiler will insert. Using PM the program will use the ones you specify in your code rather than the ones in the INC file. Using MPASM you will get warning about over-writing the contents of the CONFIG bits.

When I moved to MPASM I had to spent a bit of time working out what things were called as some of the names changed. Check out the MPASM INC files to workout what things are called.

EDIT: Looking at you original post you are using PM. Just ignore the warnings - its just the PicKit2 being anal about making sure everything is defined.

[flotulopex]

I use PM.

Thanks for this clarification.

PICkit2 is really great and I was just wondering about those warning I don't get with other PICs.

[botsmaker]

I too sometimes have a problem with pickit2 recognizing the 16f88. It will state that the device is unsupported. It always has a problem with the hex file not having a complete configuration. I gave up using the 16F88 with pickit2.

[Darrel Taylor]

The missing CONFIG words are because the 16F88 has two CONFIG words.

When using PM, DEVICE sets CONFIG1 and DEVICE2 sets CONFIG2.

@ DEVICE  HS_OSC, WDT_OFF, PWRT_ON ; etc
@ DEVICE2 FCMEN_OFF, IESO_OFF

I too sometimes have a problem with pickit2 recognizing the 16f88. It will state that the device is unsupported.

Hmmm, that's odd.
No idea for that one.
<br>

[Dave]

botsmaker, and others... Have any of you out there updated the OS for the pickit2? I havent had any problems with it programming 16F88 or any other pic's...

Dave Purola,
N8NTA

[botsmaker]

Just updated application software to 2.61 and updated OS to 2.32. I get the same response. It will recon the device when I connect it, then when I load the hex file I get the warning. "Device Error-hex file not loaded", "Unsupported part". I'm using micro studio and PBP.

[botsmaker]

This is the warning message I get from pickit2

[botsmaker]

I gave up trying to program the 16f88 with the pickit2 application program. Just use the mplab ide and select pickit2 as the programmer. I was able to program the 16f88 just fine with MPLAB. I used the same ic in both cases, so the ic is ok. I don't know what the problem is, but I need to get back to work.

[Archangel]

This is the warning message I get from pickit2

I have gotten that error too, and when it does so it usually sets code protection too!
The fine print in the pickit2 docs say to reselect the chip ( select another pic and then reselect the one you are using) and then write the chip without selecting a hex, then select your hex and write.

[botsmaker]

I went back to using the pickit2 with the 16f88 and now it will program. Still get a "hex file not loaded error", but at the end of programming I get the green box.

The problem is intermittent. I got less failure when running power of the board instead of powering through the pickit2. In other words, it always programmed.

I did manage to build my own 4 digit meter with a 16f88 and PBP using some of the example code at MEL about driving led displays. This meter will display from 0 to 100.0 volts if you use a rail to rail opamp instead of the LT1077 I got in it now. Below are links to drawing and code.

The problem is intermittent. I got less failure when running power of the board instead of powering through the pickit2. In other words, it always programmed.

Back when I was using a PIC Start I had to add a couple of capacitors across VDD-VSS or it would not program some of the 18Fs.

Maybe a similar problem???

[botsmaker]

I added a photo of the meter at my profile album. I designed a pcb to make up the circuit and had Expresspcb make it. The board can be configured into a frequency counter or event counter. Just load a different program for a new function. Its a multipurpose board. You can also bring out the ports through a 16 pin ribbon connector instead of a 4 digit display.

[mackrackit]

Looks like a useful piece of work! I like the dual function idea.

[flotulopex]

DEVICE sets CONFIG1 and DEVICE2 sets CONFIG2.

Darrel,

Where a hell did you find this information? Come on, tell us, you're working for the NSA or ex-KGB people, no?

Anyway, thanks a lot!!!

[Bruce]

Where a hell did you find this information?

It's explained in the PM assembler manual. PM.TXT.

[Darrel Taylor]

Bruce knew where it was...

Come on, tell us, you're working for the NSA or ex-KGB people, no?

I'd tell you, but then I'd have to kill you.
<br>

[flotulopex]

Brrrrr!!!

Some freezing sweat drops fall along my back. Okay then, I better never ever ask this question again

NB: just a shame this info was not in some help file (MCS or PBP); would have been easier to find for me.
