PICKINI V4 - an easy to build, self adjusting PI detector

[geoscash1]

I can tell you how to do it with mikroC which I think is easier than mplab. And I think you have to add a compiler to mplab to get it to work. MikroC already has the compiler. What you want to do is install the mikroC program and copy F117's source code written in C from his website (not his hex file) into a new project. Then, at the top of the page, click on "Project" and then "Edit Project" There, you will see the settings for the oscillator, MCLR, etc. that I talked about above. Modify the settings in accordance with post 84, and then build the project by clicking on the "Build" tab and then "Build" again. What you have then done is generate hex code that has the correct project settings. Make a note of the file where the hex code mikroC generated is stored.

Then download the PICkit 3 software -- here is a link http://en.freedownloadmanager.org/Wi...Ckit-FREE.html -- install it, hook up your programmer with the PIC installed and open the PICkit 3 software up. It should pick up your PIC. I actually use the PICkit 2 version, but I think they are about the same. Import the hex code from the project file that was created by mikroC.

I think that PICkit 3 already has the correct file for the PIC 16F1824 but if not, you can follow the basic procedure I wrote up in post 215. You just need to find the PIC 16F1824 in the list (also see post 215 above for how to find it).

First erase your PIC and then install the hex code and you should be ready to go.

The good news is that you are very close to getting it to work--you just need to get the right program on the PIC. Pin 4 of this PIC is the MCLR pin. However, it can also be used as an I/O pin if you disable MCLR. That is how F117 is using it. So, when you push the "pin-pointer" switch with MCLR enabled, you are simply resetting the PIC. In addition, your PIC probably has the wrong oscillator setting which means it is running too slow. All of this is fixed in the project settings.

If all else fails, pm me your address and I'll mail you a PIC with the correct program installed. Then, when you get a chance, you can mail me a blank PIC back and we will be even on our inventory.

Let me know if you get stuck.

Edit: To copy F117's source code in C, open his file up (http://users.telenet.be/willaert/MD/.../v4/Pickini4.c) with wordpad (or another program like it) and then copy all of the code and then paste it in a new project in mikroC.

Excellent, thank you for the very informative reply Dan, it is much appreciated. With those instructions it should be easy to get it finished up. I do already have mikroC pro so done deal.

But,

I found what the problem is or was, my pickit 3 programmer just flat died. it was loading code then just stopped. I checked the power on board after snapping the red case apart and it really just up and died, never ever had one just die like that before....lol

So now I need to buy a new one or another programmer, probably hit ebay here in awhile, glad there relatively cheap, only problem is the wait... I do have other programmers but they don't support the chip were using and one of them (my velleman experimenter/programmer) would work but I need a pc with an available 9 pin plug to be able to use it.

Thanks for the offer for the chip, are you here in the states?

Yes, I'm in northern California.

Great that you found the problem.

BTW, disregard my statement in my above post "Import the hex code from the project file that was created by mikroC."

Instead, import Bernard's C code into the new project in mikroC. I ran out of time to edit my original post and forgot to delete that line.

I use the "enhanced PICkit 2" which is an older version and is still available on Ebay, but it would probably be better to get a PICkit 3 programmer.


Best,

Dan

Heloo dan, i try to compile with the source code from F1117, but its stuck on some parameter that i dont know when i try to build hex, im not a programer.

Hi ripsdevala,

I didn't have any problem compiling his C code in mikroC. You might check to see that you aren't trying to compile Bernard's hex code which is just lines of numbers. Besides that, check to see that you copied all of his C code. I used [ctrl a] then right-click copy (which I know you already know).

Ripsdevala,

I forgot that when you open a new project, mikroC already has void main() { } so before you paste Bernard's C code, delete that existing little bit of code. Bernard's code already has it and it would not allow it to compile if it was included again. That may have been why you couldn't get it to compile.

Yes...that what i mean (void), idk what is that, let me try that later, many thanks

Hi,
I've just received my pickit 3 with adapter board.
I've installed MPLAB IDE v3.50, MP X LAB IPE v3.50 and PICKIT 3 v3.01.
I did not try yet mikroC but i'm not sure my unit is working properly :
When i lauch pickit3 and search for device, i get a message : "Unsupported part (ID=2740)"
and in the DEVICE FAMILY menu, the PIC16F does not exist.
The adapter board is set up as writen on (DIP14 : J1=B, J2=2-3, J3=2-3).
I can't find anything about this on the NET but maybe i'm searching with the wrong keywords.
Thanks for help

I'll try to help.

When you start the Pickit 3 software, you need to have already had the PIC in it's socket. The software then automatically picks it up.

If you did have the PIC already installed and the software is not picking it up, you may be missing the configuration file for the 16F1824. See post 215 above about how to install it. Although I wrote it up about the Pickit 2 programmer, I think the Pickit 3 works about the same. Just rename the file to the appropriate name for the Pickit3 and copy it to the applicable directory. You may need a different file than the one I used. Google it for the Pickit3 if that is the case.

To find the PIC from the dropdown list, also see post 215 above. It think it's also about the same as the Pickit 2.

Hope that helps.

Edited to state that the configuration file may be different for the Pickit3 than the one mentioned in post 215 above.

[ripsdevala]

Your configuration is same with my clone pickit, try another chip, maybe you have defect one

[F117]

Check the power supply from PICKit 3 - 5VDC to the microcontroller.

[reptooyep]

Hi, thanks for help.
I'll check for config file installation.
I measure 0v between VDD and VSS on the adapter board but i've checked the connections between pins of the chip and output of PICKIT3; everything is fine.
I've also tryed with a new chip.
I've also tryed with MPLAB mode and load the hex file from the IDE but i get a pickit error.
Strange ..

[F117]

You have to enable power from the PICKit3 adapter ( from MPLAB: programmer->settings-> power-> power target circuit from PICKit3) to the device.




Hope this helps,

Update firmware?
Wrong zip slot pin?
Compability program to xp sp2 for standalone software?

[reptooyep]

OK,
Thanks,
my issue was simple. As F117 says, this was a power ON issue .... So simple !!!
I'm not so bad at AVR programming but this is my first PIC test.
Last thing to do for me is to modify the source code in order to make it work with a phone vibrator to make an underwater detector.
I'll publish soon my SMD version with the new source after i'm sure it works. (The board is already etched).
The source from mikroC does not compile in MPLAB, is it normal ?
Last question :
Does MPLAB needs to be installed to make PICKIT working ?
Thanks a lot

[ripsdevala]

Nice, make it work with led signal repto, and make it anti emi to , cant use it near human machine activity, otherwise its perfect.

[reptooyep]

I thought it did not work properly cause when i switch between mplab mode and pickit mode, i must reload the pickot bootloader.
Finaly, it seems to be the normal functionning.
My detector will work underwater, so, i'm not afraid of EMI and human activity.
