Hi Everyone,
I'm beta testing Geoff's new Micromite MKII and wanted to try out CFunctions but I'm having problems with the CFuncGen that G8JFC has written. The instructions are excellent and clear, but for some reason I cannot get it to work.
I'm OK with creating the sample project in the MPLab X IDE and can get an elf file that looks about the same size as the example.
When I try to use CFuncGen to create the disassembly I can open the elf file, but no functions or code appear.
So far I have tried:
1) A shorter path name for the directory
2) Updating the version of MPLab X (I'm on v 2.25)
3) Updating the compiler to version 1.33, was on 1.31
4) Recreating the project
I'm running Windows 7.
I do get warning messages from Symantec when I try to install CFuncGen, but according to the log it allows the installer to run.
Wondering if anyone else is having this problem or knows what is going wrong.

As this is my first original post, just want to say I've enjoyed reading the forum since the Maximite first came out. This is the first time that I've hit a problem that someone else has not already encountered before me. The Micromite, is so far the most useful incarnation of the Maximite series. It is so cheap and easy to use, I almost went through my tube of PIC150's the first week I got them.

Hi Jimbotron

Sounds like your environment variables may not be set correctly.

Open up a Console (cmd.exe) and take a look at the PATH variable - echo %PATH%. Since U have MPLabX and XC32 installed you should have an entry in PATH such as

C:\Program Files (x86)\Microchip\xc32\v1.31\bin

If NOT, then that is the problem, and you will need to re-install XC32. CFuncGen uses components from XC32 - so if the XC32 bin directory is not in the path, then CFuncGen will not properly execute - I should probably put in more checks and user notifications if CFuncGen cannot find all the XC32 bits needed :)

Also look into the folder where the .ELF file has been generated by XC32, and after running CFuncGen you should find a file with a .DIS extension - again if not, then you probably have the problem with the PATH environment variable.

Please let me know how it goes

Peter

Thanks Peter,
That was it. I manually added the compiler directory to my user path and it worked straight away.
I also reran the installer and noticed that there is an option to add X32 to the path and it was unchecked. Can't remember if it was this way the first time I ran it.

BTW, I was getting the dis file but it was empty.

Thanks Jim

Great news.

Hope to hear of your CFunction(s) adventures soon
