Hi,

I have an issue with PIC18F26K42 when i try to compile the code.

Error message is:

Launching the compiler...
C:\Program Files (x86)\Flowcode 7\compilers\pic\bin\xc8.exe --chip=18F26K42 "PIMF_amplifier_controller_v6.c" --MSGDISABLE=359,1273,1388
(922) chip "18F26K42" not present in chipinfo file "C:\PROGRA~2\FLOWCO~2\COMPIL~1\pic\dat\picc-18.ini"
(908) exit status = 1
C:\Program Files (x86)\Flowcode 7\compilers\pic\bin\xc8.exe reported error code 1

Indeed inside the picc-18 file, the 18F26K42 chipinfo are missing and both related files from cfgdata and cfgmap folders
are also missing.

Can somebody help me with these files, or from where to take the data to insert them in the existing files.

Thank you

Hello,

It looks like this might be a bug in the version of the XC8 compiler we ship with Flowcode.

To solve the problem it might be worth downloading and installing the latest version of the XC8 compiler from Microchip and then pointing Flowcode at the new compiler by changing the compiler path in the compiler options window.

Let us know how you get on.

Hi Benj,

I tried your suggestion and the result is below:

Thanks for letting us know. This updated definition file should solve the problem.

Simply copy the file to your "Flowcode 7/FCD/PIC" folder and restart Flowcode.
Let us know how you get on.

Hi Benj,

I copied the file.
Without using the interrupt the code is compiled successfully.
With TMR0 interrupt activated error message is:

102: T0CONbits.T0CS = 0;

OK thanks, I'll have a better pass through the file tomorrow for you and check there aren't more problems lurking.

Right the attached file should hopefully solve the issues for you.
Let us know how you get on.

The error code list is shorter but still there.
If i can help in another way, besides compiling and posting error messages, just let me know.
TMR0 was used for interrupt.

Hello,

These devices are significantly different from other devices in the 8-bit PIC family, the SPI and I2C peripherals amongst other things are basically totally unique. For now I would advise to use a different device if at all possible.

If not possible to use a different device then I've made a start at supporting the I2C and SPI peripherals but without a test chip I don't hold much hope of it working as the peripherals are now extremely complex.

Ok Ben,

I understand were the problem is.
I already found a replacement (18f26K80).
Thank you for explanations.
