ADC(1) on 18F26K22 doesn't compile

When I try to use ADC(1) my program fails with the following message.
4ch_no_con_mon.c(1378:23): error: unknown identifier 'VCFG0'
4ch_no_con_mon.c(1378:23): error: invalid operand 'VCFG0'
4ch_no_con_mon.c(1378:18): error: failed to generate expression
4ch_no_con_mon.c(1378:18): error: invalid operand '<<'
4ch_no_con_mon.c(1378:12): error: failed to generate expression
4ch_no_con_mon.c success
failure
......
Return code = 1
ADC(0), ADC(2) and ADC(3) compile ok.
Any ideas guys?
Brian Walsh.

Hi Brian,
I tried a simple flowchart using ADC0 to ADC2 and it compiled for me just fine.
Are you using the latest flowcode V4.5.18.74?
If your flowchart is not commercially sensitive, then if you don't mind posting it, I can see if I can get it to compile.

HI Martin,
I have written a simple program reading ADC(0) - ADC(3) and it compiles. So the problem with my original program must lie elsewhere. Thanks for your help.

Hi Brian, the information you have posted e.g 4ch_no_con_mon.c(1378:23): error: unknown identifier 'VCFG0'
The number within brackets is the line of C code that’s causing the issue.
If you would like to track down the culprit, have a read of this:
http://www.matrixmultimedia.com/mmforum ... =26&t=6936
scroll down to:
C) General use of Flowcode.
If you need help in tracking down the cause of error then just ask (you will need to either upload flwowchart, or send in a pm if private.
As a guess there is a component has not been assigned with correct data or just left blank?

I did a search for "VCFG0" in the component C code and it seems to be used in the ADC component when an external VREF is selected. Further inspection shows that the k22 family does not define the VCFG0 - instead NVCFG0, NVCFG1, PVCFG0 and PVCFG1 are defined.
This affects the PIC_ADC_19.c and PIC_ADC_29.c files. I'll try to get a fix up later today.

I still have the error:
unknown identifier 'VCFG0'
I downloaded the fix here:

Do you have a solution?
