| Using CCS in MPLAB |
 Posted: Tue May 30, 2023 2:49 pm |

Looking into the possibility of using CCS within MPLAB. I understand CCS compiler users typically just #include extra C files as is the case with the legacy code that I'm using. In trying this code in MPLAB, it will not compile by dumping all C files into the source folder but will compile if I just put main in the source folder.
Problem is I get a ton of "unable to reference identifier" issues so it makes following definitions from file to file difficult. Is there a correct way to organize legacy CCS source files within the MPLAB folder structure?
I've tried putting all other C files in the library folder, but the navigation issues remain. Probably just missing something easy here. |

First, are you talking MPLAB, or MPLAB X?. Big difference.
Assuming MPLAB X.
In the project, just put the main CCS file in 'source files'. Nothing else.
Have this file #include it's component files.
Don't try to put things into the mplab folders. These are it's to control. Just
Create your own project directory, and put your files in this. Then in MPLAB,
create the 'project', and in the project tab, select the source files tab, right
click and add the main CCS file as existing item.
What is happening is that by putting them into the MPLAB folders, it is
performing an automatic 'add existing items from folder' for these files
to the project, putting them is as items to each be compiled, not building
the correct project structure.
You can correct the structure by removing every file except the main CCS
file from the Source files tab in the project. Instead drag them into the
Header Files tab. This then tells MPLAB, not to try to directly compile these
files individually. |

also...
when using MPLAB ( v8.92 is the last one I think..), there's an option called 'Build Configuration' which can be 'Debug' or 'Release'. You need to select 'Release' and then compile to create the proper code to download into the PIC for 'real World' operation. The 'Debug' option stuffs 'extra' code in so you can use their simulator and test from within the PC. |

Apologies, I'm trying to use MPLAB X. v6.05
@Ttelmah I think I follow what you're saying up until...
"Instead drag them into the Header Files tab. This then tells MPLAB, not to try to directly compile these files individually."
Maybe I don't understand what you mean by the "Header Files tab" or dragging them in. Anytime I try putting C files (by Add Existing Item) in the headers folder it tries to compile the C files just as if I put them in with main.c. Such as:
"C:\PROGRA~2\PICC\CCSCON.exe" out=""build/default/production"" main.c +EXPORT +FH +DF +CC +Y=9 +EA +DF +LN +T +A +M +J +Z -P #__18C252=1 +EXPORTD="build/default/production"
"C:\PROGRA~2\PICC\CCSCON.exe" out=""build/default/production"" Analog.c +EXPORT +FH +DF +CC +Y=9 +EA +DF +LN +T +A +M +J +Z -P #__18C252=1 +EXPORTD="build/default/production"
Compiling C:\Users\User\MPLABXProjects\project\Analog on 31-May-23 at 10:30
C:\Users\User\MPLABXProjects\project\Analog.c:30:9: Error#128 A #DEVICE required before this line
C:\Users\User\MPLABXProjects\project\Analog.o ===> 1 Errors, 0 Warnings.
Build Failed.
Compiles just fine with or without placing just true header files in the header folder, but original navigation reference issue remains. |

In the MPLAB IDE, you have 'projects'. These contain branches for
header files, libraries etc.. The point is you select the files in the
source files branch, and drag these into the header files branch. It is this
that determines how MPLAB treats the files. All files in the 'source files'
branch are compiled separately, which is not what is wanted. |

Hmm, idk.
I get the same compile error no matter whether a second c file is in projectName\Source Files or projectName\Header Files |

I've found with mplabx inc latest version, that in MPLABX projects window just have your main.c file only as the source file, then just use #include xxx.c etc in either another header file or in your main .c file.
Otherwise you will get build failed.
for example a test project I doing now works with both MPLAB 8.92 and MPLABX 6.05
my header file
StepIndex.h
| Code: |
#include "18F4431.h"
#device ADC=10
#fuses H4,NOWDT,NOPROTECT,NOLVP,DEBUG,NOLVP,NOBROWNOUT

main c file
The in MPLABX project I just add this as the main source file, I dont even add header files in the project list.
StepIndex.c
| Code: |
#include <StepIndex.h>
//when postcount equals maxcount
//interrupt, switch of PWM to stepper driver
#int_IC2QEI
void IC2QEI_isr()
{
int8 k;
PWM_OFF(stepper);
output_high(ena_pin);
POSCNT=0;
clear_interrupt(INT_IC2QEI);
}
void main(void)
{
//test code etc
}

Hope this helps. |

That's exactly right.
The only point about putting the other files into the header files list,
is it allows you to click on them there to open them and look at them. |
