Compiling the Software

Overview

This guide explains how to compile the software for the PIC18F67J94 microcontroller using PIC C CCS v5.050. Note that previous BIRDS projects have used v5.076, so compatibility differences may exist.

Before you start

Before compiling the software, ensure:

  • You have installed PIC C CCS v5.050 (or an alternative compatible version).
  • The source code is available and properly configured.
  • The necessary compiler settings are adjusted for your specific board.

Compiling the Software

  1. Open the PIC C CCS Compiler

    Launch the CCS Compiler software and ensure your project directory is accessible.

  2. Load the Project File

    • Navigate to File > Open Project.
    • Select the .prj file corresponding to your board.

  3. Verify Compiler Settings

    • Ensure the correct microcontroller (PIC18F67J94) is selected.
    • Check that the compiler is set to the correct optimization and warning levels.
    • Confirm the include paths and library dependencies are correctly configured.

  4. Make Necessary Code Modifications

    If specific board settings need to be changed, update the following sections in the code:

     // Example: Define board-specific configurations
 #define BOARD_VERSION "v1.0"
 #define USE_EXTERNAL_CLOCK 1

  5. Compile the Code

    • Click on Compile or use the shortcut (Ctrl + F9).
    • The compiler will process the files and generate the necessary binaries.

  6. Check for Errors and Warnings

    • If there are errors, review the error messages and adjust the code accordingly.
    • Warnings should be noted but may not always require changes.

  7. Verify the Output Files

    After a successful compilation, confirm the following output files are generated:

    • .hex file (for flashing onto the microcontroller)
    • .lst file (assembly listing)
    • .sym file (symbol table)
