Update Paths for Source and Header Files

Step 5 of 8 in Create Custom Device Driver Block for Arduino Library

1. In the MATLAB^® editor, open the colorSensor.m file.

2. Update the BuildInfo method with the following code.

   methods (Static)
       ...
       function updateBuildInfo(buildInfo, context)
           if context.isCodeGenTarget('rtw')
               % Update buildInfo
               srcDir = fullfile(fileparts(mfilename('fullpath')),'src');
               includeDir = fullfile(fileparts(mfilename('fullpath')),'include');
               libDir =  fullfile(fileparts(mfilename('fullpath')),'libraries');
   
               % Include header files
               addIncludePaths(buildInfo,includeDir);
               addIncludePaths(buildInfo,libDir);
   
               % Include source files
               addSourceFiles(buildInfo,'colorSensor.cpp',srcDir);
               addSourceFiles(buildInfo,'Adafruit_TCS34725.cpp',libDir);
   
               boardInfo = arduino.supportpkg.getBoardInfo;
       
               switch boardInfo.Architecture
                   case 'avr'
                       % Add SPI Library - For AVR Based
                       ideRootPath = arduino.supportpkg.getAVRRoot;
                       addIncludePaths(buildInfo, fullfile(ideRootPath, 'hardware', 'arduino', 'avr', 'libraries', 'SPI', 'src'));
                       srcFilePath = fullfile(ideRootPath, 'hardware', 'arduino', 'avr', 'libraries', 'SPI', 'src');
                       fileNameToAdd = {'SPI.cpp'};
                       addSourceFiles(buildInfo, fileNameToAdd, srcFilePath);

                       addIncludePaths(buildInfo, fullfile(ideRootPath, 'hardware', 'arduino', 'avr', 'libraries', 'Wire', 'src'));
                       addIncludePaths(buildInfo, fullfile(ideRootPath, 'hardware', 'arduino', 'avr', 'libraries', 'Wire', 'src', 'utility'));
                       srcFilePath = fullfile(ideRootPath, 'hardware', 'arduino', 'avr', 'libraries', 'Wire', 'src');
                       fileNameToAdd = {'Wire.cpp'};
                       addSourceFiles(buildInfo, fileNameToAdd, srcFilePath);
                       srcFilePath = fullfile(ideRootPath, 'hardware', 'arduino', 'avr', 'libraries', 'Wire', 'src', 'utility');
                       fileNameToAdd = {'twi.c'};
                       addSourceFiles(buildInfo, fileNameToAdd, srcFilePath);

                       % Add SPI Library - For SAM Based
                       libSAMPath = arduino.supportpkg.getSAMLibraryRoot;
                       addIncludePaths(buildInfo, fullfile(libSAMPath, 'SPI','src'));
                       srcFilePath = fullfile(libSAMPath, 'SPI','src');

                       addIncludePaths(buildInfo, fullfile(libSAMPath, 'Wire', 'src'));

                       libSAMDPath = arduino.supportpkg.getSAMDLibraryRoot;
                       addIncludePaths(buildInfo, fullfile(libSAMDPath, 'SPI'));
                       srcFilePath = fullfile(libSAMDPath, 'SPI');

                       addIncludePaths(buildInfo, fullfile(libSAMDPath, 'Wire'));
