This report aims to describe our bachelor degree projectin computer engineeringat Linnaeus university in Växjö. The project has been carried out on behalf of Danfoss whoapproached us with an interest in making it possible to use Raspberry Pi as an internal and external research platform, compatiblewith their development environment PLUS+1 GUIDE.We were therefore given the task to develop support for Raspberry Pi in PLUS+1 GUIDE. This would enable use of PLUS+1 GUIDE software without the use of Danfoss hardware. This report describes theimplementation of a Raspberry Pi support librarywhich had to be designed to be compatible with the PLUS+1 GUIDE software. It also describes the creation of acustomLinux distributionusing the YoctoProject, a comparison between existing solutionsand a usability test on thePLUS+1 GUIDEsoftware using the developedRaspberry Pi support library.The resultof this workis fully functioning support forRaspberry Pi packaged as a plugin that when installed in PLUS+1 GUIDE allows creation of applications for this platform in the same manner as fortheirother control systems.
