This video tutorial introduces the use of openSYDE COMM Datapools when programming an application in "C". With an example, the programming of CAN communication between a controller and a temperature sensor using the openSYDE COM engine and COMM datapools is shown step by step. Code generated from openSYDE and its integration into the own application, as well as the display of variables at runtime of the application with openSYDE dashboards are demonstrated and in parallel the data traffic on the CAN bus is observed with the openSYDE CAN Monitor.


The participant

  • Knows the required components and tools for programming an application with "C"
  • Can program CAN communication between the controller and a temperature sensor using COMM data pools based on the template application from the Target Support Package
  • Can generate code with openSYDE and integrate it into an own application
  • Can create dashboards in openSYDE and use them to display the values of received CAN messages
  • Can use the openSYDE CAN Monitor to observe the CAN messages on the CAN bus
