2. Hello World Code Example
2.1 Hello World Operating Task
This section gives a small introduction about the operating and timer tasks. It should give the user a basic
understanding on how these tasks work via a hello world implementation. First, operating tasks will be
presented.
Note: main.c is required to start up the freeRTOS operating system. All code implementations will take place
in additional interface header .h files and implementation .c files. Please refer to the section 5.3 how to add
new interfaces to the XDK.
