FIFOs
The program fifo_app.c below illustrates how to communicate with a real-time task using real-time FIFOs. The fifo_app.c is ran interpretively under Ch while the real-time task, fifo_task.c, is loaded as a module into the real-time kernel. This program can be found in the directory CHHOME/package/chrtai/demos after installation of the Ch RTAI package, where CHHOME is the home directory in which Ch is installed.
A GTK GUI has been created for the application. A snapshot of the application is shown below.
This demo does not require the installation of Ch RTAI in order to work.
