Tutorial One

This tutorial creates simplified versions of the Tools Demo (gtksimple.g and phsimple.g). With a single command, the simple demo starts the Cascade DataHub, the PID Emulator, the Monitor (in Linux and QNX), and the DataHub Viewer. The code for the PID Emulator and Monitor is covered in this tutorial, as well as a couple of common functions. The rest of the code for the Tools Demo is explained in Part III, “Tutorial Two”.
