Setting up the user_GUI.par File

We begin be describing the graphical user interface itself. For this, we develop a simple script file, the user_GUI.par file, as shown in Figure 6.1.

Line 1 is used to denote that all tokens that follow should be placed in column format. The ``n'' argument denotes that the tokens should not all necessarily have the same height. Line 2 provides the title, and is split up over two lines by the use of the `
n' command. Lines 3 through 7 are used to define each of the spin buttons, where all of them have a range of -5 to 5, have a starting value of 0, and have unique identifiers of 0-4. Finally, line 8 terminates the column. The end result will be Figure 6.2.

Lines 10-12 are required, and define the total number of inputs, outputs, and transferable data, respectively, to the user space that will be used by this controller.
