5.2.1 SHELL programs and Trajexia Studio
Trajexia Studio helps the user to create a proper SHELL program.
When a new project is created, a SHELL program with the basic structure is
created automatically (see 5.1.1).
When you define the hardware and set the parameters for the application,
you can select to add your changes to the SHELL program so, the user do
not have to type it manually.
Use the example SHELL program as a template to start, stop and reset your
machine and adjust the rest of the SHELL program according to the
requirements.
The SHELL program is automatically selected to start at POWER-ON in low-
priority task 1.
Example
The example program below is a typical SHELL program created by Trajexia
Studio.
