The super-loop example-program

The present chapter’s example-program is a timed super-loop. (We’ll refer to it here as simply the example-program.) The timed super-loop was described in the prior chapter, in pseudo-code format, and it is shown below. The example-program implements that pseudo-code. This section explains how the example-program works, and how to run it on the dev-board. How to create the program will be described later in the chapter.

// Start the super-loop's repeating timer
start_timer();
while(1)
{
    func1();
    func2();
    func3();
    // Sleep until the timer's period expires
    disable_interrupts();
    while( !timer_expired_flag )
    {
        sleep();
        enable_interrupts();
        disable_interrupts();
    }
    enable_interrupts();
}

The super-loop example-program is described in the following sections:
