User-Written Run-Time Interface Code

Most of the run-time interface is provided by Real-Time Workshop. You must implement the following elements:

• A timer interrupt service routine (ISR). The timer runs at the program's base sample rate. The timer ISR is responsible for operations that must be completed within a single clock period, such as computing the current output sample.The timer ISR usually calls the Real-Time Workshop supplied function, rt_OneStep.
• The main program. Your main program initializes the blocks in the model, installs the ISR, and executes a background task or loop. The timer periodically interrupts the main loop. If the main program is designed to run for a finite amount of time, it is also responsible for cleanup operations - such as memory deallocation and masking the timer interrupt - before terminating the program.
• Device drivers to communicate with your target hardware.
