Run-Time Interface for Rapid Prototyping

The run-time interface for a rapid prototyping target includes:

• Supervisory logic
• The main program
• Execution engine and integration solver
• Supporting logic
• I/O drivers
• Code to handle timing, and interrupts
• Monitoring, tuning, and debugging support
• Data logging code
• Signal monitoring
• Real-time parameter tuning
• External mode communications

The structure of the rapid prototyping run-time interface, and the execution of rapid prototyping code, are detailed in Program Architecture and Models with Multiple Sample Rates.

Development of a custom rapid prototyping target generally begins with customization of one of the generic main programs, grt_main.c or grt_malloc_main.c. As described in User-Written Run-Time Interface Code above, you must modify the main program for real-time interrupt-driven execution. You must also supply device drivers (optionally inlined).
