8. Motor Control Software

The Drive-on-Chip Design Example motor control software is in C, runs under the Micrium µC/OS-II real-time Operating System on the Nios II processor, and is in two parts.

The main program covers the initialization, status reporting, and communication functions. The ISR covers the real-time aspects of running the motor control FOC algorithm. The system.h header file is generated from the Qsys system via the .sopcinfofile, which contains a description of the system interconnectivity and module base addresses.
