C Language Code Running on the C-Motion 

Engine

One of the most powerful features of the software libraries provided for the Prodigy/CME PC/104 card is that the 
code sequence used to accomplish a specific function such as accessing the dual-ported RAM, or sending commands 
to the Magellan Motion Processor, does not change whether the code is compiled for execution on the host controller, 
or for execution on the C-Motion Engine.

This allows motion control applications developed using C-Motion on a host computer to be easily ported to the 
Prodigy/CME PC/104 card. The C-Motion Engine provides a C programming environment for motor control 
without requiring the time-consuming development of the entire embedded framework. Only the part unique to a 
specific motor control application must be provided.

For a complete description of the C-language commands supported by the Prodigy/CME PC/104 card see the 

Prodigy/CME Programmer’s Reference

. For a complete description of Magellan C-Motion commands, see the 

Magellan 

Motion Processor Programmer’s Command Reference

. For a detailed description of how to develop, download, and monitor 

user application code for the C-Motion Engine see the
