FD1	DSP568XX implementation

This course covers the 568XX 16-bit DSP Freescale family

Objectives The course explains how to design a 56807 based board. Optimized coding examples are described. A generic interrupt handler is introduced. The course focuses on motor driving. Practical exercices are executed on a 56807 board. This course has been delivered several times to companies developing electric engines. A lot of programming examples have been developed by ACSYS to explain how to write optimized code.   •They have been developed with CodeWarrior compiler and are executed under CodeWarrior debugger. A more detailed course description is available on request at info@ac6-training.com

Prerequisites
	Basic knowledge about signal processing and motor control.
	Knowledge of CAN bus is recommended, see our course reference CAN bus, reference IA1
