AMCI Motor Control bus

This bus can be used by any AVR microcontroller to control a motor. This is an ideal interface to

optimize the system cost and to identify the cheapest solution with the required level of

performance.

Processor boards

• The corresponding AVR processor, which handles the motor control application and the other

tasks.

• A USB interface for communication with the host using Atmel Motor Control PC software.

The USB bridge is handled by an AT90USB1287.

• A connector to plug in an optional ATAVRDB101 display and Human Machine Interface

board.

• A potentiometer for providing analog speed target to the controller.

• Programming and debugging connectors.

• The four AMCI Motor Control bus connectors.
