Design Guide

BiSS-C Absolute Encoder, Master-Interface Reference Design for C2000™ MCUs

Description

C2000™ microcontroller (MCU) Position Manager technology offers an integrated solution to interface to the most popular digital and analog position sensors, which eliminates the necessity for external field-programmable gate arrays (FPGAs) or application-specific integrated circuits (ASICs). The Position Manager BoosterPack™ is a flexible, cost-effective platform intended for evaluating various encoder interfaces and designed to work with multiple C2000 MCU LaunchPad™ development kits. The software of this reference design specifically targets implementation of BiSS-C™, which is a digital, bidirectional interface for position encoders. The highly optimized and easy-to-use software library and examples included in this reference design enable BiSS-C position-encoder operation using the Position Manager BoosterPack.
