EnDat 2.2 Absolute Encoder Master Interface Reference Design for C2000 MCUs

TIDM-1008

Design files

Overview

C2000 Position Manager technology offers an integrated solution to interface to digital absolute encoders as well as resolvers and SINCOS transducers eliminating the need for commonly used additional circuits in industrial inverter and servo drives. The PositionManager BoosterPack, described by TIDA-1008, is a flexible low voltage platform intended for evaluating various encoder interfaces and designed to work with Position Manager-enabled LaunchPads such as the LAUNCHXL-F28379D. The highly optimized, easy-to-use library and example software delivered with TIDA-1008 support the EnDat 2.2 and EnDat 2.1 standard.

Features

Flexible low voltage design supports multiple absolute encoder interfaces as well as Resolver and SINCOS sensors
TIDA-1008 works with C2000 Position Manager-ready MCUs (via LaunchPad) for Integrated EnDat2.2 and EnDat 2.1 digital protocol solution
Easy interface to EnDat2.2 commands via software driver functions and data structures
C28x optimized CRC algorithm and data unpacking
Up to 8 MHz EnDat clock supported. Operation verified for up to 100m cable length
TIDM-1008 includes an evaluation board and a software example showcasing the EnDat22 Software library
