Description

TI provides the system solution for Industrial Communication on Sitara™ processors with Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS). This TI Design describes the integrated multi-protocol digital position encoder master interface support. The supported digital position encoder master protocols are EnDat 2.2, Hiperface DSL ® and BiSS C. The integrated multi-protocol encoder master has the benefit to work without additional field programmable gate array (FPGA), application specific integrated circuit (ASIC) and programmable logic device (PLD) while support multiple of the encoder protocols - therefore it saves cost and reduces board space. This reference design utilizes the Single Chip Drive Evaluation Board (TMDSIDK437X ) and Universal Digital Interface to Absolute Position Encoders Reference Design (TIDA-00179).

Features
  • Multi-protocol digital position encoder master interface
  • Supports EnDat 2.2, Hiperface DSL and BiSS C digital position encoder interfaces
  • For integrated single chip drives, servo drives and remote position encoder master devices
  • Digital position encoder master interface is supported by the PRU-ICSS peripheral within the Sitara AM437x processor
