Abstract: The invention provides a method for realizing a position sensor interface supporting various sensor communication protocols. The method can realize a function of supporting a TAMAGAWA interface data transmission protocol, a Biss interface data transmission protocol, an SSI interface data transmission protocol and an EnDat interface data transmission protocol and intelligently identifying any one of the four sensor transmission protocols. The method brings great convenience to field debugging of extensive customers and field technicians and has very high practicability.
TL;DR: This paper discusses how to operate using a microcontroller unit (MCU), a field-programmable gate array (FPGA), and a RS422 transceiver chip without using a slave module and solves the problem by using the FPGA.
Abstract: This paper addresses issues that occurs when using an asynchronous serial communication mode instead of encoder communication, such as (bidirectional/serial/synchronous) BiSS communication in an encoder system, and operation without using a slave module when using BiSS communication. Therefore, this paper discusses how to operate using a microcontroller unit (MCU), a field-programmable gate array (FPGA), and a RS422 transceiver chip without using a slave module. It also explains the problems that arise when using the MCU and solves the problem by using the FPGA. The effectiveness of the proposed method is demonstrated by the experimental results.
