摘 要：为精确测量角度位置电机闭环控制，提出基于FPGA的BISS-C协议寄存器配置与数据读取方法。首先研究BISS-C协议组网方式与帧格式，阐述寄存器读写模式与数据读取模式;然后针对正余弦编码器细分芯片IC-NQC，利用FPGA芯片灵活性及并行运行效率高等特点，通过状态机设计寄存器读写电路与数据传输电路，实现对IC-NQC芯片参数配置与数据读取。采用精密摆动电机进行实验验证。实验数据为MA时钟频率5mHz，数据交换周期100kHz，满足精密摆动电机运动控制定位要求。 关键词：BISS-C;FPGA;寄存器配置;数据交换;微特电机

Abstract： In order to meet the accuracy requirements of digital galvanometer motion control system for position measurement， this paper proposes a method for register configuration and data reading of BISS-C protocol based on FPGA，conducts circuit design and experimental verification for this method. First， the BISS-C protocol n
etworking mode and frame format are studied， and its register configuration mode and data read mode are described in detail. Then， for the features of FPGA flexibility and high parallel operation efficiency， the register configuration circuit and data transmission circuit are designed by the state machine. The experimental verification is conducted by galvanometer motor. In the experiment， the MA clock frequency is 5mHZ and the data exchange period is 100kHZ. Its reliability and accuracy meet the positioning requirements of the digital galvanometer motion control system.
