| 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 networking 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. |
