Design of a Communication Interface between the Controller and the Galvanometer

Abstract:

Article Preview

In a laser marking system, a laser marking controller should be designed to control several galvanometers through a certain interface using a certain protocol, such as the XY2-100 or SPI. The selection of the protocol depends on the configuration of the laser marking system. Using different protocols makes the controller design provide two types of interfaces. If different protocols have their own physical interfaces, the circuit becomes more complicated. In order to decrease the number of physical interfaces and ensure the protocol compatibility at the same time, two protocol signal generator modules based on FPGA are provided and the output signals of the two modules share the same physical interface, and only one of them can be chosen according to a flag set by users. This design makes the circuit simpler and decreases the design cost.
