【Abstract】 The paper introduced the application of a new type of 8-bit LED display control driver MAX7219 in DXD packaging machine and its working principle.At the same time,the designing method for hardware and software was indicated.This serial packaging machine was unstable during working,so we designed several measures to eliminate interference and the design has been checked by more than ten plants.The practice proves that the design is feasible,and the control reliability and stability of the packaging machine was improved greatly.The elementary experiments indicated that adopting this design,the increase of productivity was more than 8%.更多还原
