Abstract

Aiming at the lack of MCU`s I/O number,this paper proposed an CPLD and MCU application to laser screen coordinate measurement.The CPLD was used as the coordinate acquisition and collection equipment,MCU controled the CPLD,and received,processed,and displied the data from CPLD.The experiment of coordinate measurement of 7.62 mm projectile was carried out,the result proved that the CPLD and MCU not only inherited the merits of the optical-electrical target,but also solved the problem of I/O deficiency and processing speed slowness of traditional MCU.This method can meet the demands of large area target and running fire for the acquisition of projectile coordinate.It was convenient in adjustment,high sensitivity,fast response speed,and can be joint with the laser screen.
