Several key pints of articulated arm - cmm data acquisition system are analyzed and designed, including data synchronous latches, pair-radius readings, and coordinates real-time display. The combination of CPLD and AVR microcontroller completes the functions of grating signal faltering, 4 subdivided, discerning direction and reversible counting, and so on. According to the experiment , the data collection of the machine can be complete accurately.
