Abstract: This design uses the one-chip microcomputer to be controlled gathering of logical signal levels of 8 tunnels, uses CPLD's chip of EDA'stechnical design to the logic signal processing and control scanning to the lattice signal and the result of display analysis on the oscillograph , usesthe interrupt mode exchange data between one-chip microcomputer and CPLD. This design has 1 and 3 grade of method of activation, trigger wordseat display and time to be marked thread display etc. merit ability.
