| Abstract: | The paper presented a technique method about a high precision testing frequency, counting and timing system. The system can fulfill the request of the measure to frequency,count and time by programmable counter array and the counter of C8051F020. The hardware and software was expatiated in detail, and applicant this system in the flowmeter calibrator measurement system. The result shows that the system can achieve measurement requirement. The system has the advantages of high-precision,highly integrated,low cost,low power consumption. |
