A Low Frequency Phase Measuring Instrument Based On MSP430F413 |
| |
| Abstract: | A design method of low frequency phase measuring instrument based on MSP430F413 is mainly introduced in this paper. After being waveshaped, the signal to be measured is transmitted into the TA1 or TA2 port of Timer A of the MSP430F413 chip. By the use of the capture function of Timer A, the frequencies and the phase difference between two different signals with the same frequency can be measured. The results of measurement can be displayed on the LCM12864.The measuring range is from 10 to 1000 Hz. |
