| Abstract: | A frequency measuring system based on MSP430F449 and vibrating-wire sensors,including the design of hardware and the flow of software is presented. This design uses photocoupler relay and intermittent stimulate mode to excite vibrating-wire sensor,resulting in good excitation effect,in addition uses the timer A and timer B in MCU,MSP430F449,for realizing the equal-precision frequency measuring,resulting in wide range and high precision of frequency measurements. The monitored data are directly stored in the... |
