Short Content: Abstract: This article proposed one kind of exchange signal zero crossing detection's electric circuit, namely the capture exchange signal's zero spot, and draws support from MSP430 the monolithic integrated circuit interior 16 timer A (Timer A) the pulse capture function then can obtain this exchange signal cycle then to be able to obtain its frequency. System's hardware part mainly by components and so on MSP430 monolithic integrated circuit as well as rectification bridge, electro-optical coupler, third-level tube constitutes; But the ...
