【摘要】 在虚拟仪器软件LabVIEW中提供的定时器的定时精度最小为1毫秒,这样,在定时精度要求更高的场合,这种定时器就不适用了。为此,本文提出一种在LabVIEW中通过它与高级语言接口来调用由C语言编写的高精度定时程序作为定时器来代替LabVIEW所提供的定时器的方法。并在实践中取得了良好的效果。更多还原

【Abstract】 The precision of tinier based on the software of virtual instrument -LabVIEW is one millisecond,so ,this kind of timer isn’ t suitable to the occasion where the precision of timer is supposed to be very high,for this ,a method by which the timer in LabVIEWE is replaced by a high precision timer program compiled by language c called through the interface offered by LabVIEW is described. Which is proved to be highly effective in practice.更多还原
