在LabWindows中要求对测量时间的控制精确度很高，为此我们常用Timer控件并不能精确控制。在此例程中列举了同步定时器与异步定时器，希望对大家有帮助。-In the LabWindows called for measuring time in the control of high precision, for which we often can not be precise control Timer control. Listed in this routine of synchronous and asynchronous timer timer, want to help everyone.
