摘要
为了产生不同频率,不同脉宽的刺激信号,利用RS 232串行通信接口将计算机与单片机相连,计算机通过LabVIEW软件平台,对单片机发送指令参数,单片机利用接收到的指令参数产生计算机所指定的脉冲。介绍了该系统中上下位机的具体程序流程,并且完成了对整个系统的检测。通过实验证明该系统可以精确地产生所要求的脉冲波形。
With the RS 232 serial communication interface,the computer connects to the single chip. It sends the directive parameters to the single chip through LabVIEW software platform, for generating the signal with different frequency and different pulse width. The single chip generates the pulse defined by the directive parameters from computer. It introduces the both specific processes and achieves the detection of whole system. Through the experiment, the system is tested that it can generat pulse accurately all we demanded.
