我主要是通过串口来实时采集GPS得同步数据,频率20HZ,而且数据长度(均大于200个字符)是变化的,每次都要提取里面有用的数据。所取数据用于汽车试验参数。
本人分别采用两种方式来实时读取串口数据:一种是大家常用的VISA控件; 另一种是调用Mscomm。本人在使用中感觉后一种通讯方式很好!
-I mainly collected through the serial port in real-time GPS data were synchronized, frequency 20HZ, and the data length (all greater than 200 characters) is the change, inside each time extracting useful data. The obtained data are used for automotive test parameters.
I were used in two ways to read data from serial port in real-time: one is our common VISA controls the other is called Mscomm. I use the feeling of a good means of communication!
