微机串行口数据采集与一组力学实验研究

Data collection by serial port in the micro-computer and a group of dynamics experiments

分别研究了微机串行通讯口和定时器原理,借助C语言编程,实现了微机对外界时间信息的数据采集.在此基础上,开展了数字毫秒计制作、重力加速度及弹性模量检测的研究.

The principles of the serial port and timer in the micro-compute are studied, and the methods to collect the data of time information by C program is introduced. Based on this, the researches on the production of mini-second counter and measurement of the acceleration of gravity and elastic modulus are carried out.
