1、通过定时器1的输入捕获功能,测量脉冲宽度;
2、测量脉冲18HZ到1KHZ之间;
3、按下INT1,启动测量;按下INTO,停止测量;
4、测量值利用74LS164串行显示,精度±2HZ;
-1, by the timer 1 input capture, measure pulse width 2, between the measured pulse 18HZ to 1KHZ 3, press the INT1, start the measurement press the INTO, to stop measurements 4, the measured value using 74LS164 serial display , accuracy ± 2HZ
