2 ! HOMPACK90 is a suite of FORTRAN 90 subroutines for solving nonlinear
3 ! systems of equations by homotopy methods. There are subroutines for
4 ! fixed point, zero finding, and general homotopy curve tracking problems,
5 ! utilizing both dense and sparse Jacobian matrices, and implementing
6 ! three different algorithms: ODE-based, normal flow, and augmented
7 ! Jacobian. The (driver) subroutines called by the user are given in the
8 ! table below, and are well documented internally. The user need not
9 ! be concerned with any other subroutines in HOMPACK90.

基于51单片机的信号产生于周期检测
通过51单片机的外部中断接收信号，用51单片机定时器0的工作模式2记时，准确的产生一定周期的方波。同时当外部中断检测到信号的下降沿则打开定时器1记时，当第二个信号来时，关闭定时器1，读取时间，显示数据。
