位置随着输入次数改变而改变



按下的键值将被存储到数组keystore[]中，

用户可以设置断点观测数组中的键值，也可以等程序运行完毕，再观测-this project for testing keyboard download and run the project, procedures are waiting for the keyboard input state if users press the F1, procedures for the withdrawal. Apart from the F1 press outside the Anykey at the same time, running lights will be lit, when the pop-up keyboard, the lights also criminal. If the type is 0 ~ 9 figures, then running lights out, the LED module will show the figures, show the location with the input frequency changes of pressing keys will be stored keystore [] array, Users can set breakpoints observation array keys, or other procedures completed, and then observing
