ARM单片机应用开发指南(S3C4510B)-ARM MCU Application Development Guide (S3C4510B)

本文档收录了NE555的具体的内部电路图及555的具体的应用方式,对想了解555的初学者有很大的帮助.-This document contains the specific NE555 internal circuit 555 and the specific application, right would like to know 555 beginners a great help.

仿真软件，可进行单片机等各种程序的仿真验证，大大减少焊接电路板试验的麻烦-the use of the protuse

6段数码管分别显示，时，分，秒，四个按键，K1（P0.0），K2（P0.1）， K3（P0.2），K4（P0.3），四个按键用来调时间的，按下K1，所有位都清零显示，然后按下K2，秒在闪烁，继续按K2分闪烁，不段地按K2 秒--分--时切换着闪烁，在某位闪时按下K3相应位加一，确认调整，按K4，取消调整再按K1。在K1按下以后才有调时的功能，如果K1没有按下，按别的键没有反映。这为了在加点按键功能留着用 -6 respectively of the digital control, when, minutes and seconds, four keys, K1 (P0.0). K2 (P0.1), K3 (P0.2), K4 (width), the four keys to the transfer time, press the K1, All spaces are reset, then press K2, the scintillation seconds, according to K2 pm flickered. not according to K2 of seconds-- minutes-- when switching to flicker in certain press the flash-K3 corresponding increase in a confirmed adjustment by K4, then canceled K1 adjustment. K1 in the press will only be made after the transfer of function, if K1 pressed by other key is not reflected. This points to the function keys used Retention

用单片机的I/O口象检测按键那样对其进行查询计数，在旋转速度较慢时，可以对其计数-With MCU I/O port as the detection of keys as its query count, slow rotating, you can count on their
