【摘要】 MCS－51单片机在工业中应用极为广泛，但其定时计数功能却较差。从而限制了它的应用。本文提出了一种将Z80－CTC应用于MCS－51单片机系统中的接口电路，并从理论和实验上证明了本方法的正确性。更多还原

【Abstract】 The single chip computer MCS-51 is extremly widely used. but its timing function is not so gwt. so this gives a limitation on its application The article will talk about the wey of how to intor-Parce the circuit of Z80-CTC with the single ship motor MCS-51, It will prove that the methed is quiterelinble both form the theory and practice.更多还原
