【摘要】 在一般的电子产品中都会涉及到定时器、报警器、控制器等逻辑电路,人们也经常会想到经典的TTL和COMS等中小规模的逻辑电路器件,不同的器件其参数和引脚功能也不一样,在设计过程中要求设计人员必须熟悉各种不同厂家和不同型号的产品,这给设计人员带来很大的麻烦。论述了可以解决这些问题的,基于51单片机的逻辑电路的设计方法,分析了单片机的逻辑电路功能。更多还原

【Abstract】 Electronic products generally incorporate logic circuit elements such as timer,alarm and controller.TTL and COMS are classical mid-or small-scale logic circuit elements that frequently remind people.Different elements have inconsistent parameters and pins,which lead to much difficulties for designers because they have to understand products of different manufacturers and models.The author discussed the logic circuit design method based on 51 SCM,a solution for these problems,and analyzed the logic circuit function of SCM.更多还原
