Nettet51单片机秒表计时器课程设计报告 (含C语言程序) 设计一个秒表计时器，在51单片机的控制作用下，采用4个LED数码管显示时间，计时范围设置为00.0~60.0秒，即精确到0.1秒，用按键控制秒表的“开始”、“暂停”、“复位”，按“开始”按键，开始计时；按“暂停 ... Nettet外部中断配置：int0对应p3.2(int1为p3.3)，it0选择触发方式(一般置1,选择下降沿触发)，ex0置1允许cpu识别int0中断，ea置1中断总开关打开。 当P3.2 出现中断信号时，中断标志IE0置1，CPU 执行中断函数：void 自定义函数名() interrupt 0（eg:interrupt 是关键字，后面的“0”是中断号）。
