你自己用keil软件调就行了！
无论是对DS1302写还是读 *** 作, *** 作时RST必须置"1"；CLK和DAT的时序非常类似于I2C总线 *** 作，CLK是串行通讯的时钟信号，由单片机提供，DAT为双向数据信号，具体时序需参考DS1302编写。
以上就是关于单片机汇编语言实现实时时钟，不知道我的哪里出错了，请大家帮忙看看全部的内容，包括:单片机汇编语言实现实时时钟，不知道我的哪里出错了，请大家帮忙看看、跪求 51单片机+12864液晶+1302时钟制成的万年历c程序、求单片机 实时时钟 电路 图和配套代码等相关内容解答，如果想了解更多相关内容，可以关注我们，你们的支持是我们更新的动力！
