时钟程序,大家是否想到用定时器，对，也可用定时器的中断来处理，这样的程序我想不用我说了吧！

你们可自己发辉下，本程序采用外元件DS1302时钟IC，使用此IC不增加系统资源，要时钟时直接去读取就可以了

本IC跟ADC0831一样以串口方式传送数据，不同的是协议，只要你读懂它的串口协议，就可以用P口来模拟协议进行

，这样更能使你对传送数据协议的了解，在看本程序之前，先看看芯片的串口协议*/-Clock process, with everyone thought Whether or not the timer, right, can also be used to deal with the timer interrupt, so that the procedures I do not think so I said it! Your own hair can be under-hui, the procedures for the use of external components DS1302 Clock IC, this IC does not increase the use of system resources, go directly to the clock can be read on the same IC with the ADC0831 to serial transmission of data, are a different protocol As long as you read its serial protocol, it can be used to simulate the protocol P to the mouth, so more can you transmit data to know the protocol, look at this process, first take a look at the serial port chip protocol* /
