本程序已经调试通过，使用I2C来从外部时钟芯片中读取并写入时间。文档包含i2c的驱动程序、时钟芯片的读与写、以及使用定时器中断产生脉冲来模拟gps对时。-This procedure has been debugging through the use of I2C chip from the external clock time to read and write. Document contains the i2c driver, the clock read and write chip, and the use of the timer interrupt to simulate the pulse generated when the gps on.

利用动态扫描和定时器1在数码管上显示 出从765432开始以1/10秒的速度往下递减 直至765398并保持显示此数，与此同时利 用定时器0以500MS速度进行流水灯从上至 下移动，当数码管上数减到停止时，实验 板上流水灯也停止然后全部开始闪烁，3秒 后（用T0定时）流水灯全部关闭、数码管上 显示出"HELLO"。到此保持住。 设晶振频率为12MHz。-The use of dynamic scanning and Timer 1 in the digital control to show from the beginning of 765,432 to 1/10 seconds until the speed of descending down 765,398 and maintain display this number, at the same time the use of Timer 0 to 500ms the speed of light from the flowing water to Under the move, when reduced to a few digital tube stop, the experiment on-board water stop and then all the lights started to flicker, 3 seconds later (T0 regularly used) closed water lights, digital tubes show
