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

可进行不同数组联系起来的16位crc的校验.内部含有中文说明,并且已经测试过,完全正确.就是自己平时进行应用的程序.-Can be linked to a different array of 16-bit CRC checksum. Internal note containing Chinese and have been tested, absolutely correct. Is usually carried out its own application procedures.

该原代码应用在cpu(st89le516AD+)上,控制GPRS模块sim100,通过检测系统状态(通电状态,运行状态,AD采样值),通过GPRS模块的短信功能,实现无线报警.-the original source applications in cpu (st89le516AD), GPRS module sim100 control through detection system state (state electricity, running AD values), GPRS module messaging functions, wireless alarm.
