串口扩展LED时钟子程序，不含时间设定，可直接嵌入串口LED显示系统中-Serial LED clock subroutine expansion, excluding the time settings, can be directly embedded in the serial LED display system

常用串行EEPROM的编程应用，EEPROM是"Electrically Erasable Programmable Read-only"（电可擦写可编程只读存储器）的缩写，EEPROM在正常情况下和EPROM一样，可以在掉电的情况下保存数据，所不同的是它可以在特定引脚上施加特定电压或使用特定的总线擦写命令就可以在在线的情况下方便完成数据的擦除和写入-Commonly used application of serial EEPROM programming, EEPROM is Electrically Erasable Programmable Read-only (Xinhua EPROM) acronym, EEPROM under normal circumstances and EPROM, as in the case of power-down to save data , What is different is that it can exert in a particular pin on a specific voltage or use specific bus write command can be in the case of online data to facilitate the completion of the erase and write
