DS1307是美国DALLAS公司推出的I2C总线接口实时时钟芯片，它可独立于CPU工作，不受CPU主晶振及其电容的影响，且计时准确，月累积误差一般小于10秒。芯片还具有主电源掉电情况下的时钟保护电路，DS1307的时钟靠后备电池维持工作，拒绝CPU对其读出和写入访问。同时还具有备用电源自动切换控制电路，因而可在主电源掉电和其它一些恶劣环境场合中保证系统时钟的定时准确性。DS1307具有产生秒、分、时、日、月、年等功能，且具有闰年自动调整功能。同时，DS1307芯片内部还集成有一定容量、具有掉电保护特性的静态RAM，可用于保存一些关键数据。-DS1307

欢迎来到PMOS。PMOS是一组模块，大部分用模
Welcome to PMOS. PMOS is a set of modules, mostly written in Modula-2,
to support multitasking. PMOS was designed primarily with real-time
applications in mind. It is not an operating system in the conventional
sense rather, it is a collection of modules which you can import
into your own programs, and which in particular allow you to write
multi-threaded programs.
