数字钟的显示程序以及一个检验显示的程序，用在8051或8031-digital clock display procedures and an examination revealed that the procedures used in 8051 or 8031

Point RTOS 主要是一个针对小系统开发而设计的实时操作系统。 目前，Point RTOS 仅提供对51系列及其扩展系统单片机的支持， 针对51内核函数不能重入以及51单片机的内存空间管理方式等因素， RTOS放弃了抢先式内核的调度，而使用了时间片的调度方式，除非任务主动放弃， 否则任务将独占CPU一直运行，因而任务中必须完成对本次操作的时间片设置，即等时间的设置。-Main Point RTOS is a small system development and design of real-time operating system. At present, Point RTOS only provide for 51 series and its expansion of the system single-chip support for 51 core function should not re-entrant, as well as 51 single-chip memory space management and other factors, RTOS abandoned preemptive kernel scheduling, the use of a scheduling time slice manner, unless voluntarily chose to abandon the mission, or mission will be exclusive CPU has been running, which must be completed in the mission of this operation time slice settings, that is, the time settings.
