UCOSII在mcs12dg128上的移植，有包括初始化任务，红绿灯，互斥信号量，建立统计任务，空闲任务，任务额外信息，消息队列在内的6个工程。内容十分详尽，适合UCOS的学习。不过因为文件过多，低license无法编译，请自行申请license(UCOSII at mcs12dg128 on the transplant, including initialization tasks, the traffic lights, mutual exclusion semaphores, set up statistical mission, free mission, tasks, additional information, message queues, including six works. Very detailed study of the fit uCOS. However, because file too large, low-license can not compile your own application for license)

详细阐述了脉冲信号的产生和整形，介绍集成定时电路CC7555的内部结构和典型应用，便于新手理解，希望给大家带来帮助(A detail instruction of pulsing signal. CC7555 is also introduced, it is very suitable for beginners.May it be hopeful. )

stm32F103 TIM1输出7路PWM STM32F103ZET6总共有8个定时器，TIM1和TIM8是高级控制定时器，TIM2、3、4、5是通用定时器， TIM6和TIM7是基本定时器。 本例程实现高级控制定时器TIM1总共7个功能引脚输出PWM波形。(STM32F103ZET6 has 8 timers in total, TIM1 and TIM8 are advanced control timers. This routine implements an advanced control timer TIM1 that outputs PWM waveforms for a total of 7 function pins.)
