定时同步是UWB通信系统中至关重要的问题，定时偏差和抖动将严重影响接收机性能。一般定时同步分为捕获和跟踪两个阶段。在捕获阶段，要求接收机快速搜索信号到达时间，并根据搜索结果调整接收机定时.-Timing Synchronization UWB communication systems is of vital importance to the issue, timing error and jitter will seriously affect the receiver performance. Timing Synchronization generally divided into two stages to capture and track. In the capture stage, the request receiver Quick Search signal arrival time, and adjust search results according to the receiver from time to time.

采用PIC16C54单片机实现车内空气的运动控制
用PIC16C54来实现汽车空调的动作控制（扫风、除霜、点火、循环扫风。。。），因16C54内存较小，故采用汇编来实现，其中的定时编程，颇费了我一番心思，希可供借签！-Using PIC16C54 to achieve motion control in vehicle air-conditioners (sweep wind, defrost, ignition, cycle the wind sweep 。。。), due to the smaller memory 16C54, it used to realize a compilation, of which the regular programming, a lot of my remarks thinking, by signing for Greek!

PWM 控制 LED 灯渐亮渐灭程序
适用 ME300B 开发系统
利用定时器控制产生占空比可变的 PWM 波
按K1，PWM值增加，则占空比减小,LED 灯渐暗。
按K2，PWM值减小，则占空比增加,LED 灯渐亮。
当PWM值增加到最大值或减小到最小值时，蜂鸣器将报警。-PWM control of LED lights getting brighter gradually eliminate procedures apply ME300B development system the use of timer control which produces a variable duty cycle PWM wave by K1, PWM value is increased, then the duty cycle decreases, LED lights dimming. According to K2, PWM value is reduced, then the duty cycle increases, LED lights gradually brighter. When the PWM value is increased to maximum or reduced to minimum, the buzzer will alarm.
