说明：  STM32+ads1118采集程序，已调通(STM32+ads1118 sample program)

利用kinect获取原始的音频波形，得到四声道的pcm波形。(Use kinect to get the original audio waveform, get pcm waveform four channels.)

通过设置参数可以输出正弦波、三角波、锯齿波等等.(By setting parameters can be output sine wave, triangle wave, sawtooth wave and so on.)

说明：  东西、南北两干道交于十字路口，各干道有一组红、绿、黄三个指示灯，指挥车辆和行人安全通行。南北方向为主干道，通行时间为35秒；东风方向为支干道，通行时间为25秒。通行时间最后3秒，绿灯灭，黄灯闪烁，黄灯闪烁完毕变更通行车道。通行时间由数字显示器显示，黄灯3秒闪烁不单另计时。 特殊情况控制通行方式控制，用按键开关K1控制主道通行，支道禁行，K2控制支道通行，主道禁行，特殊情况控制通行放行。 有紧急情况时用按键开关K3控制两道均为红灯。(The east-west and North-South arterial roads intersect at the intersection. Each arterial road has a group of red, green and yellow indicator lights to guide vehicles and pedestrians to pass safely. The north-south direction is the main road with a traffic time of 35 seconds; the east direction is the branch road with a traffic time of 25 seconds. At the last 3 seconds of the traffic time, the green light is off, the yellow light is flashing, and the yellow light is flashing to change the traffic lane. The traffic time is displayed by the digital display, and the yellow light flashes for 3 seconds, not only for another time. Under special circumstances, control the way of passage. Use key switch K1 to control the passage of main road, Branch Road, K2 to control the passage of branch road, main road and special circumstances to control the passage and release. In case of emergency, use key switch K3 to control two red lights.)

基于单片机学习的直流电机调速，用C语言编程的(Microcontroller based DC motor speed of learning, using the C language programming)

Led based voltage meter use pic16f676

说明：  TM4C123G编程的Modbus辅助网络(Modbus slave using tm4c123g)

刚做完的lcd12864 全中文多级菜单驱动程序．自认为通用性很好．在wave下编译通过．(Lcd12864 just finished the whole Chinese menu-driven multi-level procedures. Since the general good think. In the wave passed under the compiler.)

说明：  针对stm32裸机的先入先出队列，在串口接收缓存中有很大作用(First in first out queue for STM32 bare metal)
