这个是我写的单片机PWM脉冲调制程序，希望对初学者有点点帮助！(This is what I write microcontroller PWM pulse modulation program, hope for beginners who are little help)

stm8s003写的电压表程序，压缩包包含原理图与源代码，IAR环境编译(Stm8s003 write the voltmeter program, compressed package contains the schematic and source code, IAR environment compiler)

说明：  (一) 设计交通灯控制的软硬件，实现交通灯的控制。 (二) 交通灯的红、绿、黄灯亮灯时间可以通过键盘设定。 (三) 交通灯控制要有直道、弯道及非机动车的通行、停止控制。 (四) 在某一方向通车或停车时，要有动态的指示，消除司机的烦躁情绪。 (五) 红灯停、绿灯行、黄灯停止未过线的机动车和停止方向的预启动。 (六) 黄灯亮的时间不可改变，预定5秒钟。 ((A) the traffic light control software and hardware design to realize the control of traffic lights. (B) the traffic lights red, green, yellow light time can be set via the keyboard. (C) of the traffic light control should be straight, curved and non-motor vehicle traffic, and stop control. (D) the direction of traffic or parking in a while, there must be a dynamic instructions, eliminating the driver' s irritable mood. (E) red light stop, green, and yellow lines to stop the vehicle has not been the direction of the pre-start and stop. (F) yellow light time can not be changed, scheduled for 5 seconds.)
