FreeRTOS实验15-1 FreeRTOS软件定时器实验
硬件资源:
1,DS0(连接在PA8)，DS1(连接在PD2上)
2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面)
3,ALIENTEK 2.8/3.5/4.3寸LCD模块(仅支持MCU屏)
4,按键KEY0(PC5)/KEY1(PA15)/KEY_UP(PA0,也称之为WK_UP)
实验现象:
通过按键KEY_UP可以控制定时器AutoReloadTimer_Handle的开启，这个是
周期定时器，一旦开启就会不断的运行，直到按下KEY1将其关闭。按下KEY0
可以打开定时器OneShotTimer_Handle，这是个单次定时器，只会运行一次，
运行周期到了以后就会停止运行，除非按下按键KEY0将其再次开启。(Hardware resources:
1, DS0 (connected to PA8), DS1 (connected to PD2)
2. Serial port 1 (baud rate: 115200, PA9/PA10 connected on board USB to serial chip CH340)
3, ALIENTEK 2.8/3.5/4.3 inch LCD module (only supporting MCU screen)
4. Keyboard KEY0 (PC5)/KEY1 (PA15)/KEY_UP (PA0, also known as WK_UP)
Experimental phenomena:
The timer AutoReloadTimer_Handle can be turned on by keying KEY_UP. This is
The periodic timer will run continuously once it is turned on until KEY1 is pressed to turn it off. Press KEY0
You can turn on the timer OneShotTimer_Handle, which is a single timer and only runs once.
The run cycle will stop after that unless KEY0 is pressed to turn it on again.)

Trafficlightcontroller
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.)
