CC2530串口控制LED灯奇怪玩法
实验目的：CC2530用串口从上位机发送16进制命令代码来控制LED3、4、5、6并返回相应动作
一、串口设置
设置串口调试工具
设置接收区和发送区
举例：发送0x01的命令
二、串口发送相应命令
命令代码1:0x01 ==> LED3亮,返回“LED3 is open!"
命令代码2:0x02 ==> LED4亮,返回“LED4 is open!"
命令代码3:0x03 ==> LED5亮,返回“LED5 is open!"
命令代码4:0x04 ==> LED6亮,返回“LED6 is open!"
命令代码5:0x05 ==> LED3、4亮,返回“LED3 and LED4 is open!"
命令代码6:0x06 ==> LED5、6亮,返回“LED5 and LED6 is open!"
命令代码7:0x07 ==> LED3、5亮,返回“LED3 and LED5 is open!"
命令代码8:0x08 ==> LED4、6亮,返回“LED4 and LED6 is open!"
命令代码9:0x09 ==> LED3、4、5跑马灯从左到右,返回“LED3、LED4、LED5 rush rush!"
命令代码10:0x0a ==> LED3、4、5跑马灯从右到左,返回“ rush rush LED3、LED4、LED5！"
命令代码11:0x0b ==> LED4、5、6跑马灯从左到右,返回“ LED3、LED4、LED5 rush rush！"
命令代码12:0x0c ==> LED4、5、6跑马灯从右到左,返回“ rush rush LED3、LED4、LED5！"
命令代码13:0x0d ==> LED3、4、5、6跑马灯从左到右,返回“LED3、LED4、LED5、LED6 rush rush！"
命令代码14:0x0e ==> LED3、4、5、6跑马灯从右到左,返回“ rush rush LED3、LED4、LED5、LED6！"
命令代码15:0x0f ==> LED3、4、5、6闪烁,返回“LED3、LED4、LED5、LED6 flicker！"
命令代码1:0x11 ==> LED3灭,返回“LED3 is closed!"
命令代码2:0x12 ==> LED4灭,返回“LED4 is closed!"
命令代码3:0x13 ==> LED5灭,返回“LED5 is closed!"
命令代码4:0x14 ==> LED6灭,返回“LED6 is closed!"
命令代码5:0x15 ==> LED3、4灭,返回“LED3 and LED4 is closed!"
命令代码6:0x16 ==> LED5、6灭,返回“LED5 and LED6 is closed!"
命令代码7:0x17 ==> LED3、5灭,返回“LED3 and LED5 is closed!"
命令代码8:0x18 ==> LED4、6灭,返回“LED4 and LED6 is closed!"
命令代码9:0x19 ==> LED3、4、5跑马灯灭,返回“LED3、LED4、LED5 is closed!"
命令代码10:0x1a ==> LED3、4、5跑马灯灭,返回“LED3、LED4、LED5 is closed！"
命令代码11:0x1b ==> LED4、5、6跑马灯灭,返回“LED3、LED4、LED5 is closed！"
命令代码12:0x1c ==> LED4、5、6跑马灯灭,返回“LED3、LED4、LED5 is closed！"
命令代码13:0x1d ==> LED3、4、5、6跑马灯灭,返回“LED3、LED4、LED5、LED6 is closed！"
命令代码14:0x1e ==> LED3、4、5、6跑马灯灭,返回“LED3、LED4、LED5、LED6 is closed！"
命令代码15:0x1f ==> LED3、4、5、6灭,返回“LED3、LED4、LED5、LED6 is closed！"

总结
本章节运用到了时钟设置、串口通讯、引脚定义、定时器1设置的操作，写的不是很好，一部分执行的功能分成了两部分，一个是定时器中断里面，一个是串口中断里面，希望广大的网友提供一些宝贵的改进意见，一起来学习单片机哦哦哦!!!
