(1) 设置DMA通道，控制ADC测量内部温度传感器温度；
(2) 每次自动测量50次；
(3) 设置DMA通道，控制串口发送字符串：NO. 01 temperature is:xx℃；NO. 02temperature is:xx℃；依次类推，其中包含序号和温度值；
(4) 串口接收也采用DMA的方式，串口助手向单片机发送的数据形式是：“xxxxxxxxxxxxxxstopxxxxxxxxxxxx”；“xxxxxxxxxxxxxxgoxxxxxxxxxxxx”；xxx是随机字母，长短不定，但其中包含stop和go等控制字；单机接收到stop指令后，停止AD采样和串口发送；接收到go指令后继续AD采样和发送；
通过正点原子的代码进行修改，已调试，正常运行
