如果是用pc的串口传输数据就好办了,可以安装一个串口监视工具(如AccessPort)。电脑串口一般是2、3、5三根线通讯,2是txd,3是rxd,5是GND,但是电脑的逻辑电平与单片机的逻辑电平不同,具体看串口通信协议,网上很容易搜到。
IIC总线上的数据可以通过示波器查看,两个探头,一个连接clk,另一个连接sda,IIC通信时可以观察到传输的数据。 -If you are using pc' s serial port to transfer data much easier to handle, you can install a serial port monitoring tool (such as AccessPort). Computer port is generally 2,3,5 3 line communication, 2 is the txd, 3 is rxd, 5 is GND, but the computer and the microcontroller logic levels of different logic level, specifically to see the serial port communication protocols, the Internet is easy to search . IIC bus data can oscilloscope view, the two probes, a connection clk, another connection sda, IIC communication can be observed when the data transmitted.
