TABLE 2
The function information of the pins under the SPI serial type is 6 kinds in total, as shown in table 3.
TABLE 3 Table 3
For example, the peripheral device is a carbon dioxide sensor, that is, the peripheral device needs to be connected to the carbon dioxide sensor through an SPI-type serial port to realize communication, and meanwhile, functional information of a pin of the carbon dioxide sensor is set as first pin functional information.
After the carbon dioxide sensor is connected with the multifunctional serial port of the main control chip, the main control chip starts initializing the multifunctional serial port, namely determining attribute information of the multifunctional serial port according to the function information of the UART serial port type, the IIC serial port type and the SPI serial port type pins in tables 1 to 3, so that 18 kinds of function configuration information can be determined.

The 7 th function configuration information is the first pin function information under the IIC serial port type, the 7 th identification command is the identification command corresponding to the 7 th function configuration information, and the carbon dioxide sensor cannot receive the 7 th identification command and does not reply information to the main control chip.
Similarly, identification commands corresponding to the second pin function information, the third pin function information, the fourth pin function information, the fifth pin function information and the sixth pin function information under the IIC serial port type, namely an 8 th identification command, a 9 th identification command, a 10 th identification command, an 11 th identification command and a 12 th identification command, are sent to the carbon dioxide sensor. Because the carbon dioxide sensor is of an SPI serial port type, the carbon dioxide sensor cannot receive the identification command, and does not reply information to the main control chip, and the 13 th identification command is sent to the carbon dioxide sensor.
