IIC: for using IIC interface, input the command to enable the Raspberry Pi IIC first:

sudo raspi-config

Select [Interfacing Options]-[I2C]-[Yes]-[OK]-[Finish]. Restart the Raspberry Pi when

completed these steps.

The usage of IIC ports on the expansion board is same with that of raspberry Pi, so we

will skip here.

•

UART: The usage of UART ports on the expansion board is same with that of

raspberry Pi, so we will skip here.

•

SPI： for using SPI interface, input the command to enable the Raspberry Pi IIC

first:

sudo raspi-config

Select [Interfacing Options]-[I2C]-[Yes]-[OK]-[Finish].Restart the Raspberry Pi

when completed these steps.
