DO Usage

The usage of GPIO is as below

sudo /opt/miivii/features/gpio/bin/miivii_get_di_value <DI number>
#<DI number>: Represents the sequence number of the DI. 0 represents DI0, 1 represents DI1, and so on.
#The command return value is the current level value read from the DI, where 0 represents low level and 1 represents high level.

#Example: Read the input of DI0
#sudo /opt/miivii/features/gpio/bin/miivii_get_di_value 0

Compile sample code

cp -r /opt/miivii/features ~/
cd ~/features/gpio
sudo make;
