Software Usage#
System version below 5.x.x-x.x.x#
The example of using the GPIO interface is as follows.
# switch to root
sudo su -
# Read Data(DI)
cat /sys/class/gpio/<device node name>/value
# Example: cat /sys/class/gpio/gpio339/value
System version above 6.x.x-x.x.x#
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;
