(Linux-Bash)
- Give permissions to your /dev/ttyACMX (Tel-GPIO), For Example:
sudo chmod 777 /dev/ttyACM0
- Configure the serial speed:
sudo stty -F /dev/ttyACM0 115200
- Read the serial-gpio output from background:
sudo cat /dev/ttyACM0 &
- For get Help/Commands write this:
echo "-h" > /dev/ttyACM0
GPIO Read
- Get GPIO level value: (X = number of GPIO pin)
echo "@X" > /dev/ttyACM0
- Get GPIO state: (X = number of GPIO pin)
echo "?X" > /dev/ttyACM0
Write/configure GPIO
- Set GPIO as Output pin: (X = number of GPIO pin)
echo "&X" > /dev/ttyACM0
- Set GPIO as Input pin: (X = number of GPIO pin)
echo "%X" > /dev/ttyACM0
- Set GPIO level HIGH: (X = number of GPIO pin)
echo "^X" > /dev/ttyACM0
- Set GPIO level LOW: (X = number of GPIO pin)
echo "_X" > /dev/ttyACM0
