Hello. I’m new to programming and was wondering how programming pneumatics is done with easy c. Sample codes and pictures certainly help. Thanks 
I’m assuming you want to use a joystick button to activate the pneumatic device.
You can use a “joystick to digital output” command. Select the button and output port. When you press the button it will activate the pneumatic. Releasing the button it will deactivate the pneumatic.
Also, a “joystick to digital latch” command will work as a 1 time push button to activate the pneumatic device. Pressing the same button a second time will deactivate the pneumatic device.
