Pnuematics Programming Issues

[captianjroot]

Hi, my team is encountering similar problems. We're also using Java, but our code is a little different.

//this is all within our main robot class
    
    Compressor compress;
    

    public void robotInit(){

        compress=new Compressor(1,1);

    }

    public void operatorControl() {
        while(isOperatorControl()&&isEnabled()){
            

            if(!compress.enabled())
            {
                compress.start();
            }

            
        }
    }

                compress.start();
            }

            
        }
    }

This is of course assuming that the compressor is connected to a spike that is connected to relay channel 1 (on the first digital sidecar if you have more than one) and that the pressure switch is connected to digital input #1 on the same digital sidecar. Also note that you don't really need the 'enabled' clause, you can continually 'start' the compressor. It doesn't hurt anything.
This will only start the compressor in teleop.

We are having similar problems but the compressor will not turn on at all. We have the same code as the very first presented sample code. Could it be that something is wrong with our sidecar or relay?

There are several things related to the pressure switch that could keep the compressor from turning on that are not related to the Digital Sidecar or Relay. Is the pressure switch plugged into the port defined in your code? Is the pressure switch wired between signal and ground? Is the Digital Sidecar properly powered (are all 3 power LEDs brightly lit) if you remove the DB-37 cable?

[puneeth.meruva]

The led's for power to the sidecar do turn on and I believe that the pressure switch ports are correctly assigned in the code. How exactly is the pressure switch supposed to be wired?
