DriverStation User Message Problem

[JewishDan18]

I had a similar problem (not with old code though). Are you using this method of sending messages?

DriverStationLCD.getInstance().println(DriverStationLCD.Line.kUser2, 1,"your message");

Do you have this bit of code after you've sent all your messages?

DriverStationLCD.getInstance().updateLCD();

Ah yeah, I use those methods. They were on the old code, but they don't seem to work.

So this is the code I currently have. Have you got your DriverStation to print any user messages?

package edu.wpi.first.wpilibj.templates;


import edu.wpi.first.wpilibj.IterativeRobot;
import edu.wpi.first.wpilibj.AnalogChannel;
import edu.wpi.first.wpilibj.DriverStationLCD;

public class RobotTemplate extends IterativeRobot {


AnalogChannel b_sonar;
DriverStationLCD b_LCD;
static final int sonarPort = 6;
long lSonarCount;

public void robotInit() {
b_sonar = new AnalogChannel(sonarPort);
b_LCD = DriverStationLCD.getInstance();
b_LCD.updateLCD();
}


public void autonomousPeriodic() {
b_sonar.getVoltage();

}


public void disabledInit(){
b_LCD.println(DriverStationLCD.Line.kMain6, 1, "Print");
}

public void teleopPeriodic() {
//lSonarCount = b_sonar.getAccumulatorCount();
b_LCD.println(DriverStationLCD.Line.kUser4, 15, "Ultrasonic distance: " + b_sonar.getVoltage());
b_LCD.updateLCD();
}

This has been a huge problem for me too this year. I'm using C++ and the code:

DriverStationLCD *m_LCD;

m_LCD->GetInstance();

m_LCD->Printf(DriverStationLCD::kUser_Line1, 1, "Message");

m_LCD->UpdateLCD();

Has no effect. I redeployed our 2011 code to it for the sake of User Message printing but all of the old commands gave no effect as well.
