When i compile my LCD program it runs but the when I try to restart the robot it will not run and just displays this:

but 0 0 0
but 0 0 0

Here is my code so far:

#pragma config(UART_Usage, UART1, uartVEXLCD, baudRate19200, IOPins, None, None)
#pragma config(UART_Usage, UART2, uartNotUsed, baudRate4800, IOPins, None, None)
//!!Code automatically generated by ‘ROBOTC’ configuration wizard !!//

#pragma platform(VEX)

//Competition Control and Duration Settings
#pragma competitionControl(Competition)
#pragma autonomousDuration(20)
#pragma userControlDuration(120)

#include “Vex_Competition_Includes.c” //Main competition background code…do not modify!

/////////////////////////////////////////////////////////////////////////////////////////
//
// Pre-Autonomous Functions

// You may want to perform some actions before the competition starts. Do them in the
// following function.
//
/////////////////////////////////////////////////////////////////////////////////////////

void pre_auton()

{

bStopTasksBetweenModes = false;
bLCDBacklight=true;
clearLCDLine(0);
clearLCDLine(1);

displayLCDCenteredString(0,“Welcome”);
displayLCDCenteredString(1, “Volt Robotics”);
wait1Msec(5000);
}

Any help would be greatly appreciated!

Everything looks good on the code end; usually when we see this issue, it’s because the LCD screen is plugged into the wrong UART port or the RX/TX wires are plugged into the wrong ports. Double check to make sure that the UART1 port is being used on the Cortex and that the RX/TX cables are plugged into the correct ports (the cable with the orange signal cable should be to the left, the cable with the white signal cable should be to the right, with the VEX logo at the top of the LCD screen).

Let us know if that solves the problem for you.
