Detailed Description

Provide access to "LCD" on the Driver Station. This is the Messages box on the DS Operation tab.

Buffer the printed data locally and then send it when UpdateLCD is called.

Constructor & Destructor Documentation

DriverStationLCD::DriverStationLCD ( )

protected

DriverStationLCD contructor.

This is only called once the first time GetInstance() is called

Member Function Documentation

void DriverStationLCD::Clear

(

)

Clear all lines on the LCD.

DriverStationLCD * DriverStationLCD::GetInstance ( )

static

Return a pointer to the singleton DriverStationLCD.

void DriverStationLCD::Printf	(	Line	line,
		int32_t	startingColumn,
		const char *	writeFmt,
			...
	)

Print formatted text to the Driver Station LCD text bufer.

Use UpdateLCD() periodically to actually send the text to the Driver Station.

Parameters

line	The line on the LCD to print to.
startingColumn	The column to start printing to. This is a 1-based number.
writeFmt	The printf format string describing how to print.

void DriverStationLCD::PrintfLine	(	Line	line,
		const char *	writeFmt,
			...
	)

Print formatted text to the Driver Station LCD text bufer. This function pads the line with empty spaces.

Use UpdateLCD() periodically to actually send the text to the Driver Station.

Parameters

line	The line on the LCD to print to.
writeFmt	The printf format string describing how to print.

void DriverStationLCD::UpdateLCD

(

)

Send the text data to the Driver Station.
