Constructor & Destructor Documentation

PT6311_VFDEM2	(	PinName	mosi,
		PinName	miso,
		PinName	sclk,
		PinName	cs
	)

Constructor for class for driving Princeton PT6311 VFD controller as used in VFDEM2.

Supports 12 Grids of 16 Segments and Icons (10 digits of 14 Segments plus some icons and another 2 Icon grids). Also supports a scanned keyboard of 7 keys and 1 LED.

Parameters:

PinName mosi, miso, sclk, cs SPI bus pins

Definition at line 296 of file PT6311.cpp.

Member Function Documentation

int _putc ( int value ) [protected, virtual]

Write a single character (Stream implementation)

Definition at line 425 of file PT6311.cpp.

void clrIcon ( Icon icon )

Clr Icon.

Parameters:

Icon	icon Enums Icon has Grid position encoded in 8 MSBs, Icon pattern encoded in 16 LSBs

Returns:: none

Definition at line 392 of file PT6311.cpp.

void cls ( bool clrAll = false )

Clear the screen and locate to 0.

Parameters:

bool	clrAll Clear Icons also (default = false)

Definition at line 344 of file PT6311.cpp.

void cls ( ) [inherited]

Clear the screen and locate to 0.

Definition at line 63 of file PT6311.cpp.

int columns ( )

Number of screen columns.

Parameters:

none

Returns:: columns

Definition at line 336 of file PT6311.cpp.

bool getKeys ( KeyData_t * keydata ) [inherited]

Read keydata block from PT6311.

Parameters:

*keydata Ptr to Array of PT6311_KEY_MEM (=6) bytes for keydata

Returns:: bool keypress True when at least one key was pressed

Note: Due to the hardware configuration the PT6311 key matrix scanner will detect multiple keys pressed at same time, but this may result in some spurious keys also being set in keypress data array. It may be best to ignore all keys in those situations. That option is implemented in this method depending on define setting.

Parameters:

*keydata Ptr to Array of PT6311_KEY_MEM (=6) bytes for keydata

Returns:: bool keypress True when at least one key was pressed

Note: Due to the hardware configuration the PT6311 key matrix scanner will detect multiple keys pressed at same time, but this may also result in some spurious keys being set in keypress data array. It may be best to ignore all keys in those situations. That option is implemented in this method depending on define setting.

Definition at line 156 of file PT6311.cpp.

char getSwitches ( ) [inherited]

Read switches from PT6311.

Parameters:

none

Returns:: char for switch data (4 least significant bits)

Definition at line 202 of file PT6311.cpp.

void locate ( int column )

Locate cursor to a screen column.

Parameters:

column The horizontal position from the left, indexed from 0

Definition at line 322 of file PT6311.cpp.

int printf	(	const char *	format,
			...
	)

Write a formatted string to the Display.

Parameters:

int putc ( int c )

Write a character to the Display.

Parameters:

c	The character to write to the display

void setBrightness ( char brightness = PT6311_BRT_DEF ) [inherited]

Set Brightness.

Parameters:

char	brightness (3 significant bits, valid range 0..7 (1/16 .. 14/16 dutycycle)

Returns:: none

Parameters:

char	brightness (3 significant bits, valid range 0..7 (1/16 .. 14/14 dutycycle)

Returns:: none

Definition at line 83 of file PT6311.cpp.

void setDisplay ( bool on ) [inherited]

Set the Display mode On/off.

Parameters:

bool	display mode

Definition at line 95 of file PT6311.cpp.

void setIcon ( Icon icon )

Set Icon.

Parameters:

Icon	icon Enums Icon has Grid position encoded in 8 MSBs, Icon pattern encoded in 16 LSBs

Returns:: none

Definition at line 373 of file PT6311.cpp.

void setLED ( char leds = 0 ) [inherited]

Set LEDs.

Parameters:

char	leds (5 least significant bits)

Returns:: none

Definition at line 229 of file PT6311.cpp.

void setUDC	(	unsigned char	udc_idx,
		int	udc_data
	)

Set User Defined Characters (UDC)

Parameters:

unsigned	char udc_idx The Index of the UDC (0..7)
int	udc_data The bitpattern for the UDC (16 bits)

Definition at line 412 of file PT6311.cpp.
