Constructor & Destructor Documentation

PT6315 ( PinName  mosi,
PinName  miso,
PinName  sclk,
PinName  cs,
Mode  mode = Grid12_Seg16 
)

Constructor for class for driving Princeton PT6315 VFD controller.

Supports 4 Grids of 24 Segments upto 12 Grids of 16 Segments. Also supports a scanned keyboard of upto 32 keys and 4 LEDs. SPI bus interface device.

Parameters:
PinNamemosi, miso, sclk, cs SPI bus pins
Modeselects either number of Grids and Segments (default 12 Grids, 16 Segments)

Supports 4 Grids of 24 Segments upto 12 Grids of 16 Segments. Also supports a scanned keyboard of upto 32 keys and 4 LEDs. SPI bus interface device.

Parameters:
PinNamemosi, miso, sclk, cs SPI bus pins
Modeselects either number of Digits and Segments

Member Function Documentation

void cls (  )

Clear the screen and locate to 0.

Definition at line 63 of file PT6315.cpp.

bool getKeys ( KeyData_t *  keydata )

Read keydata block from PT6315.

Parameters:
*keydataPtr to Array of PT6315_KEY_MEM (=4) bytes for keydata
Returns:
bool keypress True when at least one key was pressed

Note: Due to the hardware configuration the PT6315 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:
*keydataPtr to Array of PT6315_KEY_MEM (=4) bytes for keydata
Returns:
bool keypress True when at least one key was pressed

Returns:
none

Reimplemented in PT6315_DVDR3510.

Definition at line 129 of file PT6315.cpp.
