Member Function Documentation

void cls (  )

Clear the screen and locate to 0.

Definition at line 63 of file PT6318.cpp.

bool getKeys ( KeyData_t *  keydata )

Read keydata block from PT6318.

Parameters:
*keydataPtr to Array of PT6318_KEY_MEM (=6) bytes for keydata
Returns:
bool keypress True when at least one key was pressed

Note: Due to the hardware configuration the PT6318 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 PT6318_KEY_MEM (=6) bytes for keydata
Returns:
bool keypress True when at least one key was pressed
