◆ send()

virtual void DisplayInterface::send ( uint8_t  data)
pure virtual

Sends byte to display device.

Parameters
data- byte to send

◆ startBlock()

virtual void DisplayInterface::startBlock ( lcduint_t  x,
lcduint_t  y,
lcduint_t  w 
)
pure virtual

Sets block in RAM of lcd display controller to write data to.

Sets block in RAM of lcd display controller to write data to. Width can be specified as 0, thus the library will set the right boundary to region of RAM block to the right column of the display.
