Function Documentation

void ezLCD_clear

(

void

)

This function is used to clear the entire screen and fill it with the current color.

Assumptions

• The user has set the current color.
• The user has initialized the MCU's SPI interface with the EZLCD_INIT_SPI() macro.
• The user has set the MCU's SPI pins to inputs and outputs appropriately.
  
  
  • SS_BAR = OUTPUT
  • SCK = OUTPUT
  • MOSI = OUTPUT
  • MISO = INPUT

void ezLCD_fill

(

void

)

This function is used to fill the area surrounding the current position with the current color. It fills every pixel surrounding the current position which shares the same color. It stops when encountering a pixel of a different color. This is similar to the paint bucket tool in Microsoft Paint or other image editing programs.

void ezLCD_fill_bound	(	uint8_t	red,
		uint8_t	green,
		uint8_t	blue
	)

This function is used to fill the area surrounding the current position with the current color. It fills every pixel surrounding the current position until it hits pixels of the specified RGB value.
