void EPD_display_from_flash	(	uint8_t	EPD_type_index,
		long	previous_image_address,
		long	new_image_address,
		EPD_read_flash_handler	On_EPD_read_flash
	)

Show image from Flash memory.

Parameters

EPD_type_index	The defined EPD size
previous_image_address	The address of memory that stores previous image
new_image_address	The address of memory that stores new image
On_EPD_read_flash	Developer needs to create an external function to read flash

void EPD_display_from_flash_Ex	(	uint8_t	EPD_type_index,
		long	previous_image_address,
		long	new_image_address,
		EPD_read_flash_handler	On_EPD_read_flash
	)

Show image from Flash memory when SPI is common used with COG and Flash.

Note

• This function must work with EPD_power_init when SPI is common used with COG and Flash, or the charge pump doesn't work correctly.
• EPD_power_init -> write data to flash (switch SPI) -> EPD_display_from_flash_Ex

Parameters

EPD_type_index	The defined EPD size
previous_image_address	The address of memory that stores previous image
new_image_address	The address of memory that stores new image
On_EPD_read_flash	Developer needs to create an external function to read flash

void EPD_display_from_pointer	(	uint8_t	EPD_type_index,
		uint8_t *	previous_image_ptr,
		uint8_t *	new_image_ptr
	)

Show image from the pointer of memory array.

Parameters

EPD_type_index	The defined EPD size
previous_image_ptr	The pointer of memory that stores previous image
new_image_ptr	The pointer of memory that stores new image
