Function Documentation

void EPD_display_partialupdate	(	uint8_t	EPD_type_index,
		long	previous_image_address,
		long	new_image_address,
		long	mark_image_address,
		EPD_read_flash_handler	On_EPD_read_flash
	)

Write image data from Flash memory to the EPD using partial update.

Parameters

EPD_type_index	The defined EPD size
previous_image_address	The previous image address
new_image_address	The new (canvas) image address
mark_image_address	The mark image address
On_EPD_read_flash	Developer needs to create an external function to read flash

partial update uses two stages: black/white and new image

Power off COG Driver

Save image combines with ASCII text

void erase_image	(	long	address,
		uint8_t	EPD_size
	)

To erase the image data.

Parameters

address	The start address to be erased
EPD_size	The EPD size

void read_flash	(	long	flash_address,
		uint8_t *	target_buffer,
		uint8_t	byte_length
	)

Read Flash data into buffer.

Parameters

flash_address	The start address of Flash
target_buffer	The target address of buffer will be read
byte_length	The data length will be read

void write_flash	(	long	flash_address,
		uint8_t *	source_address,
		uint8_t	byte_length
	)

Write Flash data from buffer.

Parameters

flash_address	32 bit flash memory address
source_address	The source address of buffer will be written
byte_length	The data length will be read
