Function Documentation

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_indexThe defined EPD size
previous_image_addressThe address of memory that stores previous image
new_image_addressThe address of memory that stores new image
On_EPD_read_flashDeveloper needs to create an external function to read flash

Definition at line 79 of file EPD_controller.cpp.

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_indexThe defined EPD size
previous_image_addressThe address of memory that stores previous image
new_image_addressThe address of memory that stores new image
On_EPD_read_flashDeveloper needs to create an external function to read flash

Definition at line 121 of file EPD_controller.cpp.

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_indexThe defined EPD size
previous_image_ptrThe pointer of memory that stores previous image
new_image_ptrThe pointer of memory that stores new image

Definition at line 53 of file EPD_controller.cpp.

void EPD_display_init ( void   )

Initialize the EPD hardware setting.

Definition at line 39 of file EPD_controller.cpp.

void EPD_power_init ( uint8_t  EPD_type_index )

Initialize the EPD hardware setting and COG driver.

Parameters:
EPD_type_indexThe defined EPD size
