Screen libraries¶
The screen libraries bring the specific routines required by the e-paper screens.
Compared to other screens, the e-paper screens relies on a frame-buffer.
-
The screen object generates the image in the frame-buffer using the text and graphics primitives.
-
The driver object sends the content of the frame-buffer to the screen and refreshes the panel when the command
flush()is called.
The driver and screen libraries come in different versions, based on the screen film and size for the driver, and the edition for the screen, as explained in Select the libraries.
Ancillary libraries share common functions. The board library includes low-level functions for the extension boards hardware and the simulated Viewer. The utilities library shares common functions and variables for all the screens.
Warning
For a safe connection of the e-paper displays, please refer to EPD Handling and ESD Precaution .
