The software includes the drivers and the Pervasive Displays Library Suite - Basic edition.

They are specifically designed for the Pervasive Displays e-paper screens, extension boards and development kits.

Drivers

The driver library manages the panel and the board. It sends the content of a C-array image to the screen and refreshes the panel. It is based on the film and the size of the screen.

The drivers are available at the Pervasive Displays GitHub page.

Pervasive Displays Library Suite - Basic edition

The Pervasive Displays Library Suite provides the text and graphics functions and the fonts to generate the image to be displayed through the driver.

Screen_EPD, derived from
hV_Screen_Buffer
