Getting started

The Pervasive Displays library suite comes in four editions: Basic, Evaluation, Commercial and Viewer.

The Used environment page lists the requirements for each edition.

Basic edition

The Basic edition supports normal update for all the screens, fast update for the monochrome screens with embedded fast update and with touch.

It provides all the functions for shapes and text.

It is shared under Creative Commons - Attribution ShareAlike (summmary , legal code ).

It is a set of standard Arduino libraries, and can easily be ported to any other SDK or API by adapting the peripherals library as described in the technical note Migrate to another SDK.

Evaluation edition

The Evaluation edition supports normal update for all the screens, fast update for the monochrome screens with embedded fast update and with touch.

It includes the fixed Mono font and the proportional Serif and Sans Serif fonts; application libraries like graphics, GUI and bar- and QR-code.

It comes as pre-compiled libraries for evaluation only and non-commercial usage.

It is a set of pre-compiled Arduino libraries.

Commercial edition

The Commercial edition adds to the Evaluation edition the use of external SPI SRAM memory for the frame-buffer and external SPI Flash memory for the fonts.

It provides the source code for commercial usage.

It is platform-agnostic: the set of standard Arduino libraries can easily be ported to any other SDK or API by adapting the peripherals library as described in the technical note Migrate to another SDK.

Viewer edition

The Viewer edition runs as a Linux and Windows native application to simulate an e-paper screen and manage touch.

It shares the same fonts and application libraries with the Commercial edition.

It allows to develop the application software independently of the hardware.
