Pervasive Displays Library Suite¶
The Pervasive Displays library suite is specifically designed for the Pervasive Displays monochrome and colour iTC panels and the EXT3 extension board.
It provides a high-level interface to drive the e-paper screens with global, fast and partial update, supports capacitive touch and haptic feed-back.
General architecture¶
The suite contains three layers:
-
The application libraries include graphics with clock, gauge and histogram; GUI with label, button, check-box or slider; codes with bar- and QR-codes; file to save and retrieve BMP and serial to generate header files on serial console;
-
The screen libraries support additional screen-specific features for the Pervasive Displays e-paper screens;
-
The shared libraries provide the common classes with basic routines and the interface for the peripherals GPIO, UART, SPI and I²C; along with the fonts libraries.
An appendix contains application notes, reference designs, a glossary, an index, copyright, licence and disclaimer and other documents.
Documentation¶
The documentation consists on two documents:
-
This User guide focuses on how to use the different libraries, with commented examples;
-
The Reference manual lists all the objects and functions, with details for their parameters and returned results.
