Pervasive Displays Library Suite - Basic edition for EXT4 and EPDK-Matter

The Pervasive Displays Library Suite is specifically designed for the Pervasive Displays e-paper screens, extension boards and evaluation kits.

The library PDLS_EXT4_Basic_Matter turns legacy.

As a replacement, use the PDLS_Basic library, with dedicated examples for the EXT4 and EPDK-Matter.

The PDLS_EXT4_Basic_Matter library supports the screens

• iTC monochrome screens with wide temperature and embedded fast update (film K), up to 2.9";

the boards

• Pervasive Displays EPD Extension Kit Gen 4 (EXT4),
• Pervasive Displays EXT4-to-Nano adapter;

and the kit

• E-Paper Development Kit for Matter (EPDK-Matter), which includes a Pervasive Displays EPD Extension Kit Gen 4 (EXT4) and a Pervasive Displays EXT4-to-Nano adapter boards, a Pervasive Displays 2.9″ 384x168 E-ink monochrome high-definition with embedded fast update and wide temperature display, an Arduino Nano Matter board based on Silicon Labs MGM240S.

The library has also been tested successfully against the Silicon Labs EFR32xG24 Explorer Kit board.

Features
