Display controller library

Display controller library

The XMOS display controller library provides the service of removing the real-time constraint of maintaining the LCDs line buffer from the application and provides a managed frame buffering service. It does this by using an SDRAM as a storage for the frame buffers.

Features

  • Asynchronous non-blocking interface for modifying frame buffers,
  • User configurable number of frame buffers.

Components

  • Display controller
