GPIO Library

GPIO Library

The XMOS GPIO library allows you to access XMOS ports as low-speed GPIO

Although XMOS ports can be directly accessed via the xC programming language this library allows more flexible usage. In particular, it allows splitting a multi-pin output/input port to be able to the individual pins independently. It also allows accessing ports across separate XMOS tiles or separate XMOS chips.

Features

  • Abstract interface to GPIO functionality of XMOS ports
  • Allow separate access to multibit ports
  • Allow access to ports across tiles

Operating modes

  • Multibit output for individual access to the pins of a multibit output port
  • Multibit input for individual access to the pins of a multibit input port
  • Multibit input for individual access to the pins of a multibit input port allowing the application to react to events on those pins

Software version and dependencies
