keywords:	GPIO, ports
devices:	xcore-200, xcore.ai

Summary

lib_gpio provides access to xcore ports as low-speed GPIO.

While xcore ports can be accessed directly using the xC programming language, this library offers more flexibility. In particular, it supports splitting a multi-pin input/output port so that the individual pins can be used independently. It also enables accessing ports across separate xcore tiles or even across different xcore devices.

Features

• Abstract interface to GPIO functionality of xcore ports
• Allow control of individual bits of multi-bit ports
• Allow access to ports across tiles
