Help¶

Enable the emulated GPIO driver. Mainly used for testing, this driver allows for an arbitrary number of emulated GPIO controllers to be instantiated. Furthermore, the emulated pins can be “wired” using the regular GPIO callback API and the additional API available in drivers/gpio/gpio_emul.h . Configuration for each GPIO instance is accomplished using device tree and an example of such a configuration is in tests/drivers/gpio/gpio_basic_api/boards/native_posix_64.overlay If unsure, say N.
