GPIO level handler

Driver to use GPIOTE port event to detect whenever any of multiple GPIO pins are at a specified polarity. This module can be used to wake the nRF SoC from the SYSTEM OFF mode and consumes about 1 uA of current. More...

Data Structures
struct	gpio_level_cfg
	The configuration parameter for each of the GPIO pin that is being configured in the GPIO level handler module. More...

Functions
void	gpio_level_init (gpio_level_cfg *cfg, uint32_t cfg_num, uint32_t irq_priority)
	Initializes the GPIO level handler module by taking in the the configurations of all the GPIOs that need to be monitored. More...

Detailed Description

Function Documentation

gpio_level_init()

void gpio_level_init	(	gpio_level_cfg *	cfg,
		uint32_t	cfg_num,
		uint32_t	irq_priority
	)

Parameters

cfg	A pointer to an array of GPIO configurations which need to be configured to generate port events and call the appropriate handler
cfg_num	The size of the array
irq_priority	The priority of the GPIOTE port event IRQ handler

TODO revert the GPIO configs of the previously configured pins
