Detailed Description

Function Documentation

void rflpc_gpio_set_pin_mode_input	(	rflpc_pin_t	pin,
		rflpc_pin_mode_t	mode
	)

Sets a pin to input mode.

Note

This automatically calls rflpc_gpio_use_pin

void rflpc_gpio_set_pin_mode_output	(	rflpc_pin_t	pin,
		uint8_t	val
	)

Sets a pin to output mode Uses a pin as output pin and sets its value.

Note

This automatically calls rflpc_gpio_use_pin with a pull-up configuration

Parameters

pin	pin to use
val	value to set on pin

void rflpc_gpio_use_pin	(	rflpc_pin_t	pin,
		rflpc_pin_mode_t	mode
	)

Configures the multi-purpose pins of the CM3 so that it uses a given GPIO pin.

Parameters

pin	the pin to activate
mode	the mode to set for the pin (pull-up, pull-down,...) see rflpc_pin_mode_t
