Functions
void	gpio_set_value_noninline (gpio_pin_t pin, bool value)

PORT Pin Numbering
For internal use only. These macros are used to generate GPIO pin numbers for each port with the CREATE_GPIO_PIN macro. Each port has 8 pins so e.g. the first pin on PORTB gets number 8, first pin on PORTC gets 16 ...

Detailed Description

For internal use only.

bool gpio_get_value_noninline ( gpio_pin_t pin )

Read the current state of a GPIO pin (non-constant pin version).

Parameters:

pin

A number identifying the pin to read.

Return values:

	true	The pin is currently high (close to Vdd)
	false	The pin is currently low (close to Vss)

void gpio_set_value_noninline	(	gpio_pin_t	pin,
		bool	value
	)

Drive a GPIO pin to a given state (non-constant pin version).

This function will only have an effect if pin is configured as an output.

Parameters:

	pin	A number identifying the pin to act on.
	value	The desired state of the pin. true means drive the pin high (towards Vdd), while false means drive the pin low (towards Vss).
