Detailed Description

Deprecated C API for GPIO is staying in place for a few versions to support backwards compatibility.

This should not be used for anything new.

Deprecated:

These should only be used for casting to configs, and are planned to be reomved in a future version.

Function Documentation

dsy_gpio_deinit()

void dsy_gpio_deinit

(

const dsy_gpio *

p

)

Deinitializes the gpio pin

Parameters

*p	Pin pointer

dsy_gpio_init()

void dsy_gpio_init

(

const dsy_gpio *

p

)

Initializes the gpio with the settings configured.

Parameters

*p	Pin pointer

dsy_gpio_read()

uint8_t dsy_gpio_read

(

const dsy_gpio *

p

)

Reads the state of the gpio pin

Parameters

*p	Pin pointer

Returns

1 if the pin is HIGH, and 0 if the pin is LOW

dsy_gpio_toggle()

void dsy_gpio_toggle

(

const dsy_gpio *

p

)

Toggles the state of the pin so that it is not at the same state as it was previously.

Parameters

*p	Pin pointer

dsy_gpio_write()

void dsy_gpio_write	(	const dsy_gpio *	p,
		uint8_t	state
	)

Writes the state to the gpio pin Pin will be set to 3v3 when state is 1, and 0V when state is 0

Parameters

*p	Pin pointer
state	State to write
