Configuration GPIO

Description

These functions provide the ability to read and write the configuration GPIO.

These functions are thread-safe.

Functions
API_EXPORT int CALL_CONV	bladerf_config_gpio_read (struct bladerf *dev, uint32_t *val)
API_EXPORT int CALL_CONV	bladerf_config_gpio_write (struct bladerf *dev, uint32_t val)

Function Documentation

bladerf_config_gpio_read()

API_EXPORT int CALL_CONV bladerf_config_gpio_read	(	struct bladerf *	dev,
		uint32_t *	val
	)

Read the configuration GPIO register.

Parameters

	dev	Device handle
[out]	val	Current configuration GPIO value

Returns

0 on success, value from Error codes list on failure

bladerf_config_gpio_write()

API_EXPORT int CALL_CONV bladerf_config_gpio_write	(	struct bladerf *	dev,
		uint32_t	val
	)

Write the configuration GPIO register.

Note

Callers should be sure to perform a read-modify-write sequence to avoid accidentally clearing other GPIO bits that may be set by the library internally.

Parameters

	dev	Device handle
[out]	val	Desired configuration GPIO value

Returns

0 on success, value from Error codes list on failure
