VCTCXO Trim DAC

Description

These functions provide the ability to manipulate the VCTCXO Trim DAC.

These functions are thread-safe.

Functions
API_EXPORT int CALL_CONV	bladerf_get_vctcxo_trim (struct bladerf *dev, uint16_t *trim)
API_EXPORT int CALL_CONV	bladerf_trim_dac_write (struct bladerf *dev, uint16_t val)
API_EXPORT int CALL_CONV	bladerf_trim_dac_read (struct bladerf *dev, uint16_t *val)

Function Documentation

bladerf_get_vctcxo_trim()

API_EXPORT int CALL_CONV bladerf_get_vctcxo_trim	(	struct bladerf *	dev,
		uint16_t *	trim
	)

Query a device's VCTCXO calibration trim

Parameters

	dev	Device handle
[out]	trim	VCTCXO calibration trim

Returns

0 on success, value from Error codes list on failure

bladerf_trim_dac_read()

API_EXPORT int CALL_CONV bladerf_trim_dac_read	(	struct bladerf *	dev,
		uint16_t *	val
	)

Read value from VCTCXO trim DAC.

This is similar to bladerf_get_vctcxo_trim(), except that it returns the current trim DAC value, as opposed to the calibration value read from flash.

Use this if you are trying to query the value after having previously made calls to bladerf_trim_dac_write().

Parameters

	dev	Device handle
[out]	val	Current VCTCXO trim DAC value

Returns

0 on success, value from Error codes list on failure

bladerf_trim_dac_write()

API_EXPORT int CALL_CONV bladerf_trim_dac_write	(	struct bladerf *	dev,
		uint16_t	val
	)

Write value to VCTCXO trim DAC.

Note

This should not be used when the VCTCXO tamer is enabled.

Parameters

	dev	Device handle
[in]	val	Desired VCTCXO trim DAC value

Returns

0 on success, value from Error codes list on failure
