}Methods
impl Device[src]
fn close(&self) -> Error
Close the device.
fn set_xtal_freq(&self, rtl_freq_hz: i32, tuner_freq_hz: i32) -> Error
Sets the crystal oscillator frequencies.
Typically both ICs (rtlsdr and tuner) use the same clock. Changing the clock may make sense if you are applying an external clock to the tuner or to compensate the frequency (and sample rate) error caused by the original (cheap) crystal.
Note, call this function only if you fully understand the implications.
fn get_xtal_freq(&self) -> (i32, i32, Error)
Returns the crystal oscillator frequencies. Typically both ICs (rtlsdr and tuner) use the same clock.
fn get_usb_strings(&self) -> (String, String, String, Error)
Returns the device information (manufact, product, serial). Note, strings may be empty.
fn write_eeprom(&self, data: Vec<u8>, offset: u8) -> Error
Writes information data to the EEPROM.
fn read_eeprom(&self, offset: u8, len: u16) -> (Vec<u8>, Error)
Returns information data read from the EEPROM.
fn set_center_freq(&self, freq_hz: i32) -> Error
Sets the center frequency.
fn get_center_freq(&self) -> i32
Returns the tuned frequency or zero on error.
fn set_freq_correction(&self, ppm: i32) -> Error
Sets the frequency correction.
fn get_freq_correction(&self) -> i32
Returns the frequency correction value.
fn get_tuner_type(&self) -> String
Returns the tuner type.
fn get_tuner_gains(&self) -> (Vec<i32>, Error)
Returns a list of supported tuner gains. Values are in tenths of dB, e.g. 115 means 11.5 dB.
fn set_tuner_gain(&self, gain: i32) -> Error
Sets the tuner gain. Note, manual gain mode must be enabled for this to work. Valid gain values may be queried using get_tuner_gains.
Valid values (in tenths of a dB) are: -10, 15, 40, 65, 90, 115, 140, 165, 190, 215, 240, 290, 340, 420, 430, 450, 470, 490
Gain values are in tenths of dB, e.g. 115 means 11.5 dB.
fn get_tuner_gain(&self) -> i32
Returns the tuner gain.
Gain values are in tenths of dB, e.g. 115 means 11.5 dB.
fn set_tuner_bandwidth(&self, bw_hz: i32) -> Error
Sets the device bandwidth.
fn set_tuner_if_gain(&self, stage: i32, gains_tenths_db: i32) -> Error
Sets the intermediate frequency gain.
Intermediate frequency gain stage number 1 to 6. Gain values are in tenths of dB, e.g. -30 means -3.0 dB.
fn set_tuner_gain_mode(&self, manual_mode: bool) -> Error
Sets the gain mode, automatic or manual. Manual gain mode must be enabled for the gain setter function to work.
fn set_sample_rate(&self, rate_hz: i32) -> Error
Sets the sample rate.
When applicable, the baseband filters are also selected based on the requested sample rate.
fn get_sample_rate(&self) -> i32
Returns the sample rate.
fn set_testmode(&self, test_mode: bool) -> Error
Sets device to test mode.
Test mode returns 8 bit counters instead of samples. Note, the counter is generated inside the device.
fn set_agc_mode(&self, agc_mode: bool) -> Error
Sets the AGC mode.
fn set_direct_sampling(&self, mode: SamplingMode) -> Error
Sets the direct sampling mode.
When enabled, the IF mode of the device is activated, and set_center_freq() will control the IF-frequency of the DDC, which can be used to tune from 0 to 28.8 MHz (xtal frequency of the device).
fn get_direct_sampling(&self) -> SamplingMode
Returns the state of direct sampling mode.
fn set_offset_tuning(&self, enable: bool) -> Error
Sets the offset tuning mode for zero-IF tuners, which avoids problems caused by the DC offset of the ADCs and 1/f noise.
fn get_offset_tuning(&self) -> Error
Returns the offset tuning mode.
fn reset_buffer(&self) -> Error
Resets the streaming buffer.
fn read_sync(&self, len: i32) -> (Vec<u8>, i32, Error)
Performs a synchronous read of samples and returns the number of samples read.
fn read_async(&self, f: ReadAsyncCbT, ctx: *mut c_void, buf_num: i32, buf_len: i32) -> Error
Reads samples asynchronously. Note, this function will block until canceled using cancel_async. ReadAsyncCbT is a package global variable.
Optional buf_num buffer count, buf_num * buf_len = overall buffer size, set to 0 for default buffer count of 32.
Optional buf_len buffer length, must be multiple of 512, set to 0 for default buffer length of 262,144 (16 * 32 * 512).
fn cancel_async(&self) -> Error
Cancels all pending asynchronous operations.
fn get_hw_info(&self) -> (HwInfo, Error)
Gets the dongle's information items.
fn set_hw_info(&self, info: &HwInfo) -> Error
SetCenterFreq the dongle's information items.
