2012-11-04lib: add rtlsdr_get_index_by_serial()Steve Markgraf
This allows to open a device by a name (serial number string) that has been programmed with rtl_eeprom -s. Signed-off-by: Steve Markgraf <steve@steve-m.de>
2012-11-02add library support for EEPROM access and tool for modificationSteve Markgraf
rtl_eeprom can be used to modify the USB descriptor strings etc. Signed-off-by: Steve Markgraf <steve@steve-m.de>

2012-09-13add support for direct sampling modeSteve Markgraf
This commit adds the function rtlsdr_set_direct_sampling() which can be used to enable/disable a mode where the RTL2832 acts as a direct sampling receiver. This mode disables the tuner, and by attaching a long wire, or better, a 50Ω to 200Ω transformer and a lowpass- filter to the In-phase ADC input (pin 1 or 2 of the RTL2832, whereas pin 1 is at the molded dot) it is possible to listen to shortwave radio stations. The coupling capacitors can be left in place, but for better results they should be removed. Tuning in this mode is done with the DDC, and since the ADC samples with 28.8 MHz, tuning is possible from 0 to 28.8 MHz. Signed-off-by: Steve Markgraf <steve@steve-m.de>
2012-09-08add initial support for the R820T tunerSteve Markgraf

2012-08-02return RTLSDR_TUNER_UNKNOWN (0) on failure of rtlsdr_get_tuner_typeDimitri Stolnikov
2012-07-08apply frequency correction value on the xtal clock directlyDimitri Stolnikov
by using this approach both, the tuning frequency and the sample rate should be corrected at the same time.
2012-07-07disable DAGC by default, add control functionSteve Markgraf
This adds rtlsdr_set_agc_mode() to enable/disable it. Thanks to Leif Asbrink for finding this setting. Signed-off-by: Steve Markgraf <steve@steve-m.de>
2012-07-05add api function to control the IF gain for E4000 tunersDimitri Stolnikov
2012-06-02introduce getters for tuner parameters (gain, type)Dimitri Stolnikov
2012-05-20introduce api function to read usb string descriptorsDimitri Stolnikov
This API allows to read manufacturer and product names as well as the serial number advertized by the device on the bus.
2012-05-17add an initial version of rtl_testSteve Markgraf
This tool allows to check for lost samples (and thus check the USB connection), as well as benchmark the Elonics E4000 tunable range. (-t switch) Signed-off-by: Steve Markgraf <steve@steve-m.de>

2012-05-04use new E4000 tuner driver, allow manual gainSteve Markgraf
Many thanks to Hoernchen for making the driver work properly and adding manual gain! Signed-off-by: Steve Markgraf <steve@steve-m.de>
2012-04-25introduce api to configure crystal oscillator frequencyDimitri Stolnikov
Usually both, the RTL and the tuner ICs 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 samplerate) error caused by the original cheap crystal. This commit covers all tuner drivers except of the Fitipower FC2580
2012-04-24return frequency and sample rate as unsigned integersDimitri Stolnikov
2012-04-22rtlsdr_read_async: buffer length must be multiple of 512Dimitri Stolnikov
2012-04-08new api: rtlsdr_read_async function allows to specify buffer sizeDimitri Stolnikov
this commit deprecates rtlsdr_wait_async function various small fixes are included in this commit
