lib: enable standby mode of e4k and r820t on exit

2013-01-16T00:43:45Z

Since the R820T is a power hog and gets quite hot, this makes sense, especially when being battery- powered. Signed-off-by: Steve Markgraf

lib: add rtlsdr_get_index_by_serial()

2012-11-04T12:57:56Z

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

add library support for EEPROM access and tool for modification

2012-11-02T20:47:14Z

rtl_eeprom can be used to modify the USB descriptor strings etc. Signed-off-by: Steve Markgraf

tuner_r820t: improve tuning accuracy, allow freq correction

2012-10-07T00:32:14Z

We now use Hz instead of KHz for calculating the PLL parameters, and use the actual crystal frequency in Hz, which allows to correct the frequency error in ppm. Signed-off-by: Steve Markgraf

add support for direct sampling mode

2012-09-13T19:53:51Z

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
