gnss-sdr/firmware/GN3S_v2/include/usrp_common.h
Javier Arribas b849b20a8c Added optional support for Sparkfun SiGe GN3S USB GPS RF sampler:
- Added a pre-compiled custom GN3S firmware.
- Added a fully-compliant GNU Radio source block for GN3S USB dongle. It can be used also from GNU Radio companion and from Python applications.
- Added a new GN3S_Signal_Source block. It is possible to disable the GN3S signal source compilation. See README.

*
* - between a write to any register in the 0xE600 - 0xE6FF range

* - between a write to one of the registers listed below and a read
