Reversed? #63

Closed juzhang74 closed 3 years ago

juzhang74 commented 3 years ago

Hi, in your sourcecode "lib/common/device_handler.cc", there is

506 | if (nco_freq > 0) 507 | cmix_mode = 0; 508 | else if (nco_freq < 0) 509 | cmix_mode = 1;

But with my test, it seems be reversed? Are you sure it's correct in your code?

Yes, with cmix mode = 0 signal is upconverted. https://github.com/myriadrf/LimeSuite/blob/master/src/lime/LimeSuite.h#L681
