Control noise source from C++

1

If I wanted to rewrite the Heimdall DAQ Firmware and perform my own phase synchronisation between the channels, how would I go about triggering the noise source on and off?

I found the following line in rtl_dac.c;

rtlsdr_set_bias_tee_gpio(rtl_rec->dev, 0, 1);

Does this control the noise source? Otherwise would it be possible to explain the primitive to control this?

Cheers!

Correct, we are just flipping a GPIO on and off to activate/deactivate the noise source.
