liquidsdr.org AGC function documentation incorrect #142

Open twitchyliquid64 opened 6 years ago

twitchyliquid64 commented 6 years ago

Sorry if this is the wrong spot.

The docs here mention:

agc_crcf_set_gain_limits(q,gmin,gmax) sets the minimum and maximum gain values, respectively. This effectively specifies e0 and e1 as in [fig-agc-transfer-function] .

This function does not exist:

# github.com/twitchyliquid64/go-liquiddsp
./agc.go:19:2: could not determine kind of name for C.agc_crcf_set_gain_limits

FAIL    github.com/twitchyliquid64/go-liquiddsp [build failed]

Couldnt find a report link on the site for this, so thought I would open a bug here.

Ah, good catch. Reporting here is fine. You can also email me directly using joseph at liquid sdr dot org.

Hello Joseph,

just stumbled on the same problem here. Needed to limit the maximum gain of the AGC but did not find in the documentation https://liquidsdr.org/doc/agc/ mentioned interface agc_crcf_set_gain_limits().

Also, I wanted to play around with agc_crcf_squelch_enable_auto() but also did not find it in the interface. But I do not really need that.

As you describe the caption auto-squelch in such in detail I would expect the code will somehow exists for agc_crcf_squelch_enable_auto() or maybe also agc_crcf_set_gain_limits(). Maybe I could find it on a side-branch?
