commit 0557bbbc438790c4710a5c85970d10e5ba41ef0d Author: Andreas Eversberg jolly@eversberg.eu Date: Wed May 17 19:59:28 2017 +0200

SDR: Checking given parameters with a tollerance of up to 0.001

Rounding errors may cause given parameters to be changed a little. When comparing the set-values with the get-value, a small amount of tollerance must be allowed.

Thanx to Syvain, pointing to this bug!

http://cgit.osmocom.org/osmocom-analog/commit/?id=683078a7a01903c9bcbac19614...

SDR: Spectrum display will not scale FFT result

Instead the greatest possible width that will fit into the window will be used. This width is 2 to the power of N.

http://cgit.osmocom.org/osmocom-analog/commit/?id=ef7ff26793b290d5ee3725a549...

C-Netz: SDR now uses zero-crossing to detect level changes.

This does not work with analog radio, but with SDR it works. The quality should be better and the process is faster.

SDR: Allow direct IQ TX and RX instead of fm modulating a list of channels

This is performed by reading and writing IQ data to "sample" pointer with channel number set to 0.

http://cgit.osmocom.org/osmocom-analog/commit/?id=65694f3b809c3ada5d5a273d0d...

This way it is possible to use SDR simplex

main_common: Move init and cleanup function to main function

http://cgit.osmocom.org/osmocom-analog/commit/?id=4201717f36f1236fd0de159767...

commit 4201717f36f1236fd0de1597679f5e9411c8a7eb Author: Andreas Eversberg jolly@eversberg.eu Date: Sat Mar 4 06:35:38 2017 +0100

Rework on audio buffer management

Use function to get samples to be sent to fill audio buffers to a level. This replaces the function that only shows how much data is in the buffer.

This way the function itself can control how much data will be sent.

http://cgit.osmocom.org/osmocom-analog/commit/?id=9d0e6b82b7cc289fb76e580946...

commit 9d0e6b82b7cc289fb76e580946c8fefcb2b9cb18 Author: Andreas Eversberg jolly@eversberg.eu Date: Sat Mar 4 06:34:04 2017 +0100

Work on docs

Start streaming of sound/SDR just before main loop

This prevents buffer overflow during init/creation processes

http://cgit.osmocom.org/osmocom-analog/commit/?id=04fd1ddceab83bc4480de06992...

commit 04fd1ddceab83bc4480de06992465f28668bcf2c Author: Andreas Eversberg jolly@eversberg.eu Date: Sat Feb 25 06:29:09 2017 +0100
