Andreas Eversberg fee4846c3f SDR forces default settings: emphasis and FSK polarity 2017-02-18 21:00:52 +01:00
Andreas Eversberg 8b9277615d Neu structure for the paging process (B-Netz) 
Paging tones are not created within sound_alsa.c
The audio API is now responsible to switch to paging channel.
In case of SDR, the sdr.c will switch frequency offset.

Andreas Eversberg 9ff8c3bb25 Rework on audio interface 
Sound instance is now called audio instance and uses funcation pointers.
This gives a clean interface to be exchanged with other technologies,
linke SDR.

Andreas Eversberg e029a6a858 C-Netz: Generator and Arduino programmer for SIM cards 
It supports the simple memory cards only. Works only with very early
phones, like BSA51 (tested so far).

An SLE4428 card must be written. The card must not have any protected
serial number area. Also the card must read all 416 written bits via ATR,
not only the first 32 bits.
