What about signal strength and BER readout in parallel for each device
listed here?
Needs the same docs and would not add too much work..
----
tda10021: MSE[7..0] (= reg 0x18 )
"Mean Square Error of the demodulated output signal. MSE can be used as a
representation of the signal quality."
u8 quality = ~tda10021_readreg(state, 0x18);
*snr = (quality << 8) | quality;
ves1820: the same.
tda10023: seems to be the same. (no info, but chip is very close to
tda10021)
