Additional tuning status values req'd for tda10048

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The TDA10048 (channel decoder) has some status registers
that are helpful for fast scanning and accurate tuning.

AUTO_OFFSET/OFFSET_F and FREQERR_R/TIMERR_R - for offset detection and tuning &
sampling clock correction

How would features such as these fit into the existing frontend API ?

I could imagine a FE_CAN_OFFSET_AUTO, FE_CAN_FREQ_CORRECT and
FE_CAN_SAMP_CLOCK_CORRECT, in fe_caps,
and an FE_HAS_OFFSET in fe_status, but can't see how you could
read or set any of the other values without extending ioctls.

Regards,
