2006-10-29 | lgdt330x: SNR and signal strength reporting | Michael Krufky | |
From: Trent Piepho <xyzzy@speakeasy.org> Update the SNR calculations to use the new dvb_math log function, and add SNR calculations for all supported modulations for both lg dt3302 and dt3303. The QAM equations don't appear in the dt3302 datasheet, so the ones from the dt3303 datasheet were used. SNR returned is the actual value in dB as 8.8 fixed point. Reporting of real signal strength isn't supported, so rather than return 0, which confuses some software and users, a re-scaled SNR value is returned. Code originally by Rusty Scott.

2005-07-25 | Rename lgdt3302 to lgdt330x, to make way for the addition of lgdt3303 support. | Michael Krufky | |
This imports exact copies of the following versions from dvb-kernel cvs. lgdt3302.c r1.12 lgdt3302.h r1.5 lgdt3302_priv.h r1.3 There will be no more development on lgdt3302. All new development will be on lgdt330x. It will be safe to remove lgdt3302 from cvs once lgdt330x gets merged into -linus kernel tree. Signed-off-by: Michael Krufky <mkrufky@m1k.net> |
