This patch makes the following modifications to cx24123.c :
- fixed the reception of channels with low symbol rates.
( The VGA1 and VGA2 offsets recommended by cx24109 docs for
symbol rates from 1 to 5 MSps do not work. I changed them
to values found experimentally. The charge pump current
and FILTUNE voltage are now set to values recommended in
the docs. This improves reception for symbol rates < 15 MSps.
The values written in the SYSSymbolRate registers are calculated
with better precision. )
- fixed the cx24123_get_fec() function. It was returning the values
for DCII mode.
- removed some unused variables
This patch includes the changes I sent earlier, that add support for
I tested the patch on channels with low symbol rates from different
satellites. Now these work fine (from VDR's channels.conf):
