Indeed. I should also announce this status for the md8800...
What's your opinion on this:
According to the hints i got, the isl6405 is visible only on one section
of the md8800. The other section has control over the voltage through
a GPIO port. So unless i do something very dirty, there will either be the
- that the DVB-S decoder of the 16be:0007 section needs to be selected first.
Otherwise the other DVB-S part will not work
- or i will need to always fire up the LNB supply of the 0008 section as soon
as DVB is initialized.
The second approach has the advantage that it has little effect for the end
user while the first needs to be explained.
But i am not sure whether the isl6405 is fully short circuit proof. I will read
the datasheet again...
