[PATCH 0/3] iio: add unit converter

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

 



Hi!

This moves the iio-mux driver to a new category, since I think
it will be the single driver in that category forever, and now
I'm adding a new driver that is somewhat similar in nature...

But that rename is not very interesting, it's just reshuffling.
It's the new driver that I need. Specifically, I need to allow
linear scaling and modification of the type of an io-channel.
I don't know exactly how that is accomplished in the best way,
but this is what I came up with.

The use cases are an ADC hooked up to measure a "big" voltage by
looking at the midpoint of a voltage divider, and an ADC used
to measure the current by looking at the voltage over a resistor.

Comments?

Cheers,
Peter
