Hi Jonathan,
For the metering parts I think we need to define a few more channel types.
How about this ones
inSX S is the apparent power.
inPX P is the active power.
inQX Q is the reactive power.
inVX V is the voltage. (only inX ?)
inVRMSX VRMS is the quadratic mean voltage.
inIX I is the current.
inIRMSX IRMS is the quadratic mean current.
Since they won't be really popular
How about using a string in iio_chan_type_name_spec
[IIO_IN_GENERIC] = "in%s",
Greetings,
Michael
