Hi Franck,

in a similar application (reading out Optomuxes) we use one
calc record per channel that converts from Optomux readout
numbers to temperatures. The slopes and intercepts are
pvLoaded at boot time (but of course can be pvloaded again
any time later as well).

Dear all

We have a question about implementing device support for an ADC that returns values in a waveform record, not using asyn.
If we want the data to be converted from the ADC voltage range into user's engineering data, we need engineering limits or scaling factors or...
Seems that waveform is not as detailed as ai for that.

I guess that we are not the only one in the globe having this issue.
I'll appreciate to have some indication on the implementation.
