I need a suggestion from LCNC developers point of view.
I like to read ADC values, transform that values into Temperature values and
make that values available on a hal pin.
ADC values I get from a user-space file inside the device tree.
Since there is a lot of Thermometers who can be connected to the ADC and most
of them are not linear, I need a Look Up Table (LUT) provided by the integrator
who's setting up LCNC.
Idea is, providing the LUT in a .csv file in config directory.
I know, there are several way's, like python script, external c programm, .comp
to do that.
I like to write a component using the comp compiler, (also to get familiar with
it)
Now the question: Is there any draw back doing that using a component?
I ask, because
1. I'm not totally clear right now about the LCNC internals but try to
understand it.
2. I didn't see a component in the source code that uses user space file-I/O.
My idea is:
-Create a component that can have several instances (one for each ADC channel
for example)
-on loading the component parameters are channel number and a LUTxx.csv for
each instance
-each instance read it's LUT at load-time once and keeps it in memory
-conversion and output happens on a signal on an update pin.
I'm open for pros and contras.
