Is this the ep9302 onboard ADC? If not, ignore me.
my manual says it can do 925 samples per second and needs 2 milliseconds
settling time between channel switches.

what is the question?

sure, theoretically.

don't forget to poll the SDR bit of the ADCResult register. When it is
set a new reading is ready. It is cleared when the result is read.
