Connect 1.024 Reference to AMUX.
I am sending the V_REF(1.024V) out through an analog pin buffered by an Opamp.
I am also measuring the output of the Opamp by the ADC_DelSig.
This works fine. But now I want to bypass the opamp to measure the V_REF directly. This is done because I want to know the Offset and Gain of the Opamp to do an error correction!
I want to do this on Run-Time because of temperature drift! Therefore I need an AMUX to switch between Opamp yes or not!
Is it possible to route PSoC's internal reference (1.024V) to AMUX?
There is always this error:
Voltage Reference Warning: Vref '' is connected to terminal 'AinTerm1' of 'AMux_1' but no direct hardware connection exists.
