Dynamic change of reference voltage for monitoring two signals (PSOC4)
I am new to PSOC so please bear with me if this question seems very simple :) I am looking for measuring a signal and battery voltage (for battery monitoring) at the same time. For battery monitoring the reference voltage is fixed but for the signal I should be able to change the reference voltage at run time. Is that possible? Also, for the signal voltage I need to use a comparator so that minimum code is written and all is done by hardware is meausre number of pulses. I found one example that for that as attached but note sure how -ve of LPComp_1 is driven here by SAR. Could anybody please help?
Thank a lot,
