Hello,

I wnat to know how we can use the digital pins of the ppk2 I want to send a high signal from my stm32 to ppk2 and than it should start reading the current drawn by my stm32. I am using the ppk2 in source mode. Kindly if someone know please guide.

I am having issue too understanding how to use the digital IN, the first issue, is not clear what is the treshold voltage, the second I connected the Vout to D0, set voltage to 3.3 and looks like nothing is beeing detected.
