I’ve got a problem with an electronics project that I’m trying to solve. I’m hoping one of you can give me some guidance.
I am trying to get one circuit board to pass a signal to a second circuit board. The 2nd board has a trigger pin for digital signals that is set up to accept 3.3v/5v trigger either as an edge signal or a level signal. The first board is signalling an event by changing a pin’s voltage from 2.46V to 4.72V.
Any idea how I can connect the 1st to the 2nd? I’m assuming I have to somehow change the 4.72V to 5V for this to work. Does the fact it only goes down to 2.46V, rather than 0V, in non-signal mode an issue?
Thanx in advance. Bill
