Finally getting started on my project, The basic sensors I was worried about appear to work, but will need a little tweaking.
However I want to use a nextion display. I have a couple NX3224T024_011 variants here which I am going to use for testing, maybe the final project but not sure as yet.
However they run on 5v (as they all seems to according to their website). While I can feed the display with 5v, but I am concerned that the data line coming back from the display will over volt the teensy 4.0, and damage it.
I have some zenner diodes here that I could use as protection, is this a good idea or will it adversely affect the data signal, is needed at all?
Further to this is the 3.3v from the teensy output enough to send data to the nextion?
I can't help but think that the answer is there somewhere, I have just missed or overlooked it.
