Difference Between Power Saving Sleep Modes

[rickkas7]

I wrote up a little tutorial that goes into a little more depth about the sleep modes; hopefully that will help.

I'm not sure why you're getting so much current draw in deep sleep mode. My USB power meter reads 0, but that really only means somewhat less than 10 mA, but I'm definitely not seeing > 60 mA.

Sleep mode explained using code samples

There was a recently a question about sleep mode on the Photon, and it wasn’t anything I ever played with, so I made a little circuit and 4 test sketches to play around with it and see how things work, since I was still a little confused after reading the documentation. Each example has the code with a lot of comments followed by an annotated example output, so you can probably figure it out just by reading the examples even if you don’t run the code yourself. Here’s the circuit: [image] The…
