I have a quick question about setting the address for the TCA9548A. I'm new to Arduino so I think it's probably easy to answer, but I couldn't find anything specific enough on the web.
I have two TCA9548A multiplexers and they both come with 0x70 (or 1110000) as their default address, and I've am trying to change one of them using the A0 - A2 pins.
I got it to work, but it doesn't seem to save the address... as soon as I remove the signal it switches back to the old address. So I'm wondering if there's a way to make it stick or if I have to constantly send a HIGH signal to it in order to change the address?
