Just trying to use both sensors on one Arduino. I could just use two Arduino’s and have one Arduino feeding data into the other but this is cheating.
I may have killed it with the 5v as you mentioned but I don’t remember doing this. I read on other forumz that 0x40 is an address for HID-I2C which is something to do with pins PS0 and PS1. I am thinking that if I haven’t destroyed the chip already maybe there is a way to revert it back to the normal id’s.
