How to make DIY I2C slave devices with ease - ATtiny Device

Hi there,
So not being a smart a$$ but none of this carries over to Seeed Xiao specifically, unless there is a Xiao Tiny LOL
?

i didnt put it in xiao… i was investigating making non IIC sensors IIC… also how to change IIC device numbers

Ah’ I see,
You know some devices that are I2C can be switched by asserting the signals and then writing the Address you want it to answer to, YMMV. mostly newer devices , display’s and some Sensors work like that as well. No jumpers or solder bridges. its in a tiny flash bit set onboard.
just fyi. for slaves only btw.
HTH

it should be that way… the IIC address should be held in a read/write regester and you should be able to call the “standard address” and re-write the address regester then reboot

Hi there,
Yep , actually the way was to just remove power (gpio) pin and you golden, device responds to new addy.
It’s dynamic I2C configuration I believe it’s called.on a E-ink display and an O2 sensor made by a cornadian co. if i recall.
