some have any idea how i connect this chip to arduino .
Solder, croc clips, pogo pins, bench clamp . . .
I only see 2 pads, are there more? Most anything connected to I2C will need 4 - SCL, SDA, Power, Gnd. Get a small solder iron and attach some leads once the other pins are located.
You sure that's an I2C device, not some weirdo single-wire protocol? What is it? Datasheet?
i am not sure. its a tuner chip . mebay its not i2c?
Feel free to be forthcoming with details. FM tuner? Piano tuner? Details could also include better pictures.
So that’s a 1-wire protocol device, if those are the only pads - my betting is it’s the security chip (which I assume is why you want to fiddle with it). Research that model online and see if anyone has figured out how to interface with it - it may be challenging due to it’s being designed to prevent tampering.
are you sure that 1-wire protocol device?
Have you got any better ideas?
