i want to change APDS 9960 's i2c address
i was tired to finding that
Why would you want to change the address? Or do you want to know the APDS's I2C address?
Look for I2C Scanner Arduino. There is a small sketch that discovers the addresses of I2C devices. I posted it somewhere in the forum (not my sketch!).
The I2C address for Sparkfun module is said: 0x39.
A quick Google search and searching the datasheet of this chip gave me the answer, it's given on page 8:
The device supports a single slave address of 0×39 Hex using 7-bit addressing protocol. (Contact factory for other addressing options.)
So no, you can not change the address.
