Hi I'm looking to connect two MPL3115A2 sensors to my I2C port and was wondering if anyone had any idea how I could do this, if it was possible? The Sensor has an address that is standard and it seems that it can't be changed. What would you suggest I do?
Hi, welcome to the forum.
Manufacturer’s page : http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPL3115A2
Adafruit sells it : http://www.adafruit.com/products/1893
They are made with I2C address 0x60.
But as with many facturers, if you buy many thousands, they can set a different address in it for you.
You could use a special chip that has 2 or 4 multiplexed I2C busses.
Or build a mux yourself and switch the SDA.
I’ll update this since it was near the top on google for my search terms
I have done this using a 4066 and for following circuit and code.
