multiple FDC1004 on I²C with an arduino

Benjamin Paffhausen

Other Parts Discussed in Thread: FDC1004, FDC2214

I use the FDC1004 successfully with an arduino, but I need to use 3 of those chips on one arduino, science I need 12 Inputs. It looks like the FDCs adress is not configurable. Is it possible to have multipe FDCs on one I²C ?

thanks Ben

Hi Ben,

For FDC1004, you can only have one device per I2C. For FDC2214, the I2C address is configurable and you can connect two of them to the same I2C.

Hi, Ben

Recently I studied an arduino with FDC1004, but I could not use FDC. So can I get a source code of FDC1004?

Yeah, I would like to have the source code as well! Thanks so much!. BTW there is a way to switch between the chips even though they have the same address. I read that in another question in this forum.
