AMS 5915-0100-D Change I2C Address

[Eduardo_Mtz]

Hi @rynej, Checking the data sheet indicates that the I2C address is factory programmed:

The pressure sensors in the AMS 5915 series have a standard, factory-programmed 7-bit slave address of 0x28Hex (0101000b).

And in our web site:

Note that some nodeLynk I2C devices have a fixed address while others allow configuration of the address across a limited range of addresses.

So I don’t think it can be a simple task to reprogram it. I think the most direct solution would be a multiplexer as @TravisE_NCD_Technica mentioned here:

@Travis

It is not possible to mount 2 AMS5915 sensors to the same bus since they have a fixed I2C address as you mentioned. The only way to use 2 AMS5915 sensors would be to use an I2C bus multiplexer like these:

store.ncd.io

TCA9546A 4 Channel SMBUS I2C Multiplixer

tca9546a 4 channel i2c multiplexer with onboard power management, connect multiple i2c sensors with same address works with raspberry pi Arduino USB

Price: USD 19.95

Let us know if you have any other questions.

Thanks,
Eduardo.
