TMP007EVM: How to read other TMP007 temp sensor on the I2C bus using the Eval software

user3727916

Part Number: TMP007EVM

I've been trying to read the temperature from another sensor on the same I2C bus (using another address) but it seems that the EVM software has a build in address to read from a sensor, which is 0x00. Is it possible to read data from a sensor on the same bus that has an address other than 0x00?

Thanks

TMP007EVM GUI is hard-coded to communicate with a TMP007 device at the I2C bus address 0x40. See Table 4 Serial Bus Address on page 18 of the TMP007 datasheet. This address can't be changed in the GUI software.

Hi
the question is -
if using a different than TMP007EVM GUI software, then - can other than adress '00' be read/write to ?
Thanks

I'm not sure I understand the problem you're trying to solve. Are you having issues with your TMP007EVM? I2C Address 0 is reserved by the bus specification for general call commands.
