TMP 107 Python Script

Other Parts Discussed in Thread: TMP107

Hello,

I am using a TMP107 and it is connected to a linux computer. I am trying to use Python to read the serial port, but I am not able to see any values over the port. Do I need to initialize the temperature sensor before I can read the values? Also, is there a python script available to read the temperature values?

Thanks

Hi Umadevi,

Unforunately, we do not have Python script for Linux; however, I do have source code in C as well as different method of configuration. Let me know if you are interested.

Normally, all TMP107 default address is always programmed to zero at the factory. Before you can communicate the TMP107, you must issue address command in order for you to execute the individual read command. If you have multiple devices on the daisy-chain, you must assign address and intialize them.

Hope this helps. Let me know if you have further question.

I am interested in both the source code in C and the different method of configuration. Where can I find the individual read command or the initialization command in the manual?

Hi Umadevi,

Please see attached files. In section 7.3.3.2.1.1 in the datasheet, there is some information how to initialize the TMP107.
