TMP116EVM: How to program TMP116EVM to store temperature data in a file?

Part Number: TMP116EVM
Other Parts Discussed in Thread: TMP117

Hello,

I would like to connect TMP116EVM to an external power source (specifically to RF energy harvesting system).

As such, when the board is powered, I would like to store the temperature data on a file, and then later, disconnect the board, and read the data on a computer.

Any ideas on how I can do that?

Thank you.

Dear Kristi -

these designs were created with about the same intent as I think you have and they should give you some ideas. Here the point I am attempting to share with you is that the FRAM MCU can be partitioned and then leveraged for the logging, in the event you don't want to add an extra memory IC (i.e. SPI flash)

https://www.ti.com/tool/TIDA-00524 (this design has CR2032 battery which keeps system powered for continuous logging into FRAM, then is powered via NFC when handset is present)

https://www.ti.com/tool/TIDA-00230 (this design only logs when powered, in this case via magnetic field, via handset NFC)

https://www.ti.com/tool/TIDA-00217 (similar to one above)
