The TDC1000-TDC7200EVMTDC1000-TDC7200EVM evaluation module has 4 main parts The TDC1000 analog front-end and a pre-programmed MSP430 microcontroller on the board, a 1MHz Piezo Ceramic sensor that plugs into the board and a GUI client for on your PC.
In this blog I perform the first measurements.

Test Setup
I've filled the container with water, up to somewhere between 4 and 5 cm. I've used the simplest setup with the sensor mounted under the liquid.
The Piezo sensor is AC, so the color of the wires doesn't really matter. This is how I connected the sensor (all the lower pins are ground).
The speed of sound is configured at 1480 m/s - the default setting of the test software (I've attached a register file that can be imported into the GUI to this blog).
I'm rather satisfied with the first results:
My First Issue
I have a problem when I generate a configuration file in Webench and load that into the gui.
I've logged a post for that on TI's e2e forum.
Edit January 7, 2016: The TI application team has looked at my request and confirmed my findings. Visit this link for a temporary solution.
A full solution to make the Webench config app and the evaluation board's GUI is being worked on.
