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'll briefly check the GUI.

What's in the GUI
The TDC1000 ultrasonic analog front-end IC has a plethora of attributes that can be set and read. The settings drive the behavior of the IC, and also provide the readings.
The firmware on the MSP430 drives the communication with both the analog sensor chip and with the GUI (via USB)
The GUI has several screens where you can set the parameters for the TDC1000. And it allows you to do one-shot and continuous readings of the sensor values.
As a first trial in this roadtest I've simply tried it out by putting a can with paint on top - without any thought - just because I had it at hand.
The only thing that I want to try out is if the sensor can detect if the canister is present above the sensor or not. That's not really a precision exercise, but it shows that all components are connected, working, and talking to each other.
And it works. I've done a graphing exercise, and also checked if the level meter moved when the can is moved off of the sensor.
I've done nothing scientific here. There's no precision to be found in this exercise. It is comforting though that everything runs out of the box, and that I don't have compatibility issues.
That opens the road for the real experiments...
