1Introduction
The GP30-DEV-KIT is a platform for a quick and easy start-up and evaluation of the TDC-GP30
ultrasonic flow converter (UFC). It supports the QFN32 package, which offers the functionality need
for standard water and heat meters. The development kit offers user-friendly configuration and
extensive testing of the TDC-GP30, but also the complete assembler environment for programming
the device. For a proper use of the evaluation system, we strongly recommend referring to the latest
TDC-GP30 datasheets. The kit includes three elements:
GP30-DEMO-US / GP30-DEMO-US-F01 reference board,
based on TDC-GP30YD (-F01) in QFN32 package
PicoProg Lite with USB-C –USB cable

Please download the software for the kit from https://downloads.sciosense.com/tdc-gp30/ and
look for the latest revision of TDC-GP30_EvalSW.

2Quick Start Guide
This section describes how to quickly set up the GP30-DEV-KIT, establish basic operation and make
measurements.
2.1 Install the Software
It is crucial to install the software before connecting the evaluation kit to your computer. A default
driver loading of your OS may interfere with correct installation.
•Download the latest zipped software installation package to the desired directory.
•Unzip the package to the desired directory.
•Open “setup.exe” from the unzipped directory.
•Follow the instructions on the screen.
2.2 Install the Hardware
•Make sure software is installed correctly before proceeding with this step!
•Connect your computer with the PicoProg Lite using USB cable.
•Connect PicoProg Lite and the evaluation kit reference board.
•The green LED on the evaluation kit should be on.
•Connect your spool piece to US_UP and US_DOWN
2.3 Quick Start for Initial Measurements
From the “Start” menu, go to “All Programs” and then to the “ScioSense” directory. Double click the
“GP30_v2_0” icon (or newer versions, if available) to begin execution of the evaluation software.
The following screen should appear:

Figure 2: Functional Blocks
•Click the “Verify Interface” button to confirm communication between PicoProg Lite and
TDC-GP30 is working. Both fields, “Pico Prog Lite FW version” and “Comm. With GP30 OK?”,
should become green.
•Next, open our initial configuration GP30Y_config_default_03 and download it into the chip,
pressing “Write Config”.
•Connect your spool piece to pins US_UP and US_DOWN. Depending on the outline of the
transducers changes of the configuration will be necessary.
•Press “Start Measurement” to begin measuring.
At this point, after successful completion of the above steps, a basic operation of the DEV kit should
be possible. The following sections provide a detailed description of the hardware and software for
advanced operation.

3Hardware Description
3.1 Introduction
The GP30-DEV MODULE board, shown in Figure 3, is a front-end for a water or heat meters. The
transducers and temperature sensors are directly connected to this board. It comes with a 32.768 kHz
quartz (X2) and a 4 MHz ceramic oscillator (X1). All ports of TDC-GP30 are available. Additional patch
fields allow an easy extension with additional circuits. Those can be amplifiers or analog switches
for operation in gas meter mode.
Figure 3: GP30-DEV MODULE
3.2 Communication Interface
The PicoProg Lite board is a USB-to-SPI converter box that interfaces all UFC evaluation systems.
The PicoProg Lite is registered by the operating system initially as “PicoProg LITE V1.0”. To confirm,
open “Control Panel” of your OS and click on “Devices and Printers” icon. The USB driver will be
listed in “Unspecified” driver section.
The flat connector includes the power lines and the SPI or UART communication lines. The
development kit with PicoProg Lite does not support UART communication.
On the demo board the communication interface is initially selected to SPI (by solder bridge LJ2).
Pin VCC_LEVEL is the voltage feedback for the former PICOPROG level shifters and is no longer used
with PicoProg Lite.

4.1 Measurement
When started, the software comes up with the main window, showing the “Measurements” tab.
Figure 4: Main Window
4.1.1 First Step with Measurement Control Elements
A good first step is to load a working configuration and make measurements in frontend mode
(without using the internal 32-Bit µP). ScioSense provides a sample configuration file named
GP30Y_config_default_03 which typically works well with DN20 spool pieces.
Load Configuration File: File menu →Open Config →choose appropriate configuration file
1. Press “System Reset” button. Now the Pico Prog Lite FW version field should get green
and the appropriate version should be displayed (1.2.1 or higher). Further, “Comm GP30
OK?” should get green to show that communication with TDC-GP30 works.
2. If watchdog is not disabled by “System Reset”. Button press “Disable Watchdog” button.
3. Press “Write Config” button to download the configuration settings into TDCX-GP30.
4. Press “Start Measurement” button. Now the chip starts to measure and the software
displays the results in the table “Time of Flight Measurements”.
The user can now modify the configuration to fit it to his needs. Having done this, the user can store
his own configuration files.

4.1.2 Time of Flight Measurement Results
GP30 stores the first 8 hits of every TOF direction separately and also the averaged sum of all
measured hits calculated by UI (in blue). These 9 results are displayed for both directions, as we call
them up and down. The evaluation software additionally calculates the difference (in blue) between
up and down stream, DIFF-TOF. In total, all 27 results are displayed in the “Results” column.
In the “Average” column the user can set the sample size for the averaging (<1000). The software
calculates the rolling average of the results accordingly. In “Std. Dev.” column the standard
deviation, calculated over a variable sample size, is displayed. The number of samples can be chosen
(e.g. 100).
The same is done with the amplitude values of the receiving signals and the pulse width ratio between
first hit and start hit. The values for both directions are displayed.
Information: The application of the highspeed calibration is off by default. This is more convenient
when comparing measurement data. But when collecting data for calibration it is strongly
recommended to have this active.
Figure 5: HS Clock Calibration
A graph to display TOF measurement results opens in a separate window by pressing “TOF Graph”
button. It is possible to activate up to four plots. Each plot has various selections, e.g. TOF1UP,
TOF2UP etc.. Always averaged values are displayed.

or the full data.

4.1.3 2-Wire Temperature Measurement Results
A graph to display temperature measurement results opens in a separate window by “Temperature
Graph” button, similar to TOF graph.

4.2 Ultrasonic Measurement Control
In this tab the user makes all settings for an appropriate ultrasonic measurement. They group as
follows:
•Time of Flight Sequence Control
•Time of Flight Hit Control
•Amplitude Measurement Control
•Transducer Interface Options
