3 Hardware Description
3.1 Introduction
The GP30-EVA MODULE board, shown in figure 3, s the front-end for a water or heat meter. The
transducers and temperature sensors can be connected directly 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.

3.2 Communication Interface
The PICOPROG device is a USB-to-SPI converter box that interfaces all UFC evaluation systems.
With version 3.0, the PICOPROG also supports the USB-to-UART conversion of TDC-GP30. The
PICOPROG is registered by the operating system initially as “picoprog v3.0 unprogrammed”. As
soon as the GP30 evaluation software starts, a special firmware is written into the PICOPROG to
handle the SPI or UART communication with the TDC-GP30. The PICOPROG is now listed as
“UNIPRO” in the device manager. For SPI communication only, PICOPROG version 2.0 is
sufficient.
Figure 4 shows the connection between the PICOPROG and the GP30 board. The flat connector
includes the power lines and the SPI or UART communication lines. On the demo board the
communication interface is initially selected to SPI (by solder bridge LJ2).
VCC_LEVEL is the voltage feedback for the PICOPROG level shifters.

4 Software Description
4.1 Measurement
When started, the software comes up with the main window, showing the “Measurements” tab.
Figure 7 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). ams provides a sample configuration file named
GP30Y_config_default_A1.A2.11.03 which typically works well with DN20 spool pieces.
Load configuration file: File menu Open Config choose appropriate configuration file
Next step: Press “System Reset” button. Now the PicoProg FW version field should get green
and the appropriate version should be displayed (20 or higher). Further, “Comm GP30 OK?”
should get green to show that communication with TDC-GP30 works.
Next step: If watchdog is not disabled by “System Reset” button press “Disable Watchdog”
button.
Next step: Press “Write Config” button to download the configuration settings into TDCX-GP30.
Next step: 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 sum of all measured hits.
These 9 results are displayed for both directions, as we call them up and down. The evaluation
software additionally calculates the difference 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.
Note: The high speed calibration is by default off. This is more convenient when comparing
measurement data. But when collecting data for calibration it is strongly recommended to have this
active.

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.

Under menu item “Assembler” the user finds the compile and download options. The download
option effects, that “Firmware Download” window is opened (see also below).
Whether the call of these functions was successful or not is indicated by the messages at the
bottom of the assembler window.
Download
This window allows the download of the firmware which is typically handeld by 2 files, one for the
“Firmware User Code” and one for the “Firmware Data”.
Figure 23
With “Check Status Flag”, the watchdog and the lock state of the GP30 can be checked.
Please make sure that the watchdog is disabled before starting a download or other
transactions in this window.
In the “Firmware User Code” section, a firmware user code file (*.hex), which is typically
generated by the assembler tool and intended for the user part of 4kx8 Program NVRAM,
can be loaded by pressing “Open File”.
In the “Firmware Data” section, a firmware data file (*.dat), which is intended for the 128x32
Data NVRAM, can be loaded by pressing “Open File”. This section also contains some
additional transfer options from GUI to FW Data 2 fields and from GP30 back to FW Data 2
fields.
By pressing “Download FW Code & Data” both files are stored in the corresponding
NVRAMs. This action takes a few seconds. After the download, both files are located in the
volatile as well in the non-volatile part of the appropriate NVRAMs. The download can be
combined with a lock option of the firmware.
When pressing “Download FW Code & Data” a possible auto running firmware program is
stopped. If a new proper auto running firmware program is downloaded, this firmware can
be started again by performing a system reset.

The last 4 addresses of FW Data 2 section contains the fields for the checksums which are
stored to GP30 when downloading firmware to GP30. These fields are directly updated,
when firmware files are loaded or contents of firmware data fields are changed.
If pressing the “Verify FW” button after downloading, the content of the NVRAMs can be
compared with the given files by their checksums. The software calculates the checksum of
the given files and reads the calculated checksums of GP30 as well as the stored
checksums at the end of FWD2 section. Then the checksums of every section are
compared to each other. In case of a successful programming all indicators have to be
green.
In the “Firmware Acam Code” section, the checksums for the firmware acam code are also
checked and displayed after a “Verify FW”. The firmware acam code cannot be modified by
user. Therefore a checksum calculated by software filed is missing in this section.
A lock state of GP30 or a hang-up, caused by a faulty firmware user code can be dissolved
by pressing “Erase FW” button. After that, a new firmware (user code & data) need to be
downloaded again.
CPU Values
This tab is only for customer who uses the acam firmware for flow calculation. It reads out
some important CPU values like water temperature, flow, velocity, etc. To enable the readout the
“Read calculated values” checkbox has to be set.
