GP30-DEV-KIT
Introduction
1.1 General
The GP30-DEV-KIT is designed as a platform for a
quick and easy start-up and evaluation of the TDCGP30 Ultrasonic Flow Converter. 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 to refer to the latest TDC-GP30
datasheets. Please request them from acam.
1.2 System Components
The GP30-DEV-KIT includes the following
components:
GP30-DEMO--PCB: Small demo board with TDC-GP30, assembled with DSUB15 cable
PICOPROG V3.0: USB-to-SPI/UART communication interface
USB cable: For connecting the PICOPROG communication Interface to the local PC
CD-ROM: Contains software, drivers, examples and technical documentation
The GP30-DEMO-PCB is connected to the PC via the PICOPROG SPI-to-USB converter.

2.2 Communication Interface
The PICOPROG device is acam’s standard USB-to-SPI converter box that interfaces all acam
evaluation systems. With version 3.0, the PICOPROG also supports the USB-to-UART conversion of
GP30. The PICOPROG is registered by operating system initially as “picoprog v 3.0 unprogrammed”.
As soon as the GP30 evaluation software is started, a special firmware is written into the PICOPROG
to make the SPI or UART communication with the GP30. For SPI communication only, PICOPROG
version 2.0 is sufficient.
Figure 2.2 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 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.

Software Installation
The GP30 evaluation software described here is an early version for use with the TDC -GP30. It is
continuously under evaluation and subject to on-going improvement. Please hold contact with acam
to be informed about latest revisions.
The description herein is based on software version 1.2.7
Figure 3
To install the software, go to folder
GP30y_Software\acam GP30 Installer v1_2_7\
Volume and run setup.exe. Follow the
instructions. After starting the software the
PICOPROG is listed under devices and printers
as “UNIPROG”.
If not, go to the drivers folder , e.g.
GP30_Confidential\drivers\Win7_8 and install
the driver for your operating system manually.
In case of an upgrade of the software to a newer
version please make sure that the software uses
the latest driver. The driver is located in
C:\Program Files (x86)\acammesselectronic\GP30\data.
Therefore open the USB communications window and check the firmware version of the PICOPROG.
It should be version PicoProg_GP30_v21.hex or higher:

Software Tabs in Main Window
4.1 Measurement
When started, the software comes up with the main window, showing the “Measurement” tab.
Figure 5 Main window
4.1.1
First step with measurement control elements
A good first step is to load a working configuration and make measurement s in frontend mode
(without using the internal 32-Bit µP). acam provides some sample configuration files the software
which are working well. Please use those for a first measurement
Load configuration file: File menu Open Config choose appropriate config 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). Also “Comm GP30 OK?” should
get green to show that communication with GP30 works.
Next step: If watchdog is not disabled by “System Reset” button press “Disable Watchdog”
button.
Next step: Press “Write Config” button. Now the configuration settings are downloaded to GP30
and written to register area of GP30.
Next step: Press “Start measurement” button. Now the chip starts to measure and the results are
displayed in the tables of different measurements.

Now, this configuration can be modified to fit the user’s needs. In the end 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.
For both directions these 9 results are displayed. The evaluation software additionally calculates the
difference between up and downstream, 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 (
