  • Page 3: Introduction

    Introduction Introduction 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.

    Document Feedback TDC-GP30 Hardware Description Hardware Description Introduction The GP30-DEMO MODULE board, shown in Figure 5, 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).
  • Page 9 Document Feedback TDC-GP30 Hardware Description 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.

  • Page 10: Software Description

    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.
  • Page 11 Document Feedback TDC-GP30 Software Description 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. If watchdog is not disabled by “System Reset”.

    Reference Modules and Transducers Modules ams has a close cooperation with Qingdao iESLab to support customers with complete ultrasonic flow modules for water and gas. For water, iESLab offers pipes made of brass and made of plastic and modules can be ordered un-calibrated or calibrated. The gas meter modules are made of plastic and come un-calibrated, as the final housing will have a major impact on the calibration.
