Developing Flow meter design for Water, Gas and Heat meters with the Ultra-low-power MSP430FRx FRAM microcontroller Family is now enabled by the EVM430-FR6989 reference board. The EVM430-FR6989 (Water Meter reference design) kit is an easy-to-use Evaluation Module for the MSP430FR698x family of microcontrollers. It contains everything needed to start developing a flow meter on MSP430FR698x platform based MSP430 MCU, including on-board emulation for programming and debugging.

This reference design consists of three boards. The main board of the EVM is built on MCU MSP430FR6989 with LCD display. A battery socket is on the back of the board to provide 3.0 V. Next is the sensors board. The sensor board is designed for LC sensor. The third board in this setup is the motor board. The motor board is to drive the rotor disc to simulate water or gas flow. There is a battery socket on the back of this board.

This tool has been built to demonstrate the capability of FR69x devices in the Flow meter markets and to aid designers with rapid prototyping and faster design cycles.

The bundle kit comprising of the EVM430-FR6989 Water meter reference platform and is available for purchase from the TI eStore.

To make setup easy, we have the new FlowESI GUI for simple configuration of code based on the sensors being connected to the extended scan interface. Free software development tools are also available, such as TI’s Eclipse-based Code Composer Studio and IAR Embedded Workbench.

The ECCN (Export Control Classification Number) classification for this tool will be the same as the included microcontrollers. To find ECCN information for a microcontroller, see the datasheet for that device.

Any use made of Texas Instruments (TI) classifications, whether it be ECCNs or HTS, is without recourse to TI and at the user’s risk. HTS and export classifications are subject to change. Your company, as the exporter of record, is responsible for determining the correct classification of any item at the time of export. Any HTS or export classification by TI is for TI’s internal use only and shall not be construed as a representation or warranty regarding the proper export classification nor relied upon to make licensing determinations.
