# MSP430 Gas Metering Library 1_10_00_11

## Release Notes

Document Revision: April 26, 2017

## Introduction

Library provides the means to configure the internal ADC for ultrasonic captures and help to integrate it with the application software for development of Gas Meter Ultrasonic Flow Meter applications. The library also takes advantage of LEA module in MSP43FR5994 devices to compute ToF measurements.

## Installation and Usage

## Device Support

The following families of devices are support in this release of MSP430 Gas Metering Library:

- MSP430FR5994

## This is the 1_10_00_11 release of MSP430 Gas Metering Library.

## Dependencies

- CCS v6.1.3 or later
- IAR for MSP430 v6.40.2 or later

## Validation Information

This is library version has validated. This build has passed functional library testing and basic system level testing.

Validation:

- Long overnight tests at room temperature

## Upgrade and Compatibility Information

## Examples

The examples may be built with CCS and IAR for MSP430.

## Known Issues

- Break after long run (suspect this is same as the GUI issue): 1 hr with 8 Hz measurement rate and likely after 2 days with 1 Hz measurement rate

## Versioning

This is build 1_10_00_11 of MSP430 Gas Metering library.
