MSP430 Gas Metering Library  1_10_00_11

Release Notes 

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

• MSP430FR5994

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

Dependencies
