nmea0183-checksum
Tiny CLI program that generates a NMEA0183 checksum for any given sentence
Installation
[sudo] npm install -g nmea0183-checksumUsage (CLI)
$ nmea0183-checksum '$SDHDG,181.9,,,0.6,E'
> $SDHDG,181.9,,,0.6,E*32Usage (programmatically)
This program exposes a single function: getCheckSum(sentence, [returnHex]).
You can use it to calculate the checksum of a given sentence. Example:
const getCheckSum = require('nmea0183-checksum')
const sentence = '$SDHDG,181.9,,,0.6,E'
// Returns hex string 32 (default behaviour)
let checksum = getCheckSum(sentence)
// Returns 50 (base10 integer)
let checksum = getCheckSum(sentence, false)License
