README

NU40C16

This is a small libary to read the Grove - Ultrasonic Ranger (spec) in golang.

This libary is a translation of Seeed_Arduino_UltrasonicRanger written in C++.

It depends on the libary github.com/stianeikeland/go-rpio/v4.

Usage

Install via go get gitlab.void-ptr.org/go/nu40c16, here is a small example:

package main

import (
 "github.com/d2r2/go-logger"
 "github.com/stianeikeland/go-rpio/v4"
 "gitlab.void-ptr.org/go/nu40c16"
)

var lg = logger.NewPackageLogger("example01", logger.InfoLevel)

func main() {
 logger.ChangePackageLogLevel("nu40c16", logger.InfoLevel)
 rpio.Open()
 defer rpio.Close()
 n := nu40c16.NewNU40C16(16)
 distance := n.MeasureInCentimeters()
 lg.Infof("distance %d cm", distance)
}

You can also run it directly via go run examples/example01/example01.go. Make sure you user is root or in the gpio group.
