go-urm09driver

This is a Go module useful for controlling the URM09 ultrasonic ranging sensor on a Raspberry Pi or similar devices. The board is controlled over i2c.

Note: this driver is by no means done or fully tested.

Installation

go get github.com/MrBuggy-Amsterdam/go-urm09driver

Usage

After initializing the sensor on a specific bus (the i2c device used) and address (0x11 by default) you will have access to the ReadDinstance() function and can also enable passive mode as shown below (See the official docs).

package main

import (
    urm09 "github.com/MrBuggy-Amsterdam/go-urm09driver"
)

func main() {
	urm := urm09.Initialize(1, 0x11)

	// Enable passive mode for  on-demand ranging
	err := urm.EnablePassiveMode()
	if err != nil {
		// Do something with the error
	}

	distance, err := urm.ReadDistance()
	if err != nil {
		// Do something with the error
	}
}

Troubleshooting

A good start is to use i2cdetect to scan your i2c bus and confirm that your device is connected. Also make sure to read the official docs.
