golight

A go package for turning a Delcom led light red, green, or yellow.

Installation

This project depends on go.hid which is a wrapper for signal11/hidapi.

To install hidapi:

git clone git@github.com:signal11/hidapi.git
cd hidapi
./bootstrap
./configure

On OSX I found that bootstrap required automake and other packages.

sudo port install automake autoconf libtool

For linux + hidraw: cd linux. (requires libudev. Package libudev-dev on debian/ubuntu.)

For linux + libusb: cd libusb. (requires libusb. Package libusb-1.0-0-dev on debian/ubuntu.)

For mac: cd mac.

For windows: cd windows.

Make and install. For linux/mac:

make
sudo make install

Lastly, for linux only: Create a symlink pointing libhidapi.so to the version you chose:

For linux + hidraw: cd /usr/local/lib; sudo ln -s libhidapi-hidraw.so libhidapi.so

For linux + libusb: cd /usr/local/lib; sudo ln -s libhidapi-libusb.so libhidapi.so

For more instructions on libhidapi, please visit signal11/hidapi.

When you have installed hidapi lib, install go.hid package with go get github.com/GeertJohan/go.hid.

Then install this package with go get github.com/erichhansen/golight

Usage

There are 3 main methods - On, Off, and Flash.

• On Turn light on
