lidar-transport installation

A project for connecting RP LiDAR devices from a raspberry pi to any other device over socket.io.

Works well with vizdar;

usage

$ git clone [e-mail]:hugohil/lidar-transport.git
$ cd lidar-transport/
$ npm i
$ ./bin/linux/print-lidar --port '/dev/ttyUSB0' | ./main.mjs --address="127.0.0.1" --port=3000 # these are the default values

lidar-transport comes with prebuild binaries for linux (raspberry pi) and macos only, feel free to make a PR and add builds for other platforms.

toolbox

headless ssh raspberry setup

building print-lidar from the sources

$ mkdir sources && cd $_
$ git clone [e-mail]:hugohil/rplidar_sdk.git
$ cd rplidar_sdk
$ make
$ cd output/Linux/Release/
$ ./print-lidar --port /dev/ttyUSB0 115200

you should see logs in the following format:

S;...{angle;distance;}E;

for example:
S;0.543823;315.000000;1.043701;318.000000;1.955566;0.000000;2.120361;323.000000;3.081665;[...];357.385254;298.000000;357.890625;301.000000;358.401489;304.000000;358.967285;307.000000;359.467163;310.000000;359.983521;312.000000;E;

note: angle is in degree (0-360) and distance is in mm.
