Using clj-firmata with Clojurescript

clj-firmata is supported in Clojurescript on Node.js targets.

Setup

First, you'll need to install node-serialport in your project:

> npm install serialport  

Build your application as you would normally.

Differences from Clojure

The main difference is in opening a board. Unlike the Clojure version of open-board and its siblings, the Clojurescript version takes a callback. For example, opening a serial board:

(ns my-firmata-app
    (:require [firmata.core :as f]))
(defn -main []
 (f/open-serial-board "/dev/tty.usbmodemfd131" (fn [board]
    ; do what you like here with the standard clj-firmata api
    ))

Detecting a valid arduino serial port works in a similar manner. In this instance the callback takes the form (fn [err port]). For example:

(detect-arduino-port (fn [err port]
      (if port
        (f/open-serial-board port (fn [board]
            ; do stuff with the board
            ))
        (if err (print err) "No port detected"))))
