Erratic behaviour about clodiuno HOT 10 CLOSED

I've merged your pull request.

No idea about the dotimes behaviour, I'll look into it.

from clodiuno.

Doesn't fix issue for me. :( As I can see :digital-in in conn is nil for me.

(ns clojure-arduino.core
  (:use :reload-all clodiuno.core)
  (:use :reload-all clodiuno.firmata))

(System/setProperty "gnu.io.rxtx.SerialPorts" "/dev/ttyACM0")

(defn -main []
  (let [board (arduino :firmata "/dev/ttyACM0")]
    (println @board)
    (Thread/sleep 5000)
    (pin-mode board 12 OUTPUT)
    (digital-write board 12 HIGH)
    (close board)))

Should be fixed now. I've manually populated digital in/out ports. Tested on Mega.

Hi,

ahhh, i think your problem is elsewhere. I did struggle with this the all week end.

What's your linux distribution ?

On Ubuntu the devices is not seen by the underlying api clodiuno uses RXTXcomm.jar - i opened a pull request to notify @samaaron about this on his api https://github.com/samaaron/serial-port (which does some of the stuff clodiuno does) - https://github.com/samaaron/serial-port/pull/4/files

You must link your device with a name that starts with /dev/ttySxx something else it is not seen.

For me, i did this:

ln -s /dev/ttyACM0 /dev/ttyS42

Hope this helps.

You can work around that by adding,

(System/setProperty "gnu.io.rxtx.SerialPorts" "/dev/ttyACM0")

I've tested it on an Ubuntu 12 with a Mega 2560 which also registers as /dev/ttyACM0.

Thanks, did not know that :D
I will try your fix now.

Thanks again

All is working for me - even the tips!
