<div dir="ltr"><div><div>Hi everyone<br><br></div><div>An update/more questions<br><br></div>Yep I got Arduino talking to ChucK now with the<b> <a href="http://ints.ck">ints.ck</a> </b>script in the Serial folder under examples (don’t know why it wasn’t there so I just downloaded source/help files again!). Although I cant seem get <b>seiralRecvArduino_3.ck</b> to receive any data from my Arduino. Is there a way of modifying<b> <a href="http://ints.ck">ints.ck</a> </b>to receive /parse the incoming values from my x4 potentiometer?<br>
<br></div><div>Thanks for any explanations/advice-much appreciated!<br></div><div><br><br></div><div>Alan<br><br></div><div>My Arduino code is below<br><br><br>// the setup routine runs once when you press reset:<br>void setup() {<br>

The Firmata protocol has a more or less midi format (sysex) and can be parsed by standard midi interpreters/parsers. I haven't looked at the ChucK midi support but it may be that 95% of the code needed for a Firmata client is already in that package. In fact it might be easiest to implement a Firmata client as a special mode of the standard ChucK midi package.<div>
<br></div><div>The nice thing about it is that the Firmata firmware gets serious maintenance so you basically just load it to the Arduino and it works. It can read most standard sensors that plug into the Arduino. It was originally written to allow processing apps to read Arduino sensors and display the results allowing processing to basically be a gui front end for an Arduino. Firmata client libraries/plugins are now available in a variety of languages including PureData as Alan mentioned earlier. It has become the defacto way to access Arduino sensors from a remote host via a serial port. ChucK absolutely needs someone to write a Firmata client library and it should be bundled with the core ChucK package. It would make using Arduino sensors in ChucK a simple plug and play, basically bug free operation. A lot of work has already been done to connect various sensors/controllers to music systems using Arduino/Firmata. Making all of that work available to ChucK users would be a big win.<div>
<br></div><div>The protocol is documented here:</div><div><br></div><div><a href="http://firmata.org/wiki/V2.3ProtocolDetails" target="_blank">http://firmata.org/wiki/V2.3ProtocolDetails</a><br></div><div><br></div><div>
Firmata doesn't solve every possible Arduinio interface need but it covers 95% of what most people want to do.</div>

<div>Thanks for your reply and thoughts, much
appreciated...hmm I'm not getting Arduino & ChucK to
Communicate at the moment but I think I need to work more
on my Arduino code more to communicate with ChucK- up to
now I have been using Firmata with Pure Data, which only
requires the the Firmata sketch to upload. As you say
there is a lot of stuff here to look at so will report
back :)</div>

<div dir="ltr">Hi Al,
<div><br>
</div>
<div>If you check out the chuck examples folder that
came in the chuck download or in the "Open Example"
menu item, there should be a "serial" subcategory with
some basic examples of communicating with serial
devices (e.g. Arduino) in there. </div>
<div><br>
</div>
<div>What I would recommend is sending your 5 analog
values as a space separated series of ASCII numbers,
ending with a newline, and repeating this at whatever
your desired refresh rate is. In ChucK, you can use
onLine()/getLine() (as in the <a href="http://lines.ck" target="_blank">lines.ck</a> example) to get each
line of data, which includes all 5 current sensor
values. There is also a (minimally documented) RegEx
class you can use to pull out the values individually
and then convert them to integers. </div>
<div><br>
</div>
<div>Ive also attached another ChucK example I have that
does something very similar to this, except it reads
only 3 sensor values and uses commas to separate
values. </div>
<div><br>
</div>
<div>Thats a lot of stuff, so let us know if you have
any more questions. </div>

<div>Hi there<br>
<br>
</div>
I am using ChucK 1.3.2.0 (Chimera) with
miniAudicle 1.3.0a on Ubuntu 12.04- I think
the latest version can communicate with
Arduino directly? Cant seem to find any
examples so any advice or example code
would be much appreciated. I am trying to
build a simple step sequencer with <cite><b>x5
potentiometer</b>s </cite>that send
values to an arduino board and then into
ChucK hopefully. Was hoping I could do this
without OSC- <br>
<br>
thanks for helping this noob!<br>
