Re: [chuck-users] Serial/Arduino & ChucK example

+1 to the Firmata interface idea. Joel On 01/02/2014 06:23 PM, Steve Morris wrote:

someone should do a ChucK interface to Firmata. It is a good starting point. Maybe I'll give it a whack.

Hi Spencer/Steve,

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 :)

Thanks again!

Hi Al,

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.

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 lines.ck http://lines.ck 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.

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.

Thats a lot of stuff, so let us know if you have any more questions.

Hi there

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 *x5 potentiometer*s that send values to an arduino board and then into ChucK hopefully. Was hoping I could do this without OSC-

thanks for helping this noob!

Al
