I could not get the arduino pro mini to work with just comport no matter how i tried, so i installed "Pduino" and after installing
pd-mapping, pd-pure, pd-moocow [pdstring] i got it to work Patrick Pagano B.S, M.F.A Audio and Projection Design Faculty Digital Worlds Institute University of Florida, USA (352)294-2020 ________________________________ From: Pd-list <[email protected]> on behalf of Richie Cyngler <[email protected]> Sent: Monday, September 21, 2015 10:35 PM To: Martin Peach Cc: [email protected]; IOhannes m zmölnig Subject: Re: [PD] Pduino and arudino mini pro/raspi debian- Pduino or Comport? Funny I was just working on this this morning looking for a simple solution for my students. I found this http://colinzyskowski.com/?page_id=503 to access analogRead. It kind of works. The third pot interferes with the other two and when I modified to code to add a fourth it interfers or doesn't work at all. Seems to be something to do with the map function Arduino code not workign correctly because when I poll [comport] with [print] each analogRead seems to be on it's own "channel". I can't figure out how to separate them any better than using [split] with there mapped values (not great). I tried [unpack] and [route] but neither of these separate the data streams. On the hardware side I just have each 10k pot wiper connected it's own analog pin on the Uno and each pot is powered and grounded from the Uno via the rails on my breadboard. I'm guessing but adding in some resistors might stabilise the circuit a bit, I don't know if this would help with the interference or not. As mentioned above I also had to add a dialout to access the serial port as outlined by Rinzwind here http://askubuntu.com/questions/58119/changing-permissions-on-serial-port On Tue, Sep 22, 2015 at 8:45 AM, Martin Peach <[email protected]<mailto:[email protected]>> wrote: ...and connect Tx to Rx and Rx to Tx and don't forget to connect the grounds together.
