    Ok... I just tried to upload the sketch I made in Processing to the arduino to the board - 

    I have to note that we had to modify the board to use an UNO chip because the ATmega that came with it seemed to have gotten corrupted :/ - The Uno was programing the examples from the Peggy 2 library with no problem. 

    Here is what I get when I try to verfiy/upload the sketch I just finished in processing. Again any help would be awesome. Thanks!

    The error indicates that you do not have the Peggy 2 library for Arduino installed, so it's more of a failure-to-install-software fail, rather than a Peggy fail.  Please download and install that library and restart Arduino before trying again.

    Hhmmm... I thought I did that... you just download the Peggy2 folder and put it in the libraries subfolder of arudino correct? and yeah... the peggy hardware works fine... its a programming issue (I'm a lot better with tactile things, just learning to program recently) 

    Here's a http://www.flickr.com/photos/90777409@N02/9304471116/

    Maybe I have the Peggydraw_heartart in a wrong relationship to it? - thanks for your help and your answer on the animation possibilities. 
  • Windell OskayWindell Oskay
    Yes, that installation looks correct; try restarting Arduino to see if it is installed correctly.

    (And, after years of helping people to debug issues like this, your description, with that one picture of where it goes is *by far* the clearest illustration that I've ever seen-- thank you!)

    If the library is installed correctly, you should see Peggy2 listed in your File>Examples menu within Arduino. 
  • SuMo_DSuMo_D
    Yes, the Peggy2 File>Examples menu works fine and programs in (loads to the board) just fine. I spent some time this morning going through and loading all of them and doing simple mods to get a feel for the code and it uses. 

    The Peggydraw however and the Peggydraw_heartart both still are showing the same errors :( - I want to try to get my own content on here with it... which... will happen eventually!

    Also yeah, appreciate the compliment I used to teach graphics programs (Adobe Suite) at a major art school so tried to got my ninja screenshot skills down ;) - I had a bout with cancer and my head isn't always all there but I'm going to start teaching again in the fall so glad its coming back :)

    Oh-- I see --I have made a mistake here, and I do apologize.  

    I had mistaken the source of the "does not name a type" error, which almost always indicates that one of the Arduino libraries is not installed. However, that's not what's going on here.  What's actually going on is that you've opened up the Processing application itself (PeggyDraw 2)-- not the output file that it created.  When you save a file in PeggyDraw 2, it shows up in the data/PeggyProgram folder-- and *that* is the output that you should open with Arduino. 





  • SuMo_DSuMo_D
    Ok.... Closer but still no... :/ now a whole different error... but it seems like its almost there...

    so it is setup lke... http://www.flickr.com/photos/90777409@N02/9302093837/

    I get it to run the program and save it, it looks like     http://www.flickr.com/photos/90777409@N02/9304957540/
    Which seems a lot more like what it should be... and is awesome

    but when I open PeggyProgram.pde with arduino and try to run it I get

    Can you please paste the contents of the Peggy program?

    Okay, this file doesn't actually look like the one that PeggyDraw 2 generates for me-- is it possible that you're using the old, deprecated version of PeggyDraw 2?   I'd suggest that you download a fresh copy:  http://code.google.com/p/peggy/downloads/detail?name=PeggyDraw2, v1.1.zip
  • SuMo_DSuMo_D
    DUDE!!!!!!!!!!!!  Check this out!!! 

    :D

    its my 3 year stem cell transplantaversary as of 55 minutes ago... this is a tremendously awesome way to start it :D

    Thanks again Evil Genius you! Fresh v1.1 for fresh code! Word! 
  • Windell OskayWindell Oskay
    Okay-- great!  And, again, my apology for not catching that initial error correctly the first time.

  • SuMo_DSuMo_D
    No worries man! Thanks for all your help! 

    One more question, I'd really love to do more with programming in variable shades, I know you briefly touched on that in the other thread you split my questions into, do you have any suggestions for places/resources to study up on doing that?

    This will def get me through the event this weekend but we're going to be using this in our kids programming classes too I think and want to try to get more versed in how the actual code works. We have one or two arduino masters at our maker space, but they're not always around...

    The Peggy 2 hardware-- natively --only knows about on and off. However, the refresh rate is very high, so we can simulate multiple brightness levels by trading off refresh rate, and lighting some of the LEDs for only part of the time-- quite convincingly to the eye. We show off this capability in a few of the demo programs, and also use it in the "Peggy 2 video" examples, where we let the Peggy 2 receive serial-streamed data with 16 levels of brightness. You might want to look at those examples as a starting point. 


    For PeggyDraw 2, we wanted to make it simple to use and able to draw a lot of frames (~250), so it's single-level on/off. If we rewrote it to use 16 grayscale levels, that would requires four times as much memory (4 bits per LED), so only 1/4 as many frames could be stored in memory, or about 60 frames maximum. Perhaps 8 gray levels (3 bits per LED) would be a better choice, giving about 120 frames available.
