I used the $W.data command in the chrome console, and I was able to get data at that time of the intensity of the wavelengths, I would like to be able to get constantly updating information, and export it to an arduino sketch, is there a command for that?
Hi, I believe you should be able to override the
$W.getCrossSection()function here: https://github.com/publiclab/spectral-workbench/blob/master/app/assets/javascripts/capture.js#L180and it'll run each time a sample is collected -- many times per second. Exciting to see what you're doing! Please share some build photos if you can! :-)
So when I typed "$W.getCrossSection()" into the console I got: TypeError: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The provided value is not of type '(CSSImageValue or HTMLImageElement or SVGImageElement or HTMLVideoElement or HTMLCanvasElement or ImageBitmap or OffscreenCanvas)' at Object.getCrossSection (capture-2378d6dbb368cce52b64ccc75b38a3a4.js:1) at :1:4
Did I do something wrong?
Also thank you! I see if I can make a little blog post with what I've done so far, or maybe once I finish.

Oh sorry, you have to redefine the function with a new one of your own, that can be a revision of the existing one, and it'll get called each frame. Make sense? I'm happy to review your code and offer tips.

Is there not a way to make chrome console repeat a command over a period of time?

Ah, there is!
setInterval-- but thegetCrossSectionfunction is already run using this technique. Can you share a link to your code so I can help troubleshoot? Happy new year!Is this a question? Click here to post it to the Questions page.
Ok so all I did was, $W.getCrossSection= $W.data; which gave me the data one time, then every half second I got "$W.getCrossSection is not a function" every half second.
I also tried to "override" by making this: https://docs.google.com/document/d/1cctjKW-4lCkrBZuILErFq1bBNidR6Igmm5zh9k_wvFo/edit?usp=sharing
but I'm not sure how to use it... or if it will work
