    I guess I could also just have (for example) 4 boards per teensy, and then have one 'master' board that sends data over to the correct 'slaves'. The image is not changing that fast in my installation, so a little less...

    Thanks for your reply! Just wondering if you ment to say; 640 pixels * 32 rows (typed 16 in post) * 50-60 times per second. Cause if you actually ment to say 16, I wonder why it would be 16 instead of 32, as the board...

    Hi peeps, I'm planning to make an installation that makes use of a bunch of (preferably daisy-chained) LED matrixes like this Adafruit one; https://www.adafruit.com/product/2278 Before I buy anything I'd like to...

    The two boards are sending over RGB data that I convert from 8-bit RGB into a frequency range of 85-400hz. This (rather odd) protocol is part of an art installation I'm making. The chosen frequencies are there because...

    Okay, so I'm trying my best to thoroughly understand this ;) The algorithm will ALWAYS calculate at least 24 blocks, using about 70ms. It will then output the number of frequency that it is most confident of being...

    I mean; notefreq1.available() is true only 2 to 3 times when i cycle through it, which is when I call notefreq1.read() and save that value. I do have a 5ms delay in the loop at the moment. But I think that should...

    Hey Duff, Thanks for the answer, so far pretty much all code is in place, and saving and such. Basically one teensy works as a sender beeping of sine-waves in different frequencies. Those then get picked up by the...

    I'm making an installation in which two seperate microcontrollers send over data by using frequency values. I've decided to use the notefreq (AudioAnalyzeNoteFrequency object) to do that detection. I want to sample the...
