BTW. I did manage to open the speaker without too much damage (thank you for telling me how), but have not done any soldering yet...

Further more: I read that the Arduino wire library uses a 32-byte buffer. This means the total bytes send upon endTransmission() should be no more than 32 bytes, I guess...

Hi Stephan, Today I did some soldering and have some interesting results. I'll keep it to some main points as I'm still testing: - The I2C scanner sketch correctly reports...

Hi Stephan, I just tested your second version. Very nice result! I like how you changed your code to send the frame in two parts. My own attempt was much...

BTW, this is where I soldered my Dupont connector. I used the unpopulated capacitor spot C1 (for Vcc and Gnd) and some magnet wire plus kapton tape. The A0 pulldown...

Hi Stephan, just a short message to let you know that I'm working on a setPixel function. My progress so far is promising I've mapped about half of the pixels...

I have removed some clutter and made a trimmed down example sketch (testing now, uploading soon...). Once done, the addressing makes slightly more sense, but getting there was quite painful,...

Here is my setPixel test sketch: https://gist.github.com/maxint-rd/e3abafc315e5b578b79cc0bb75641ef2 I used your code as base and added some functions and comments. Hope it works for you. (Use at your own risk! :-)...

For completeness here are some findings (also mentioned in the comments of the setPixel tryout sketch): - We need to map 11 x 11 x 3 pixel-leds to a proper...

The coming week I won't have much time for further work on this. Thank you for your cooperation. I think that working together, we reached some nice results in a...
