Where has the Stefan Petrick "Electric Mandala"/Teensy/Arduino code moved to? I've been reaquinted my SmartMatrix display which is hooked up to a Teensy 3.1 board and I'm wanting to see "Electric Mandala" by Stefan Petrick running on my setup. Does anyone know where the code resides on the...

I've been searching many sites looking for a hookup schematic for attaching the MSGEQ7 board to my Teensy 4.1 chip. I can't find any hook up guides. Anyone? Remember, pictures are worth 1000 words. Thanks in advance.

So here's the thing: I have a defunct (no longer working due to excessive voltage but Teensy 3.2 works just fine) SmartMatrix SD board with SD card slot attached and I would like to purchase another one (replace) for my HUB75 SmartMatrix display. The problem is there are no longer any available...

Still after over one week able to resolve my compile issues. Where did everyone go. I've D/L'ed the most recent Libraries, Sketches and still not able to get up to speed. Running on an iMac High Sierra 10.13.6 - Arduino 1.8.19 - Teensyduino 1.56 - SDShield Teensy 3.1 I did get Featuredemo...

Still not able to compile and all libraries are present and accounted for. Here's the last error code I get and it can't find what IS in the libraries folder. Any clues as to what' s happening? #Using library SD at version 2.0.0 in folder...

Don't need T4 adapter as I don't have one. You'll see in the code line 77 that I've blocked it out as it's not necessary.

I didn’t know I was duplicating the topic. I was just replying.

Don't need T4 adapter as I don't have one. You'll see in the code line 77 that I've blocked it out as it's not necessary. Again here are the error codes and thanks again for looking: Arduino: 1.8.19 (Mac OS X), TD: 1.56, Board: "Teensy 3.2 / 3.1, Serial, 96 MHz (overclock), Faster, US...

Upgrade didn't help. Still not able to compile. Here are error codes: Arduino: 1.8.19 (Mac OS X), TD: 1.56, Board: "Teensy 3.2 / 3.1, Serial, 96 MHz (overclock), Faster, US English"...

Running Arduino 1.8.19 & TeensyDuino 1.56 on iMac 10.13.6 High Sierra but unable to get AnimatedGIFs compiled on IDE. Error codes: Arduino: 1.8.19 (Mac OS X), TD: 1.56, Board: "Teensy 3.2 / 3.1, Serial, 96 MHz (overclock), Faster, US English"...

Thank you for that information. I'm puzzled as to why you say this as I am looking right at FilenameFunctions.cpp & FilenameFunctions.h which are attached within the Teensy GIF program. First tab is the .INO GIF player, second tab is FilenameFunctions.cpp and third tab is FilenameFunctions.h...

As requested here is the verbatim error message: Arduino: 1.8.13 (Mac OS X), TD: 1.55, Board: "Teensy 3.2 / 3.1, Serial, 96 MHz (overclock), Faster, US English" /Users/alfredolivas/Desktop/Desktop - Alfred’s iMac - 1/Arduino/Arduino.app/Contents/Java/arduino-builder -dump-prefs...

Too many and constantly changing errors to deal with. Doesn't help to download latest sketch. It's all crapped out. Perhaps its in the .h system of files. I just don't know anymore.

So now a new error message appears: code: if(initFileSystem(SD_CS) < 0) {#if (ENABLE_SCROLLING == 1) error: 'initFileSystem' was not declared in this scope Another error pops up not of my making...

Code was correct Code was fine I just typed it with the wrong brackets. Still the same problem. Won’t compile for my Teensy 3.1 M

NOPE - Tried the changes here as suggested and still get the same error. Arduino: 1.8.13 (Mac OS X), TD: 1.55, Board: "Teensy 3.2 / 3.1, Serial, 96 MHz (overclock), Faster, US English" /Users/alfredolivas/Desktop/Desktop - Alfred’s iMac -...

I have a Teensy 3.1 board attached to a SmartMatrix via the Pixel.mx SmartMatrix SD shield. Last October (2021) I uploaded a sketch that, when run, ran through all my GIFs within the SD card inserted into the board. Earlier this past week the display started doing strange things, green bars...
