I mounted my Teensy 3.6 in a breadboard now, and I'm getting the same problem. Both with my own code and with the FastLED example demoreel100 EDIT: I found the problem. The problem was that I was using FastLED 3.1.8, the one that comes together with Teensyduino. I downloaded FasLED 3.3, and...

I can do that tomorrow (time for me to go to bed at the moment). Both the Teensy and my LED strips are connected to the same PSU though, so they should have common ground

Hello. I am trying to run my LED programs on a Teensy 3.6. They have usually been working fine with Teensy 3.2, but on the Teensy 3.6 the colors are wrong, and the LEDs flicker. I have an octo adaptor with female headers soldered on to it, and I have both Teensy 3.2 and 3.6 with pre soldered...

I know about FastLEDs ability for 16 outputs, which is what I hope to use. I am almost only animating FastLED-effects, and only taking in data in the form of OSC-messages from my ipad that I use to control my setup. Do you have any tips for how I should proceed if I want to check how much of the...

What I want want to do is 16 strips with 150 LEDs each. Would it be better then to use 8 outputs, and chain two and two strips you think? My main reason for not wanting to do that is that I have to make some significant changes in my code to make it work.

What I'm thinking about is using FastLEDs functionality for multiple outputs, and then just wiring the output pins of the Teensy to input pins on the octo boards. That should work right? Unless there is some special communication the Teensy does with the Octo adaptors that requires you to use...

I would like to to have more than 8 parallel LEDstrip outputs, and I'm wondering if it's possible to connect two octo boards to one Teensy 3.6?

Allright! I've checked the video, and I think I understand it a little better now. After watching the video I even think the peak module is better suited for the thing I'm trying to do now! And thank you so much for taking the time to write a response! I really appreciate it! It's a major...

Hello! I am making a LED installation that is reacting to audio. The idea is that I want to be able to control what frequency the LEDs should react to live, using Touch OSC. I've "wired up" an analog input to a biquad filter, and the biquad is "wired" to an FFT analyzer. I started with only...

Hi! I'm having a trouble figuring out how to make this happen, or even how to google it properly. I have an animation that makes a "wave" move through an matrix of LEDs. I can adjust the angle of the wave so it moved straight up in the Y-direction, or at an angle towards the corner. In order to...

This is something I haven't thought about, but there's definitely some of the arrays that could be defined as constants.

I've figured it out with help from the creator of FastLED. He replied on FastLEDs google+ group. His guess was that my gigantic arrays with LED data ended up overlapping some of the memory allocated by the OctoWS2811 thus causing wierd problems. And this seems to be correct, because when I...

I can do that of course: #define USE_OCTOWS2811 #include<OctoWS2811.h> #include<FastLED.h> #include <SLIPEncodedSerial.h> #include <OSCMessage.h> String readString; // FastLED provides these pre-conigured incandescent color profiles: // Candle, Tungsten40W, Tungsten100W, Halogen...

I'm suddenly facing an issue where my program running on a Teensy 3.2 stops when it reaches a FastLED.show(); I know this because I moved a serial print through my code, and my print does not get output to the console as soon as I move it after the first occurrence of FastLED.show(); I have...

Yes it does. I've used it as recently as two days ago.

Do you know if there are any programmable/addressable UV LEDs out there?

Yes, I did! I'm going to tweak the numbers som more to see if I can get the dimming even smoother :)

Thank you for your tips! I ended up using your method luni, with some modifications. I'm pretty happy with the result :)

Hey! I've made myself a 5x5 LED matrix. I'm trying to make an animation that starts in the middle and expands out in a circle. Could anyone help me get started on the math behind painting a circle on a matrix?

Cool, thanks! I will test this when I get home from work tonight! :)

Oh, sorry. I didn't post it because it's basically just the Spectrum Analyzer example that comes with FastLED or Teensyduino (I don't remember which) But here it is: // LED Audio Spectrum Analyzer Display // // Creates an impressive LED light show to music input // using Teensy 3.1 with the...

Hello! Yesterday I go the spectrum analyzer working with the LEDs I've installed in my roof at home. It was very cool to watch the music visually unfold above me :) Now I have to questions: 1. How can I make the spectrum analyzer effect more smooth? I'm thinking about making a delay in how fast...

System requirements from enviral-design.com says: But Touch Designer, the software GeoPix is made in, is Mac compatible according to their web page.

I've got to say I think it's really cool that you went back to my post and figured this out! This problem, I realise, was way beyond me, but I find it really interesting to read about what was actually causing the problem! Great work! :)

Hey Lucas! Really cool program! I've watched all the introduction videos you've made, and I'm going to try out geopix for a couple of projects I have. I'd like to make it work with a Teensy 3.2 over wifi. Do you have any tips? I'm not familiar with art-net yet, but I was thinking that I could...

I'm making a lamp, and I wanted to be able to turn the lamp on by simply putting my hand on top of it. I'm starting to think this is not possible with the touchRead-function of the Teensy. On an arduino I could use the capsense library, and by putting a high value resistor on the sensor make it...

I'm not sure how to achieve this though. I tried putting a copper tape, connected to ground, under the copper tape I'm using as sensor. I separated them from each other with a normal piece of tape and double checked that there was no connection. This, unfortunately, did not help.

I've just started experimenting with the touchRead()-function on a TeensyLC in order to make touch buttons. I have a setup with some copper tape that I put on a piece of wood, with a cable soldered to the tape. This cable is connected to a pin on my Teensy. I print the returned values to the...

I'm having a hard time believing that, because then the data wires for all 7 LED strips would've had to be broken. And it happened at the same time. I haven't tested out any simple code yet. I can try that. I haven't tried measuring the data pins with a volt meter either, but I can do that...

I've just recently run into a strange problem that I'm not able to solve :/ In my basement I have 7x 5m Neopixel strips from Adafruit in my ceiling. They are controlled with a Teensy 3.2 with an Octows adapter, and receives messages from an ESP8266. Suddenly, about a week ago, I noticed...

I figured it out! It was even more trivial than uint32_t vs uint16_t. This statement was never true: if (Index_LEDi[i] > TotalSteps) Changing it to this fixed the problem: if (Index_LEDi[i] >= TotalSteps) But... I think it's good that you brought up the 32-bit thing, because my...

I tried changing it to both uint32_t and unsigned long, but that didn't change anything. I've managed to get som serial output, and I can see that the values of the array NextBlink_LEDi[] never changes, after it is set in Blink(). I'll read some more on your comments in my other post and see if...

Here is the complete program. The part that I'm having troubles with is only a small part of the code. #include "FastLED.h" /////////// CANDLE PARAMETERS \\\\\\\\\\ // The data-in pin of the NeoPixel // #define WICK_PIN 6 // Any unconnected pin, to try to generate a random seed...

Hey. I have a setup with 5 LEDs. I want these to light up at random intervals, and then fade out. My approach is to have an array (NextBlink_LEDi[5]). It has one value for each LED, indicating the next time it should light up. I have a loop that compares the current time with the value in the...

Hey. I'm trying to debug my code by adding a Serial.println. When I do my code stops running (or so it seems). My setup is a Teensy LC controlling 5 LEDs. I want these LEDs to light up at random intervals. I'm not getting this to work and therefore wanted to output som values to the serial...

Go for it! =) I've added some more modes and parameters to my setup. You can see a demo here: https://youtu.be/NPTSk4bVCTQ I'll gladly answer questions if you have any =)

I'm not actually using my computer for anything except debugging. This: "Serial.begin(9600); //Teensy <=> Computer " is only for sending a line of text to the serial monitor of my computer so I could see what is going on. What I'm using is an app called Touch OSC. It's an app for...

Alright!! I figured it out! :D The problem was in the receiving end of the SLIP packets, on the Teensy. I had 'if(!msgIN.hasError())' inside the loop: 'while(!SLIPSerial.endofPacket())' What happened was that the OSC message was being filled up, and when the address of the message was filled...

I'm really not an expert on protocols and packets, so I'm not 100% sure why SLIP is needed to send packets from the ESP to the Teensy. But I think it's because OSC is an application layer level protocol, and therefore is not made to be sent 'as-is' over a transport medium. SLIP on the other hand...

I've run into another problem instead. When I try to read the value of an OSC message it always comes back as 0. But when I only use the ESP (in other words, when I do not send the packet from the ESP to the Teensy by SLIP), I can read the values. I made a new thread since this is a different...

I have an ESP8266 breakout connected to a Teensy 3.2 The ESP is set up to receive OSC messages over UDP and then send them to the Teensy over serial with SLIP. The teensy is set up to output the received OSC messages to the USB serial that my computer is connected to. When I send an OSC message...

Ok. I'm looking into this as we speak. I've come to the conclusion that there are not actually errors in the OSC messages. The reason I thought so is because I was doing 'if(msgIN.hasError())' while the message was being filled. And until the message is successfully filled this function will...

Hey Adrian. Thanks for the reply. I've been a little busy lately so haven't had time to look more at it. Next week I have more time, so I'll test some more and come back here with a reply then :)

You can find it as part of the OSC library from CNMAT that I'm using: https://github.com/CNMAT/OSC

Hello. I've connected a Huzzah ESP8266 breakout to a Teensy 3.2 through serial. I'm trying to make the ESP receive OSC messages over UDP, and send them over serial (with SLIP serial) to the Teensy, and then decode the OSC message and activate a function. At the moment I've programmed the Teensy...

Yes, the plan is to use a single teensy. I'll see if I manage to reverse engineer the code and get it working :) Thanks for the tip!

I want to wirelessly controll an LED installation I have at home. I'm using a Teensy 3.2 and Octows2811 adapter. I've been looking at the pinout for octo and cc3000 and they seem to use some of the same pins. At first I though, hey no problem, I can just change what pins the cc3000 is using. But...
