I have added a bit more information to my request for some advice. This sketch works on esp8266 and fastled but stores all 137 patterns in RAM: https://github.com/djnamaste/POV-ESP8266-stored-in-ROM I want to take advantage of the flash space on the esp and add more patterns and functions...

https://github.com/djnamaste/esp8266-supernova-attempt I am working on porting Adafruit's POV code to work on esp8266. Using NodeMCU this sketch works when using graphicsesp.h but it saves patterns in the working memory, not in flash. Changing the pattern file to graphics.h does not work but I...

Hello, I have a teensy 3.5 that will only work if pressure is applied on the board after a hard fall/impact to the board. I am wondering if I can resolder by hot plate method with the 3.5? Any other tips?

Hi, I am wondering if anyone can help get Adafruit's pov code to work on ESP8266. I believe the problem is that PROGMEM is handled differently in ESP chips. The code compiles but does not work. I know it is wired correctly as I have tested with a simple led chase code. The POV code in this...

This is a test pattern 32 pixels tall that should repeat down to the length of the led strand of 160 leds. The code below is the graphics.h // Don't edit this file! It's software-generated. // See convert.py script instead. #define PALETTE1 0 #define PALETTE4 1 #define PALETTE8 2 #define...

Hi, I am trying to repeat images down the row of Leds using the Supernova poi code from Adafruit using Teensy 3.2. The code below will display a 32 pixel image multiple times down the row. The problem is there is a flash between frames after the 32nd pixel. It is also displaying slower than the...

I'm kind of following you but don't quite understand some of it. I've found in other discussions that say you cant generate and send new data using send.raw as it requires a defined value stored in memory. So if I want to generate a random number between 0-200 by one teensy and to receive that...

Okay, this code is sending ir data from one teensy to the other teensy. Now instead of a NEC code, I want to send a random number generated from the sending board to the receiving board so they each get the same random number. How can you send a data value over IR? #include <IRremote.h>...

Hello, using Ken Shirriff's irremote library, I want to send data using a remote to one teensy and have it relay that same code to another teensy. So one relays to the other the same value. I have a sketch that is set up to send and receive the data The IR emitter is connected to pin 5 on...

Did you get the original poisonic sketch working? It seems the best way to do what you want is to have the hall sensor trigger the start of the image display and then adjust the time of the image display to fit.

Is this the same for 3.2? I usually would trim the edges of 3.0 and 3.1 and it would still work. I trimmed the 3.2 edge and it will not work. I can't figure out why because I don't see anything related to the power or ground on the pins that would stop it from working.

Yes I saw that. Anyway, the question here is can I get this board working again? I trimmed down the pins on one side and thought it would not cause issues for the processor. it has worked before but I must have trimmed too much and cut into a essential wire that powers it. I looked at the...

Hello I am working on making a hula hoop. Previously I have trimmed down the edges of the teensy 3.2 by cutting the pins off from pin 13 and up and just using the pins on the opposite side. It has worked for me in the past and this time around with the board I purchased a couple weeks ago, it...

Yes that works. Interesting how you are using color index to create the strobes. Is there any more examples like this?

This piece of the code is how ive done things previously. It repeats the strobe effect until 50 is reached, then it goes to the next strobe or rainbow chase. I want to make it do the color wipes until 5 seconds pass, then move to the next strobe color combinations. for (j = 0; j < 50; j++) {...

Paul, I am creating a bunch of sequences of color wipes, rainbow chases, etc. I want to do each sequence for 5 seconds which strobes really fast. For example, red then blue colorwipe repeated for 5 seconds, then on to green/purple colorwipes for 5 seconds. I have used for loops in the past...

Hello I am using apa102 and ws2812 leds for some projects using adafruit's neopixel and dotstar libraries. I want to do a colorwipe of one color then a second color to get strobe effects. A for loop works but every time I change the led strand length I have to change the for loop duration to...

Also, when I send data from the clock output on the led strip closest to the teensy it makes the leds work better on both sides. It seems the clock signal, which is a square pulse I think, is going down the wire due to less resistance and the clock signal down the shorter line is weakened or...

Hi I am wondering if you can tell me what is going on and help diagnose a problem. I am making a staff with a single teensy 3.2 and 32 apa102 leds. There is a 4 foot section between staff led ends. The teensy is on one end and connects with about two inches of wire to the led strip on that...

Hi I am wondering if you can help with something. I have been playing with the adafruit palette poi and want to again display the same image multiple times down the strip. So what you helped with before mortonkompf. The solution was to duplicate the statement of the array with a different start...

How would it be coded? The code above works and I did get a rainbow with some blinking lights but it did not come out as an image. I haven't worked on it since then. The ability to change colors of a bit mask would make it super cool.

I modified it identifying a few mistakes. Now it works and displays images but they are all red. http://pastebin.com/HEEK0q1c

Hi, I have spent a while trimming down the adafruit poi version and have it working on a teensylc with just the pov code running, not all the other remote and battery monitoring stuff. It works with the adafruit library and I have gone through and changed the strip.show to FastLED.show and I am...

Hello I would like to create a way to convert simple images into a bitmask and send a fastled rainbow function or other colors through the bitmask. The code below is a pov image of a skull and crossbones. It is pretty low resolution but the example works but only displays blue where the color...

What do you mean from Adafruit? Are you running the Adafruit pov code and not mortonkopfs? There is a debounce delay in the Adafruit stuff I think maybe that is what I need to add.

How did you do the IR? I cant get it to respond when spinning.

Looking at the pictures it seems that you have data connected to pin 1 and clock on pin 2. In the code it says data pin 2 clock pin 3. I am not sure by the pictures but it looks like you did not account for pin 0 as the first pin next to ground, pin one, pin 2. Edit, I looked again and I cant...

I checked the code and it is working for me. I would suggest a simple circuit with the leds connected to the board without all the battery circuit and everything and trace it back. I dont see what is wrong. If you are using APA102 leds it looks like it should work. I am not sure about...

Thank you that works. I was thinking of having it repeat after each length is reached but I realized on a hula hoop with various led length strips it would leave uneven ending images so I mapped out starting points by dividing the hoop up into 8 points.

I went through the code and changed some things so its easier to understand what is going on. http://pastebin.com/pmycpvb1 Still not able to get the image to repeat.

Found this code mixed with the POV code creates two images, even separate images if you like. The code here is a heart and a mushroom, one over the other. Im still running into an issue with it though. It cycles through correctly for about 10 seconds, then it switches the arrangement to the...

The code below is my attempt. It is displaying a heart in the first 16 pixels and below that there is the same colors blinking but out of order. It is a 16x16 file. I made a new space for the pixel length to be defined. Not sure what I am doing wrong. #include "FastLED.h" #define NUM_LEDS...

Yes repeating down the line so multiple images. I think the NUM_LEDS needs to be changed to a different variable that can be set to the image height. I'm pretty sure that is what I did wrong. Right now I have one image on the top of the strip and the bottom image is all scattered like what...

I would like to use smaller images and repeat them down the row of LEDS. Im sure there is a way to do this but how? This works on the top image but the image below is a blinking mess. How do I change it so it displays images down the line? void PoiSonic(unsigned long time, const unsigned...

Hello I found a way to perform POV - Persistence Of Vision images using the Adafruit Neopixel library with a bit of code I modified. The code runs on Teensy lc but on teensy 2.0 the dynamic memory is something like 95% and it will not run the code. The teensy will run FastLED POV code fine but I...

I did not enter the right slice number. Now that is corrected its working fine just wish there were more space. When using a SD card shield, does the code change much? I have some shields and did get teensy communicating with the card. I would like to make it so the card can have images...

Got it working now. Im using teensy lc and it is displaying images like it should. How many images can you fit on teensy 3? I have 3 images, 60x60 and thats all I can fit. I will probably cut it down to 30 leds but would like more that a dozen images if possible.

I tried the code on a teensy lc and it compiled and uploaded but I just got white leds and the bottom half kind of strobing but not an image. I've got the Adafruit POV sketches running okay so it is wired up okay. Not sure why it's not displaying images. Is there any other compilations I can...

Can anyone point me to basic POV in Arduino? I am using the Teensy 3.0 and ws2811 and have the system set up and running. I would like to get some basic POV patterns running at random. I have seen the tutorials where a PIC controller is used with LED's on individual pins but the LED strips...
