Adafruit_GFX-compatible library for NeoPixel grids

Adafruit_NeoMatrix. Whoa.

Adafruit_GFX-compatible library for NeoPixel matrices and grids. Controls single and tiled NeoPixel displays such as the Adafruit NeoPixel Shield or grids assembled from Adafruit 60 LED/meter Digital LED strip. Requires Adafruit_NeoPixel and Adafruit_GFX libraries.

After downloading, rename folder to 'Adafruit_NeoMatrix' and install in Arduino Libraries folder. Restart Arduino IDE, then open File->Sketchbook->Library->Adafruit_NeoMatrix->matrixtest sketch.

adafruit_neomatrix's Issues

neomatrix in ESP32-S2 am having difficulty

I am building a NEOPIXEL panel (120x15 eventually, but now it is 120x8). I also have two 16x16 panels to test with. The small panels seem to work properly using an Arduino Uno, but it does not have enough memory for the big panel. I have two programs working using the ESP32-S2, but noticed that the program that uses a single panel (and it works!) is coded wrong. It is coded for the starting point to be NEO_MATRIX_TOP + NEO_MATRIX_LEFT, but the panel is wired for top right.

• Arduino board: ESP32-S2 (Saola-1)

• Arduino IDE version (found in Arduino -> About Arduino menu): 2.0.0-rc3

}
int x = matrix.width();
int pass = 0;

neomatrix could display RGB pixmaps given support in adafruit gfx

which thankfully I wrote over 2 years ago :)
(but it's not merged yet)

Hopefully it'll be included eventually, but in the meantime if anyone is looking at doing this, they can look at this PR and use the code here:

Led Color / ws2812b

Hi,

I've got some issue with color functions.
The result is not the same ... and I don't know why.
(I try to play with brightness | color minimize light with it).

But cannot find the same color. (probably the 24bit and 32bit)
(What is the right way to deal with color with my ws2812b matrix)

 Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(32, 8, 3,
  NEO_MATRIX_TOP    + NEO_MATRIX_LEFT +  NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG ,     /// ZIGZAG for matrix display 
  NEO_RGB            + NEO_KHZ800);
  matrix.setPixelColor(1,0xff7e00);
  matrix.drawPixel(6,7,matrix.Color(0xff,0x7e,00));
  matrix.show();

Thanks.

mixed line and Matrix

Question: I have 32 pixels in a row and then on the same command pin, a matrix (32x4)

Is it possible to drive the matrix using this library giving an "offset"?

Serial.begin() kills neomatrix

I used the matrixtext example for my neopixel array.
I wanted to add builtin serial port to change the message. But, when I add the (Serial.begin();) line array doesn't update.
I used pin 13 on my Arduino Nano, to use the LED an activity light. But there is no activity when serial.begin() is used.
I comment out Serial.begin and matrixtest works, un-comment it, and it stops.

I'm thinking it may be a Timer issue... Like maybe, neomatix library uses same timer as serial port... (I don't know, just guessing)

Thank you for opening an issue on an Adafruit Arduino library repository. To
improve the speed of resolution please review the following guidelines and
common troubleshooting steps below before creating the issue:

• Do not use GitHub issues for troubleshooting projects and issues. Instead use
  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
  something isn't working as expected. In many cases the problem is a common issue
  that you will more quickly receive help from the forum community. GitHub issues
  are meant for known defects in the code. If you don't know if there is a defect
  in the code then start with troubleshooting on the forum first.

• If following a tutorial or guide be sure you didn't miss a step. Carefully
  check all of the steps and commands to run have been followed. Consult the
  forum if you're unsure or have questions about steps in a guide/tutorial.

• For Arduino projects check these very common issues to ensure they don't apply:

  • For uploading sketches or communicating with the board make sure you're using
    a USB data cable and not a USB charge-only cable. It is sometimes
    very hard to tell the difference between a data and charge cable! Try using the
    cable with other devices or swapping to another cable to confirm it is not
    the problem.

  • Be sure you are supplying adequate power to the board. Check the specs of
    your board and plug in an external power supply. In many cases just
    plugging a board into your computer is not enough to power it and other
    peripherals.

  • Double check all soldering joints and connections. Flakey connections
    cause many mysterious problems. See the guide to excellent soldering for examples of good solder joints.

  • Ensure you are using an official Arduino or Adafruit board. We can't
    guarantee a clone board will have the same functionality and work as expected
    with this code and don't support them.

If you're sure this issue is a defect in the code and checked the steps above
please fill in the following fields to provide enough troubleshooting information.
You may delete the guideline and text above to just leave the following details:

Could you make this matrix code usable for other sized matrices?

three 16*16 ws2812b matrix to create a 48*16 matrix

Hello,

since i want to create a 48*16 matrix made of three 16*16 ws2812b matrix i am looking for a library that let me do that. I am on Arduino nano and every other library (FastLed,...) are to much RAM consuming. Since Neo_Matrix is no consuming that much RAM is it possible to define some thing like:

Adafruit_NeoMatrix matrix1 = Adafruit_NeoMatrix(48,16,PIN,
  NEO_MATRIX_BOTTOM + NEO_MATRIX_RIGHT +
  NEO_MATRIX_COLUMNS + NEO_MATRIX_ZIGZAG,
  NEO_GRB + NEO_KHZ800);

because for now with neo_matrix we are limited to 32*16 matrix

keywords.txt missing?

I've been trying to tinker with one of your snazzy NeoMatrix Shields (5X8) for a couple of days now. After reinstalling Arduino (updated to ver 1.6.13) I've installed the libraries for NeoMatrix, NeoPixel, and GFX — all the newest iterations. Upon testing out the matrixtext code there seems to be a processing problem of sorts. While NeoPixel library turns orange, NeoMatrix and GFX do not. Thus the NeoMatrix object doesn't seem to respond and the code doesn't run on the matrix shield (the "HOWDY" message doesn't show up).

The Pixel library folder included a keywords.txt file. Matrix and GFX appear to be missing a similar document. What should I do to fix this? I was really looking forward to playing around with the matrix but can't do much at the moment.

initialisation of member 'passThruFlag' forbidden

The NeoMatrix library can't be compiled any more. The following error is thrown when I try to compile my project. Or is it just a setting that I have to give to the compiler?

/home/fgierlinger/Arduino/libraries/Adafruit_NeoMatrix/Adafruit_NeoMatrix.h:101: error: ISO C++ forbids initialization of member ‘passThruFlag’
/home/fgierlinger/Arduino/libraries/Adafruit_NeoMatrix/Adafruit_NeoMatrix.h:101: error: making ‘passThruFlag’ static
/home/fgierlinger/Arduino/libraries/Adafruit_NeoMatrix/Adafruit_NeoMatrix.h:101: error: ISO C++ forbids in-class initialization of non-const static member ‘passThruFlag’

I'm using Eclipse Mars (4.5.0) with the Arduino IDE plugin for Eclipse and Arduino 1.5.2.

NeoMatrix is awesome but does not support FastLED supported hardware

FastLED supports more than just Neopixels, and supports Neopixels on hardware that Adafruit::Neopixel does not work well, or possibly at all.

Merge features from ledtable library

I am a developer of the ledtable library.
There are features which can be merged into this library:

• 5px font with variable width
• allowing programming and viewing though a virtual led-matrix as a computer program
• html color names?
• examples

What are your thoughts?

Individually controlled tiled sub-matrices?

Is it possible to make a tiled matrix where each of the sub matrices are individually controlled by their own digital pin?

I am using the TiM board, which can be controlled with 8 output pins - one for each row.

Any easy way to change font size?

Tiled example wiring?

I'm working on a LED-wall project using neopixels stripes. The setup is roughly 36 columns of 120 LEDs.

I can't understand the difference between the tiled matrix example & the non-tiled one. They both seem to use a single PIN, so it looks like both have chained PWM? What would be the maximum number of LED using a single PWM line?

Was thinking of using two servo-shields to manage 18 tiles (120*2 led, a 4m strip cut in half & put 180° down with their own power supply). Would this be doable with this library? How would I handle the 18 separate PWMs?

Thanks a lot!

NeoMatrix text wobbling, its moving up and down

I'm running the matrixtest example on 10x10 ws2811 matrix. I have just changed the height and width while declaring the matrix, everything else is original code. I have double checked the wiring.

The problem is the text is jumping up and and down along with moving left. I have drawn a vertical line moving left and the line is similarly jumping up and down while moving towards left. I have tried on both Arduino Uno and Esp8266, still no luck. I have reinstalled all the libraries, still issue persists. Any help is appreciated !
