zeitungen / node-rpi-rgb-led-matrix Goto Github PK

So, I am a total nodejs dummy, so you probably roll your eyes.

I tried the following, but it didn't work, presumably because npm did not install the module in a central place. Running npm i as root does also not yield the right result.

Is there anything else I need to do ? I presume I might need to add a path where the actual module is compiled or something, but if so, it might be worthwhile pointing that out in the README.md for idiots like me :)

node-rpi-rgb-led-matrix$ npm i
# ... compiles and stuff

node-rpi-rgb-led-matrix$ cat > testit.js
var LedMatrix = require("node-rpi-rgb-led-matrix");

var matrix = new LedMatrix(16);
matrix.fill(255, 50, 100);
matrix.setPixel(0, 0, 0, 50, 255);
^D

node-rpi-rgb-led-matrix$ sudo nodejs testit.js
module.js:340
    throw err;
          ^

As the title suggests, I'm trying to run a 64 x 64 panel with this library. However, whenever I try to initialize my panel in the constructor and run the code, I receive a message stating that the FrameBuffer is expecting a size that is <= 32.

Is there anywhere I can alter this or is the code incompatible with 64 x 64 panels?

Thanks :)

I have a Raspberry Pi 2 Model B running latest Raspbian, Node.js v4.2.2, and node-gyp v3.2.1

When I try installing node-rpi-rgb-led-matrix via npm I get the following error: https://www.dropbox.com/s/5vbfcsa38wffwwo/Screenshot%202016-01-17%2012.31.16.png?dl=0

Here is the associated npm-debug.log: http://pastebin.com/mBr7AGP2

Afterwards I tried cloning the project in node_modules and building it manually with node-gyp, but it failed again with a different error code. Here's what the output looked like: https://www.dropbox.com/s/jhus8ciayk08kce/Screenshot%202016-01-17%2012.38.21.png?dl=0

Seems like it might be a problem with the project, but it could also be something specific to my environment. Let me know if there's anything I can do to help resolve this!

Pls may you add example for scroll some text or display and image? I'm not really skillful the a help will be more appreciated.
Thanks.

At the moment it's a pain to write text. The external library used by this project supports drawing text with included BDF files.

Hey, I try to use this port but I can't run my test script. When I try to construct the LedMatrix object using

var display = LedMatrix(64, 2, 1);

then I get this back:

node: /home/pi/.node-gyp/8.8.1/include/node/node_object_wrap.h:77: void node::ObjectWrap::Wrap(v8::Local<v8::Object>): Assertion `handle->InternalFieldCount() > 0' failed.

Is this a bug? Thank you!

I haven't actually tested this library yet but as far as I understand, the underlying native library needs to run under root for this to work. Do you run nodejs as root user or is there a way for nodejs to run under an ordinary user and still be able to control the LEDs?

https://www.adafruit.com/product/2345 should it work with this?

Hello,

I was wondering how I would go about adding the GraphicsMagick++ flags from the hzeller makefile into the node makefile. My knowledge is still pretty limited but as I understand it GraphicsMagick++ only gets build when the flags are added. Any advice would be greatly appreciated!

p.s. Love the project!

https://www.npmjs.com/package/node-rpi-rgb-led-matrix
is still tracking the 3 year old version,
I plan on releasing some node modules pulling the new 64x64 enabled library as an npm dependency in the near future; and will be actively maintaining my fork as well.

I could either put my fork up as a new npm package, or could become a maintainer of this version on github/npm if you're up for it.

Is that supported? Thanks!

I'm using node v7.8.0 and the matrix doesn't appear to be lighting up no matter what I use. I've confirmed the size (32x32) and it's clear it's at least trying because it fails without sudo (i.e. requiring permissions, isn't just doing nothing).

I've essentially just been trying this:

> const LedMatrix = require('node-rpi-rgb-led-matrix')
undefined
> const matrix = new LedMatrix(32);
undefined
> matrix.getWidth()
32
> matrix.getHeight()
32
> matrix.fill(255, 50, 100);
undefined
> matrix.setPixel(0, 0, 255, 255, 255)
undefined

The python API works. The demos don't work if I directly go through node_module's into this library's rpi-rgb-led-matrix. Copying/linking to an existing (working) one makes the demos work at that location, but the node library still doesn't function.

No errors, hence why I'm confuzzled.

The error is

Error: /home/pi/node-rpi-rgb-led-matrix/build/Release/node-rpi-rgb-led-matrix.node: undefined symbol: matrix_hardware_mappings

Any ideas?
