Hi Max… I’m wondering what changes I would need to make to use timer1 for the dmx receive code ?

I’ve got a LEDStrip demo working, but it uses timer2 for PWM, *adafruit RGB led strip*

Thanks

Hi, very interesting project. I was just wondering whether this could be used so that I could plug in my DMX output from my lighting desk into the input of the shield and the output of the shield to my demultiplexer (My school doesnt own any “DMX” lighting fixtures). This way, I could control many interesting things from one simple input from the desk (Lets say a flash button being pushed) could trigger all manner of interesting chases and scenes, co-ordinated to the second.
Thanks,
Michael.

Hi Jason,
I think the holes would be extra in this case– the board as I laid it out has holes for jumper wires on the top (single sided board), while the cutedigi board is double sided. I’d be interested to know how the build goes with their product, be sure to post back with your experience (I’m not affiliated with them in any way).

Someone mentioned that the code as written does not work with the Uno, I don’t have one to test with myself. But the processor is the same so I would think that adapting the code would be fairly straightforward, if any adaptation was needed at all. Again, I would be interested to know what you experience is.

Best of luck!

First, my thanks to Mr. Pierson for developing this board and software. I’m really just a carpenter working as a TD for a non-profit theatre in Washington, DC, and I’m just trying to put some simple DMX effects together.

I’ve been successful with sensors, wireless, wav files and motors thanks to shields/tutorials from another site- so I’m not totally helpless (though if this thing were made out of wood I’d be more comfortable!).

I bought 2 PCBs from cutedigi, and the parts from the list, but the cutedigi boards have some extra holes (above and below the Max485 for example, and just above the reset button). Are these holes to be left open, or are they for optional/added components?

If anyone has a picture of a functional, assembled cutedigi board, I guess that’d be enough, too.

For the record, I am using the Arduino Uno.

Thanks!

Hey!

Do you have any dmx board to sell? Even without the parts..I’d buy it, please send me an e-mail.

Thanks

Recently buy parts to make DMX shield from CuteDigi, three questions:

I have DMX 3 pin LED bars, its compatible?
How to connect from 3 to 5 pin and viceversa?
Need to make some changes in code?

Thanks.

Hey!

Just want to say thanks, i’ve been loosing my patience trying to do it myself :)

Works great for me and my project: http://translate.google.com/translate?hl=sl&sl=sl&tl=en&u=http://www.gzt-project.si/%3Fpage_id%3D148 (a bit clumsy google translation…)

Hi,

I build DMX I/O shield. I managed to change dmx address, but I don’t get dmx signal. I am sending with other arduino with DMX shield. It sends fading values for every channel. But I still don’t receive nothing. DMX shield is tested with dmx tester and it is working.

Does DMX-512 I/O Shield works with Duemilanove328?
