Hi everyone!

I’m having troubles compiling the example ParallelOutputDemo for an Aduino Due . Fastled lib is fresh pulled and installed, IDE is 1.6.12

Grab the most recent version from github, I just put a fix in for this.

3

Awesome! I’ll check it out asap. Thanks so much

4

Problem solved. Thanks again.

5

Sorry, I spoke to soon. While the code compiles now, it doesn’t turn any led on… like there’s no output at all on the pins. Changing the addLeds setup to non-parallel and everything lights up (same hardware, same pins). Any ideas or debug I could turn on to find out what’s going on?

6

Not offhand - other than trying to set the lane count to 8 (make sure to provide enough led data for that!) - just in case there’s something that isn’t handling fewer lanes welll. It’s been a while since I’ve tried the due parallel code, so it’s possible something is off in there.

7

8 lanes confirmed working. Thanks again!

8

I just checked in a fix that should help the parallel output when there’s less than 8 channels - but don’t have an easy setup to test it here (but looking at the code it was glaringly obvious where I had forgotten to make a set of changes when I switched over the clock that I was using for timing on the due). - master@HEAD in the main repo.

9

The project is wired with 8 channels and working great so far. I will test with less tomorrow and let you know.

10

Tested and less than 8 channels works fine now too. If you need someone in the future to test the library with a due and parallel output, just let me know. I’m happy to help :slight_smile:

Hi, are you using any level changer at the output of your arduino DUE ?, I am thinking of using that platform for the low cost and easy to acquire in my country.

12

Yes, 2 4x level changers to bring the signal to 5V. I still need to work on fixing the RFI a 8x1 meter cable generates. There are no stuck leds or crosstalk. just lots of noise on the radio. I’ll just shorten them …

13

Could you show me your connection scheme of your matrix ?, I am still learning about how to make this type of arrangements with output in parallel and behave as a single matrix. Obtaining the benefit of greater data writing speed on the output

Basically like this with 8 data lines, not 4… http://imgur.com/a/SST4S
