Use of RGB LED strips with Foxonix

Hi. It's me again with more questions about a possible lightsaber project. I was wondering if it would be possible to use/program RGB LED strips like the WS2812 with your Foxonix boards - they're individually addressable, would save me a lot of soldering and I could use any color I wanted. Anybody tried this?

Regards.

Hi Lorne:

I looked into this a bit, and it doesn't look like we'd be able to get the WS2812-based LED strips to work because of the timing requirements for the data signal. Without getting into it too much, I don't think we can get the pulse widths narrow enough because the minimum cycle time of the microcontroller is 4 uSec.

However, it DOES look like an APA102C-based LED strip could be made to work. This would require two output pins from the Project Board: one for LED data and one for the clock. I don't know what the time frame for your project looks like, but we can get some of these LEDs on order and work on a routine for writing to them, probably within the next few weeks. If you want to start working on this on you're own we're here to help you, for sure.

Hi. Thanks for your reply. I will do some research into the APA102C-based LED strip. As for the time-line - I'm not in any real rush. Even if you took a few weeks or even a month or 2, that would be fine.

If you find any results, let me know. Much appreciated.
