<!-- SC_OFF --><div class=“md”><p>Hi all! I'm working on a project that will involve 25 strips of around 120 LEDs ideally getting data from one microcontroller, which in turn gets some data via ethernet from a computer. I'm wondering what options are available for this number of parallel strips as I haven't quite found an ideal solution yet. </p> <p>Things I've thought about: </p> <ul> <li><p>Pi Pico/rp2040 based chips: not fastled as far as I'm aware, but these can run in principle up to 30-odd strips in parallel. Actually though, only 26 pins are broken out on most Dev boards, which makes sending data to it a bit tricky. </p></li> <li><p>esp32 based boards: as I understand, the esp32 fastled driver currently supports 24 parallel strips (so close!). However, from having a quick look at the i2s info, there's plenty of mention of 32bit writes. I wonder if I could mod the driver for 32 parallel outs? I'd be up for the challenge if it's possible. </p></li> <li><p>teensy 4.x: fastled states 16 parallel outs, which is a bit further off than the esp32, but I <em>really</em> like teensys so you know, might be nice if anyone knows if they could be pushed to 32…</p></li> <li><p>just use two chips: not a terrible route, but makes the physical assembly of this project a bit more complicated for various reasons, adds more points of failure, and I feel like it's possible to only use one board. </p></li> </ul> <p>If anyone's ever managed this, or has any ideas I haven't found, that would be super appreciated.
