In JPearman’s demo for the AddrLeds he sets the led count to 60. In Sylib the limit is 64. I have a strand of 58 LEDs that only pull ~1A of the 2A Smartport limit, so I’m wondering if its just a software SDK limitation or if it’s a limitation of the Hardware, or if it’s an arbitrary limit to prevent overloading the brain.

The addressable LED are handled by a combination of code in vexos and on the 3wire expander. vexos has to send information about each LED to the 3wire expander, that has to maintain buffers to be able to send the color (3 bytes) to each LED in the strip. When considering memory needs, communication time and other factors, I felt that 64 LED was a reasonable number per port.

Ah that makes sense thanks.
