Problems such as LEDs being off or being the wrong color.\r\n\r\nI've tested this APA102 strip and the same power source with a Photon microcontroller and it works fine at very low brightness, so the only other variable is the Intel Edison hardware or software.\r\n\r\nI've seen a lot of mentions that the Edison has poor support for SPI (it's emulated), so maybe it's related to that?"}}
