Hi! FastLED developer/maintainer here - I’m currently going on a tear getting FastLED ported to a variety of new platforms, and someone recommended the Electric Imp to me as a possible platform. Unfortunately, all the docs that I’ve found so far simply have a generic reference of “cortex-M3” as the arm core in the chip. In order to port FastLED I need to actually know what the actual chip is, and the reason for this is that every arm manufacturer (Freescale, Atmel, STM, Nordic, NXP, etc…) does their low level device access (GPIO, SPI hardware, etc…) wildly differently.
If that information is obtainable, I can look into seeing about doing a port.
