Edit: I can confirm that the Teensy 3.2 works great with the SparkFun FM Tuner Break out and FastLED. Super thrilled to get this project back on track and will post some pics/vids when it is completed.
Will a Teensy 3.2 work with FastLED and be able to handle interrupts with an FM Tuner that uses I2C?
I have an Uno setup right now and just as I expected, when the tuner gets initialized the LEDs quit working. I’m hoping the Teensy will solve the problem.
I assume you’re using three wire LEDs, like WS2812? I haven’t used an I2C FM tuner library, but I have used IR which uses interrupts with Teensy 3.2 and WS2812. As long as the interrupts are fast (don’t take more than 5µs to run), it will likely work: https://github.com/FastLED/FastLED/wiki/Interrupt-problems
@Jason_Coon Yeah ws2812. This is a first for me with the FM tuner and also a relay. I’m helping my father in-law build a clock radio with an old CRT tube. Everything is working with an uno other than the FM tuner. I have plenty of spare teensy so I’m hoping it will fix the problems. If not, we use 2 boards and I figure out how to make them talk to each other.
Or find some single apa102s to solder together.
We are only using 3 LEDs total.
