Hello everyone. My first post here. So I’ve been enjoying using FastLed for a little bit now on my NodeMCU microcontrollers. However, I wanted to learn to develop for RaspberryPi and was disappointed that FastLED doesn’t support the Pi. I understand their reasoning for not including it. I took it upon myself to “port” FastLED to be able to run on the Raspberry pi, and this is what I have so far: https://github.com/ahettlin/PiLED. It’s not quite a direct port, but it works really well. Right now, it only supports one strand of APA102 (Dotstar) leds on the SPI interface.
Here are two videos of a project that uses the library. It reads midi events and lights up parts of the strip accordingly. I used these two songs as performance benchmarks, so they’re a bit intense
Very impressive! Now, someone (with skillz [not me]) should look at doing this for plain old NeoPixel/WS2812 LEDs. I would be over the moon to beta test.
@Jeremy_Spencer Thank you! Although there is no FastLED for RPi and the WS281x, there are a couple of Python libraries that allow control of WL281x LEDs. They seem to make use of the BCM2835’s PWM module. I haven’t tried any of them, but I will within the week.
