Neopixel LED strip with a HiFive1

Here’s a github repo where I drive a Neopixel LED strip using my HiFive1 board.

It was a learning project for me – learn about RISC-V/HiFive1 and about Neopixels.

Cool eval board, love it.

Hope folks find the LEDs interesting.

I randomly grabbed a neopixel string when they went on sale for a day on amazon.

I’ll have to give this a try.

Thank you very much for sharing this.


I just updated the code Makefile to work with the current freedom-e-sdk version. The original work was based on an older SDK version and no longer worked. It should be good now.

Let me know if you have any problems.


For whom it might be interested we ported the Adafruit_NeoPixel library to HiFive1 for Arduino here
