I’m trying to interact with a single RGB LED from a WS2812 strip using the Nano’s GPIO. I was able to do it on a raspberry pi using this library GitHub - jgarff/rpi_ws281x: Userspace Raspberry Pi PWM library for WS281X LEDs, but it seems there’s no easy way of doing it on the Nano.
Does anyone know of a RGB LED type that we can interact with the Nano preferrably using the python GPIO library? GitHub - NVIDIA/jetson-gpio: A Python library that enables the use of Jetson's GPIOs
Thank you.
The easiest option would be to port parts of the library from GitHub - jgarff/rpi_ws281x: Userspace Raspberry Pi PWM library for WS281X LEDs that is using the SPI interface as most of the code is generic. The hardest part would be stripping out the rpi specific code. You can use the dtb file I posted in this thread to enable SPI on the nano.
Thanks, but that will be too hard for my current deadline.
Instead I’m going to use something like:

It is possible to control ws2813 led strips. See seeedstudio’s grove devices: Play Grove with All-New Python Libraries - #Nvidia Jetson Nano #Coral dev board - Latest Open Tech From Seeed
