Using NeoPixel led strip with Arduino giga R1

Post by Zawi »

Hi,
I am using a WS2812 led strip(https://thepihut.com/products/flexible- ... 9774879939) and have been successfully using it with an Arduino Uno. I recently upgraded to the arduino giga r1 wifi because my project needs advanced capabilities.

The fast_LED library doesn't support the giga r1 but i was wondering if i could edit the library for neopixel to support the giga r1? When i compile an example program from neopixel there are no errors but the led's on the light strip don't turn on. (I have checked that the data pin is set correctly) I am also experienced in coding but new to editing libraries

It looks like the Giga R1 uses an STM32 microcontroller. The NeoPixel library supports that platform in general:

https://github.com/adafruit/Adafruit_Ne ... .cpp#L2573

but it may not have code for the specific version in the Giga. Take a look at the existing code and see if you can modify it to do what you need.

On the positive side, it shouldn't be hard to get 800kHz signal timing with a microcontroller that runs above 100MHz.
