Hi all,

 

I am trying to work with WS2812B RGB LED(GPIO Controlled) + SAML21 in Atmel studio.

 

Board: SAML21 Xplained Pro

Sensor: WS2812B RGB LED

IDE: Atmel studio

 

Looking for WS2812B Library which supports ATMEL Studio.  I could not find any reference library online.

 

How do I do this? If anyone can help, that would be great.

 

I have tried to port Arduino library below libraries. But no outcome.

* https://github.com/kitesurfer140...

 

Thanks in Advance.

Errr ... that's not a sensor

Search the AVR section of the forum - there's loads of discussion there.

 

Also google:  there are lots of people who have done this in various ways - and documented it online.

You realise that Atmel Microchip Studio can import an Arduino "sketch" ... ?

EDIT

 

WS2812B Library which supports ATMEL Studio

The important thing is not Atmel Microchip Studio - that's just a fancy GUI.

 

The important things are:

  1. That the code is either for Cortex-M, or is independent of the CPU architecture
  2. That the code is compatible with the tooolchain used - ie, GCC.

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

Hi awneil,

 

I was familiar with Atmel studio supports Arduino sketches. But I want to use ATMEL Software Framework, not Arduino code.

 

I am looking something in these lines: https://github.com/benlhy/WS2812... for SAML21 Xplained Pro Board.

Once it has been imported, it becomes just a standard MS project - totally independent of your Arduino installation & IDE.

 

So you can work from there as you wish.

So use that, then?

Getting timing issues. Don't know how to solve that.

You'll have to analyse the code:

  1. How is it trying to achieve the correct timings?
  2. Where is that going wrong?
  3. Fix that!

 

You could raise an Issue in GitHub: https://github.com/benlhy/WS2812b-SAMD10/issues/1

 

EDIT

 

The code provides a set of links - have you studied them to understand what's going on?

The implementation provided in the GitHub reference is matching with the functionality of WS2812b mentioned in the datasheet.

 

So I am re-using the same code.  Changed the SPI Defintions as per the SAML21. But RGB LED is not working.
