For W2812B no any library is working with ATMEGA128 (i am using mega core arduino)

BHARGAV_1990 · July 2, 2022, 2:46pm

Hello...

I want to use W2812B led in my project. my microcontroller is ATMEGA128.
i am using arduino for code development. i tried all available library (FastLED, W2812FX, etc...) to operate W2812B LED but in arduino compiler i am getting error below.

exit status 1
Error compiling for board ATmega128.

Please help which library should i use to operate W2812B led using ATMEGA128 (mega core arduino).

Enable verbose messages option in the compiler and post the full text of the error message. Because of the protocol of these LEDs, the libraries use specific commands and work directly with the microcontroller ports, which means that you may not find a working library for the ATmega128.

Error compiling for board ATmega128.

i used FastLED library for this compilations.

flashko · July 3, 2022, 12:19pm

It looks like this library will not work with this microcontroller. I can recommend another one. For me, the sample program for WS2812 from the FAB_LED library compiles normally without an error message when the ATmega128 chip is selected.

Good luck.

Hii..

I have try library you suggested.

using FAB_LED compilation error solved. it compiled program perfectly but on real hardware only White Color is On.

i used sample program provided by Library. Code is as below.


#include <FAB_LED.h>

// How many pixels to control
const uint8_t numPixels = 28;

// How bright the LEDs will be (max 255)
const uint8_t maxBrightness = 16;

// The pixel array to display
grb  pixels[numPixels] = {};

    pixels[i].b = b;
  }
}

  // Write the pixel array green
  updateColors(0, maxBrightness, 0);
  // Display the pixels on the LED strip
  strip.sendPixels(numPixels, pixels);

Some smart LEDs light in white when no data has been received. Check that you have connected correctly. Check that the selected pin matches the port and number in the program. Check if there is a signal on the pin with an oscilloscope. Why did you choose exactly port F, pin 0? The datasheet says that if the ATmega128 is programmed in compatibility mode like the ATmega103, the port F pins work as digital inputs only. Try another pin and port.

BHARGAV_1990 · July 5, 2022, 5:06am

Hii Flashko..

I have disabled Atmega103 compatible mode from fuse bit setting.

I choose exact pin F,0 because my PCB is already designed. however I also tried with other port and pin. result is not change.

when i check output in simulator i am getting digital pulses like below but in hardware no output.

In oscilloscope on each pin I got no any signal. when i simply on and off pin i am getting square wave of 0 and 1.

Hello flashko...

I found solution of problem.

I was running my ATMEGA128 on 8 MHz internal clock frequency and when I read full library document detail than I come to know that this library works on 8MHz and higher frequency and they didn't have tested on 8MHz as they mentioned.

So I change my frequency to 16MHz and Tested it works perfectly.

By the way thanks for your support.
