Atmega1284p problems with pinouts and digital ports

Other Hardware 3rd Party Boards

Hello,

I'm using Atmega1284p with Arduino.
Right now im using mighty-1284p with v1.6.3 maniacbug bootloader. Also i tested with avr-developers bootloader.

The following image is my current settings for bootloader and programming:

Pinout i use:

                     +---\/---+
           (D 0) PB0 1|        |40 PA0 (AI 0 / D24)
           (D 1) PB1 2|        |39 PA1 (AI 1 / D25)
      INT2 (D 2) PB2 3|        |38 PA2 (AI 2 / D26)
       PWM (D 3) PB3 4|        |37 PA3 (AI 3 / D27)

My problem:
I use D0 as digitalpin for FastLED library data pin, and it won't work or light any LED. I used a multimeter to measure the voltage on pin and i get 1.3V... Thats one reason why pin don't work to interface the fastled. Also D0 is a Timer still the datasheet says that can be used as digital pin, but i can't get it to work.

After try many things (on software and hardware) i can't get it to work. I can move this hardware to other atmega pin but that will require redo some paths and resolder.

Anyone can give me some tips or solutions?
Note: Its not a code bug or error since it works well with a arduino Nano (Using nano pinout). All other stuff on normal pins are working correctly.
I'm using a 5v Power Supply with 5A, its not a power fault.

Pictures about what im doing:

LEDs working with Nano with same code but different pin for data:

I use D0 as digitalpin for FastLED library data pin

I'm confused. I don't see any neopixel-style LEDs in your photos...

Yes, you can't see it on the photo because they are a separated module that can be attached in the 3 pinholes near the PIR. You can see it on fritzing image, its located where it says Clock Protection with a capacitor.
On that image i dont have the LEDs connected. The images are only to understand my connections. That connections are the same i use on nano in a separated board and it works. As i said its something with D0 pin. 1.3V don't seens correct.

EDIT: i have modified the first post with the LED image

I have fixed the problem...
FastLED library maybe don't like atmega1284p or pin0, none of the samples worked.
After try with neopixel it work at the first shot!

Using neopixel now.

Thanks
