- Fri Dec 18, 2015 9:16 pm #36760 Ok. Here it is. Just uploaded a new version tonight.

Neo Pixels are supported now!!!

Will only work on pin 15, D8 for node mcu boards. I was unable to set it so that this is changeable.

You can now write to individual pixels up to 255 of them.

the function is

Code: Select allneo({LED NO},{R},{G},{B})

So to make the 5th led inn the string green you would use.

Code: Select allneo(5,0,255,0)

I plan on adding some more function for setting the whole strip color and maybe some simple animations as the interpreter is a bit slow for doing this in basic.


I tested my strip with this code. It will sweep down the strip turning one pixel on at a time.

Code: Select allfor x = 1 to 25
y = x - 1
neo(y,0,0,0)
neo(x,0,255,0)
next x
end

A great Christmas present from you !!!!

Now we can set colours in a ledstrip using the sliders from anywhere in the world........

A question though.
Why isn't it going to work with an ESP8266-01. Would be nice. It has only two I/O ports and it would be great to adress tons of neopixels with such a tiny processor.

And........
This definitely opens up the need for an 2 dimensional array function.

I know, I am asking too much.

Nevertheless I will start experimenting with this and have some ideas already in mind.

Thanks again.

in the NEO command can R G and B be variables or can they only be integers??
would it be possible to create a version of the OS for the -01 module that would support the neo pixels on either of the two pins available on the -01 model??

Or have the OS determine the version of ESP module it is loaded on and re-assign pin 15 (D8) to one of the pins available on the -01 module?


thanks for all you are doing
