I am programming many things with 8 bit Arduinos. Now i want to change to the esp8266 chips.
I search the web about the FastLED library with SmartMatrix. With the libraries i found only the simple sketches work like strandtest and so. Text scrolling i never found. Also the DMAChannel.h i don't found. Only for teensy.
Can someone help me with a working link for the libraries?

Thank you
Bye

I tried various libraries for the esp. The FastLED 3.1.3, NeoPixelbus master, AdafruitNeoPixel.....
The libraries works, but i want also have scrolling text from right to left.
When i try SmartMatrix3, the compiler search DMAChannel.h and kinetis.h. I install the libraries from guthub, but i think this libraries are only for teensy. I have no idea what change are necessary.
The "easy" code like cylon and so on works, matrix not
Have anyone a idea?

Thanks
