Hi FriendlyArm,
I bought NanoPi-M3 from FriendlyArm and bought Neopixel(WS2812) from Adafruit.
Adafruit provides Neopixel(WS2812) driver source code for RassberryPi.
I have no RaspberryPi and need to port Adafruit's WS2812 driver into
NanoPi-M3.
You can get the source codes from here..
git clone https://github.com/jgarff/rpi_ws281x.git
and, you can find how to use this code on RaspberryPi =>
https://learn.adafruit.com/neopixels-on ... i/software
I installed rpi_ws281x.git on NanoPi-M3(Debian) and changed the PIO number
in "examples/strandtest.py" (I connected Pin33(GPIOC13/PWM1 with Neopixel
Din and put the PIO number as 77) and run but faced "DMA error: b6e6f558".
I think it is due to the different DMA address & offset and need to know
about NanoPi-M3 SoC. but, I don't have any data of it..
so, I need your help for this project..
please see the source codes, and let me know what I have to fix for Nano-pi-M3.
it is very important for me, and need your help asap..
thanks..
