Driving a WS2812 LED strip
#1
Hi everyone,
anyone tried to drive a LED strip with the Tinkerboard?
The protocol describing the bit is quite strange and quick, maybe any C library yet exists?

I found a lot of example for RPi but none for Tinker ..

Thanks

You might try to use those for RPi. BTW do you have some link to compare them whether they're worth to use.
Light blue words might be a link. Have you try to click on them? Big Grin

I tried with rpi_ws281x https://github.com/jgarff/rpi_ws281x, converting the project for Tinkerboard.
But after a while I discovered that it uses DMAs and a device called "/dev/vcio"  I do not know.. Huh

I read a bit from that source. They really work to allocate a set of memory for the program. I think you might write to them and ask whether they have the capabilities to port the code to TB.
