Hi Guys,
I have written a little bit of code to send DMX-512 using the UART of the photon. I’ve shared the library called “SimpleDmx”, so that other particle users can use it.
It’s also available on Github: https://github.com/ahanak/particle-simple-dmx
I know the topic is old, but I found the topic while searching for a way to send DMX with a photon.
The library uses only the high level firmware API. So it should also run on different hardware. On the other hand, this means that the implementation is not very efficient. It might produce some unnecessary CPU overhead and produce bad output if the timer function is interrupted by the system.
