I want play rgb dmx sequence from sd card. I found Vixen software but is more step for transform file to arduino compatibiliti.
A little like this https://www.amazon.co.uk/WS2812-Player-Plays-effects-card-x/dp/B00LN3X9BU
Or do you mean DMX output ?
Many thanks. intersting your link but i use pwm rgb light for output... this is project. with pixels is more easy. thanks again.
