DMXSerial library with Arduino Mini pro or Nano

Hi,

is it possible to use the library DMXSerial with an arduino mini pro ?
It's all right with my Uno but nothing with my Mini Pro :frowning:

And with a Nano board ?

Thanks,

Hugo

Sure, why not? Same '328P processor on all 3 cards.

Maybe you need something to adapt the Rx/Tx pins to DMX signal levels? Aren't they RS485 levels?
