Hello all, When i switch on the unit, the GPIO ports give me the 3,3 voltage, unless i configure it to be output. When the project runs, these GPIO ports come to 0V, but there´s anyway to have allways 0V, even when i switch on the unit? We need lights not to switch on during the unit powerup. How could i do it? Thanks

  I'm not sure if this can be changed.
  
  We could try temporarily setting your gpios to outputs at starup. I don't know if it's the enabling of the gpios causes the lights to come on. Are you using a script to do this or a brightauthor project?

  Hello,
  
  I´m using BrightAuthor..
  
  I though maybe it could be done with a script, but the autorun.brs runs when you switch on the unit, and I think there will be a moment, before run the script, that lights will be on.
  
  I think maybe it could be done at the setupfile, when you configure the unit, because of these settings are saved into the BrightSign unit..
  
  I don´t really now if it´d be possible
  
  Thanks
