Hallo allemaal !
Hopelijk vind ik hier wat hulp voor mijn projectje.Ik heb meerdere Arduino Nano's die ik ws2812 led-strips (per Arduino 3) laat aansturen. De Arduino's gebruiken SeriaDMX (https://github.com/mathertel/DMXSerial) voor het uitlezen van een DMX signaal op de serial poort. Zo gebruik ik bijvoorbeeld kanaal 1t/m12 voor Arduino 1, en kanaal 20t/m32 voor Arduino 2 etc. Ik loop helaas tegen wat problemen aan... zo storen de Arduino's behoorlijk als ik de kanalen zoals net beschreven gebruik; kanaal 100t/m112 voor Arduino 2 geeft veel minder problemen. Het zorgt er in ieder geval voor dat ik concreet de volgende vraag heb:
- ik zou graag de uit te lezen kanalen per Arduino begrenzen... het lukt me wel een 'bovengrens' te bepalen maar echt 'afschermen' van kanaal 20t/m 32 lukt me niet. Kan iemand me hierbij helpen ?
Bij aan Arduino die kanaal 500 t/m 512 uitleest ontstaan al helemaal problemen overigens... ik kan niet helemaal beredeneren waarom helaas.
Alvast heel erg bedankt voor het meedenken
Groetjes, Martijn
