Programa DMX para Arduino, no compila.

#1
Este programa lo bajé de la página que aquí aparece y aparentemente está completo.
Tengo algunos equipos de DMX que quiero poner a funcionar.

Ya tengo la interfaz de comunicación con integrados MAX485, uno de entrada y otro de salida.
Habilitados directos o puedo usarlos como vienen en el programa, no hay problema.
Aclaro que llevo 2 meses clavado en tener un programa DMX que funcione.

Les incluyo el código para Arduino y al final los errores.
Son pocos errores. ¿Quién le echa un vistazo? ¿Qué me falta?

Última edición por un moderador:
#2
El error dice que el compilador no tiene ni idea qué es Addressing() y qué es action().

Creo que te falta poner un #include

hola
Este programa lo bajé de la página que aquí aparece y aparentemente está completo.

Son pocos errores. ¿Quién le echa un vistazo? ¿Qué me falta?

Saludos a todos.
bueno ., viendo el programa ., y leyendo un poco tu comentario .,​
estoy confundido ., ¿¿¿¿¿ que querés hacer ????. ¿¿¿ un transmisor o un receptor dmx ????​
como decis que tenes., varios receptores y varios modulos 485​
la parte de la compilación que mostrás es para un receptor​
El error dice que el compilador no tiene ni idea qué es Addressing() y qué es action().

Creo que te falta poner un #include
amigo juaquin ., lo que le falta es la libreria con el protocolo para poder manejar la USART ., y es correcto tu supoccion de la falta de un # include​
lo que pasa que no todos se dan cuenta .,​
que en DMX al menos hay que conocer como manejar el protocolo y la deteccion por medio de la USART​
