DMXSerial has conflict with SD library

[dstueven]

I am trying to use the SD library (to read a file from an SD card) and DMXSerial together. Unfortunately both seem to define the same interrupt - the compiler throws an error - even if I compile a totally empty project with just the two include statements.

My minimized test sketch:

include

include

void setup() { // put your setup code here, to run once:

}

void loop() { // put your main code here, to run repeatedly:

}

The error messages of the compiler: Arduino: 1.8.5 (Windows 10), Board: "Arduino Ethernet"

HardwareSerial0.cpp.o (symbol from plugin): In function `Serial':

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

This is a know issue of the SD library: It uses the Serial interface for debugging output purpose.

I propose you to remove all the Serial references in your local SD library.
