Hey there!
I am trying to use the DMXSerial2.h library, which uses the Serial to send the DMX data to the shield.
I would like to also use the SevenSeg.h library, but those don't work along. I am asuming that is because both libraries are using the serial. Is there a way to built around this problem? I can include the code if needed 
Thanks in advance!!
Post a link to where you got the libraries from. Please use the chain links icon on the toolbar to make it clickable. Or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.

Please explain exactly what you mean by "don't work". Are you encountering a compilation error or does the code compile and upload fine, but then not work as expected?
The SevenSeg is downloadable here:
https://github.com/sigvaldm/SevenSeg/archive/master.zip
The DMXSerial2 (by Matthias Hertel) is installed via Manage Libraries.

When compiling, I get this error:

I am compiling for the Mega2560
Thank You for your help!!
Hans-Adolf:
#include <DMXSerial.h>
You said you were using the DMXSerial2 library.
Anyway, I think the problem has absolutely nothing to do with the SevenSeg library. It's caused by using DMXSerial2 library and Serial at the same time. Here's a minimal demonstration:
#include <DMXSerial2.h>
void setup() {
Serial.begin(9600);
}
void loop() {}

Then you can edit DMXSerial2.cpp to use Serial1:
// For using the serial port 1 on a Arduino MEGA 2560 board, enable the DMX_USE_PORT1 definition.
// #define DMX_USE_PORT1
Thank you guys so much!!!

Oooops, I was messing around with the DMXSerial to find out if it changes anything and forgot to change it back..

Deactivated all Serial. Sadly, that didn't help

That worked for me, thank you sooooo much!!!
