library DmxDue USART0_Handler redefinition

[livello]

Example compilation problem. Please, look at https://github.com/livello/lighthub/tree/due-dmx-test

.pioenvs/due/lib3d5/libDmxDue.a(DmxDue.o): In function USART0_Handler': DmxDue.cpp:(.text.USART0_Handler+0x0): multiple definition ofUSART0_Handler' .pioenvs/due/libFrameworkArduinoVariant.a(variant.o):variant.cpp:(.text.USART0_Handler+0x0): first defined here

Unfortunately, I didn't find other way to avoid conflict between embedded Serial handler and DMX Serial libs, but comment handler in variant.cpp

Patched variant.cpp in https://github.com/anklimov/lighthub/tree/master/DUE_to_replace_sysfile

Is USART0_Handler used only for Serial.print routine? Can we leave it for Arduino regular needs?

[anklimov]

in Arduino DUE USART0 (used by DMX) mapped to Serial1 Serial class (normally used for regular Serial.print) is mapped to UART
