Upload DCC++ EX to Mega2560 TimerA fault #180

Closed muddster closed 3 years ago

muddster commented 3 years ago

I installed DCC++ EX in my Arduino folder and tried to upload it to a Mega2560. I received the following error.

sketch\Timer.cpp.o (symbol from plugin): In function TimerA': (.text+0x0): multiple definition of__vector_20' sketch\DCCTimer.cpp.o (symbol from plugin):(.text+0x0): first defined here collect2.exe: error: ld returned 1 exit status exit status 1 Error compiling for board Arduino Mega or Mega 2560.

Does anyone know why this is happening and how to resolve it?

Many thanks, Brian Mudd

Make sure you have all the timer libraries installed....use the library manager

Hi Brian, you most likely had an older version and copied over it. It is picking up definitions from a file that is no longer part of the code and shouldn't be in that folder (Timer.cpp). Start clean. Delete the folder and then unzip it from here: https://github.com/DCC-EX/CommandStation-EX/releases. That will make sure you have only the files you need. If you already had a config.h file, it will not be overwritten. If you need one, just rename config.example.h to config.h. Make any changes you like to config.h and upload.

Thank you very much FrightRisk, that solved the problem.
