"multiple definition of " errors

[redsunpost]

Found the problem, something I did myself 🐰 The 2 files .h and .cpp were present in the project folder which gave a conflict when verifying the code. Newby error, hope it helps someone in the future :)

I stumbled upon your github here and wanted to try and get my VFD going, not sure what is going on is this an error in the library?

I'm using an arduino uno r4

thanks :)
