Reply To: compile error: variable ‘bitrate_table’ must be const

[Anonymous]

Hi Michael,

Thanks for your fast anwer and help, it solved the problem I had, but I got new compilation (linking) erros. I put the compilation messages and errors under this message.

avr-gcc is version 4.7.0 so you where right about the problem

Do you have any idea how to solve the new errors?

Thanks,

Mikel
