is cannucleo compatible with MBed OS ?

The original processor 411RE does not support CANBUS.in hardware, any board will do except that one.

now that I have changed to the STM32F072, it still does not compile.

The functions in MBed CAN are duplicated in cannucleo

it compiles and works ok online, but not offline using MBED-CLI

Hello Nick,
CAN support has been recently built into the mbed library also for the NUCLEO boards. I'm sorry for the inconvenience but the manner how it's implemented into mbed revision 128 and 129 does not allow me to maintain the CANnucleo library anymore. If you prefer to use it anyway (have a look at https://developer.mbed.org/users/hudakz/code/CANnucleo/ for the list of boards supported) then you have to switch the mbed library in your project back to revision 127 or earlier.
NOTE: Although it might be due to a mistake on my side but the built-in CAN support does not work yet with my NUCLEO-F103RB board.
