Hello @byao.1​ 

Thanks for your feedback, in fact, some modifications were made to CAN in the 6.1.0 CubeMX version to make the "Time for one bit" more precise.

As you can see, with this configuration the "Time for one bit" equal to 999.99 ns, and this value should take at least 1000 ns, but following your requests, we decided to make this value acceptable by CubeMX for the next release.

Thanks, Khouloud
