WebCAN FD (CAN with Flexible Data-Rate) is an updated version of the CAN 2.0B protocol. It takes into account the demand of the automotive industry to make the classical CAN faster. In order to achieve that, two principles have been introduced: – The classic CAN frame contains 0-8 data bytes. The CAN FD frame contains 0 – 64 databytes.
