CAN and CAN FD bus decoding – overview CAN bus (Controller Area Network) is a serial data standard originally developed in the 1980s by Robert Bosch GmbH for use in automotive applications. Today it is also widely used in industrial process control and aerospace applications. It allows microcontrollers and electronic devices to communicate with each other without using a host computer and provides fast and reliable data transfer in electrically noisy environments at low cost and with minimal wiring. CAN employs differential signaling to provide a high level of immunity to electrical noise. PicoScope software allows many frames of CAN and CAN FD (Flexible Data-rate) data to be fully decoded both in a table format and in a colour-keyed trace, time aligned with the data signal.
