Can bit timing calculation for bxcan

Web3.1 BXCAN MAIN FEATURES The basic extended CAN - called bxCAN - supports: CAN protocol version 2.0 A, B Active Bit rates up to 1Mbit/s at 8MHz Three transmit mailboxes Priority by identifier or FIFOs Two receive FIFO with three stages each Eight scalable filters – Can be associated with FIFO 0 or 1 – Identifier list feature WebThe bit timing for each node in a CAN system is derived from the reference frequency (fOSC) of its node. This creates a situation where phase shifting and oscillator drift will occur between nodes due to less than ideal oscillator tolerances between the nodes.

Web3.1 Nominal bit calculations at base frequency These values have been calculated based on the base frequency and nominal bitrate. Note the max cable length (as given by T bus_time) below. The sample point may be adjusted using the +/- buttons. Moving the sample point results in a trade off between between cable length and tolerance margin.
