Can bit timing calculation for bxcan

WebACAN_STM32 is a driver for the bxCAN module built into several STM32 microcontroller. The driver supports many bit rates, as standard 62.5 kbit/s, 125 kbit/s, 250 kbit/s, 500 kbit/s, and 1 Mbit/s. An efficient CAN bit timing calculator finds settings for them, but also for exotic bit rates as 842 kbit/s. 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
