WebJan 31, 2024 · In CAN bus timing, each bit is synchronized and divided in a number of units known as time quanta (tq). When configuring the baudrate, one should strive to get the sample point as close to 87.5% of the bit length as possible (industry de facto and CANopen standard). We do this by configuring the length of the various tq segments. WebHowever, for the bit timing, per FDCAN specification, there are 2 bit times: the nominal (like standard CAN) and the one for the fast data. So far so good. For the nominal bit …
