"The rise time of a signal is the time difference between the crossing of the lower threshold and the crossing of the upper threshold for a positive- going edge. The X cursor shows the edge being measured." My confusion is that I never set thresholds. WebCAN bus with flexible data-rate (CAN FD) is an extension of the Classical CAN data link layer. It increases the payload from 8 to 64 bytes and allows for a higher data bit rate, dependent on the CAN transceiver. This enables increasingly data-intensive use cases like EVs. CAN FD intro.
