Web10. Turns out the answer should have been obvious from the waveforms above. When TX goes low, so does RX. But when TX goes high, RX takes more than 1us to rise again. That's more than a whole bit time! CAN cannot work under these conditions. The reason RX lags behind TX would have been obvious with a proper oscilloscope, rather than a simple ... 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.
