WebDec 1, 2024 · CAN messages, also known as frames, are rather simple consisting of a start bit, arbitration field, message information, data, CRC, some additional (but not entirely important ACK bits), and the end frame. The start bit is a 0, and thus causes the two lines on the CAN bus to take different voltages.
WebAug 16, 2024 · The message begins with the Start Frame, which indicates the start of the message.
