I have also another problem with a task,perhaps somebody can tell me how I should paint it in 1)?
1. Sketch a CAN message at a speed in a voltage-time diagram
of 500 kbps (high-speed) and the data bytes 0xBF, 0xAA (ID = 0xB5,
Standard frame). The voltages to be applied are UCAN-H-M acse, UCAN-L-M acse
and UCAN-H - UCAN-L. Use the prepared diagram (see Appendix
A). The CRC checksum is: 1010 1110 0100 0011.
2. A second SG wants to access the bus at the same time and transmit the following message:
ID = 0xA8, data bytes 0xB0, 0xFF. Which of the two news wins the
Arbitration process with simultaneous bus access?
I agree he is talking about canbus, a type of signal (analog, I think?) that is common on some types of engines and similar hardware. ?? I used it very briefly long ago, but can't recall much beyond it being difficult to work with.
