WebThe number of time quanta per bit (known as the bit time) can range from 8 to 25. There is no analytic formula for determining the optimum bit time in advance, so the calculator tries all of them. The closest integral baud rate prescaler is calculated for each value. The BRP and Tq/bit values are then used to calculate the actual sampling bit rate. WebThe CAN bus was developed by BOSCH (1) as a multi-master, message broadcast system that specifies a maximum signaling rate of 1 megabit per second (bps). Unlike a traditional network such as USB or Ethernet, CAN does not send large blocks of data point-to-point from node A to node B under the supervision of a central bus master. WebE.g. With 48MHz CAN clock frequency, 125K bit rate can be achieved with NBT = 8, 12, 16 and 24 Tq, with 0% deviation in the bit rate. From these four choices an appropriate value of NBT needs to be determined along with the bit time segments and the RJW value. While determining these values, the following characteristics have to oracle conject bau

WebSample Rate - The legislated signals have a slower update rate than normal CAN bus channels. Active vs Passive - These signals are not broadcast by default, and need to be requested by the measurement device. This requires setting the ‘CAN Acknowledge’ mode to ‘Active’ rather than ‘Passive’ in Simcenter Testlab CAN settings. WebIf setting up a bus that is 12 inches long the sampling point could be at 50% and the bus will run just fine. If connecting to someone else's bus of unknown length and setup then maximize your chances.
