WebI tried setting BRPR =6, TS1 = 12, TS2 = 1, SJW = 0 (1 less for TS1, TS2, SJW as per product guide) for 250Kbps speed at 24MHz and have selected in PCAN view also the same settings (24MHz & 250Kbps). Are these values correct? How to calculate bitrate depending on clock, prescalar and time segment values. Regards, Bhavin 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. north island crypto fund
