WebA 30 MHz CAN clock gives us Tpclk of 33.33 ns. 1.67 μS / 33.33 nS gives us almost exactly 50 clock ticks per bit time. A good rule of thumb is to have your sampling point at 70-80% of the nominal bit time. More towards 80% the higher the baud rate. So let's set BRP[9:0] to 4 which gives us: Tq = (4 + 1) x 33.33 ns = 166.65 ns pop ups on facebook

WebCAN network has its own clock generator, usually a quartz oscillator. The timing parameter of the bit time (i.e. the reciprocal of the bit rate) can be conﬁgured individually for each CAN node, cre-ating a common bit rate even though the CAN nodes’ oscillator periods (fosc) may be different. WebThe TQ interval must be calculated based on the clock and various BRP values, and only the combinations where the TQ interval divides into the bit time by an integer number are possible.
