Can bus sample rate

WebIn general, the recommended sampling rate for CAN bus or I2C analysis is 10x the bit-rate. If the waveform is not noisy, the sampling rate can be set to around 4-5x the bit-rate. Related Products & Solutions WebIn general, the idea is simple: When just one node is transmitting, the bit-rate can be increased, because no nodes need to be synchronized. Of course, before the transmission of the ACK slot bit, the nodes need to be re-synchronized. CAN FD data frames can be transmitted with two different bit-rates: In the arbitration phase the bit-rate ...

Therefore, the maximum ADC sample rate is: f m a x, A D C = f m a x, S P I 16 = 0.25 MHz. Thus, the processor is the limiting factor here; it can only support a maximum of a 250 kHz sample rate.

CAN data transmission uses a lossless bitwise arbitration method of contention resolution. This arbitration method requires all nodes on the CAN network to be synchronized to sample every bit on the CAN network at the same time. This is why some call CAN synchronous. Unfortunately the term synchronous is imprecise since the data is transmitted in an asynchronous format, namely without a clock signal.
