CanBusParams is used for getting the channels bus params capacity and it can be used for setting up a correct bus speed configuration for a specific CAN channel.
Constraints that must be fulfilled when opening channel in classic CAN Mode:
tq = 1 + prop + phase1 + phase2 tq >= 3 sjw <= min(phase1, phase2) prescaler >= 1
Constraints that must be fulfilled when opening channel in CAN FD Mode:
arbitration.tq = 1 + arbitration.prop + arbitration.phase1 + arbitration.phase2 arbitration.tq >= 3 arbitration.sjw <= min(arbitration.phase1, arbitration.phase2) arbitration.prescaler >= 1 (<=2 will enable Transmitter Delay Compensation Mechanism)
data.tq = 1 + data.phase1 + data.phase2 data.tq >= 3 data.sjw <= min(data.phase1, data.phase2) data.prop = 0 data.prescaler = arbitration.prescaler
