kvBusParamsTq Struct Reference

#include <canlib.h>

Data Fields
int	tq
int	phase1
int	phase2
int	sjw
int	prop
int	prescaler

Detailed Description

Constraints

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

Used in canSetBusParamsTq, canSetBusParamsFdTq, canGetBusParamsTq and canGetBusParamsTq
