# Interface: CanBusParams

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

## Properties

### phase1

> **phase1**: `number`

The number of time quantas in phase 1.

***

### phase2

> **phase2**: `number`

The number of time quantas in phase 2.

***

### prescaler

> **prescaler**: `number`

The prescaler value.

***

### prop

> **prop**: `number`

The propagation segment in time quantas.

***

### sjw

> **sjw**: `number`

The synchronization jump width in time quantas.

***

### tq

> **tq**: `number`

The total number of time quantas (TQ).
