## NAME

can-calc-bit-timing - manual page for can-calc-bit-timing 2023.03-1

## SYNOPSIS

**can-calc-bit-timing** \[*options*\] \[*\<CAN-contoller-name\>*\]

## DESCRIPTION

can-calc-bit-timing - calculate CAN bit timing parameters.

## OPTIONS

- **-q**

  don't print header line

- **-l**

  list all support CAN controller names

- **-b** \<bitrate\>

  arbitration bit-rate in bits/sec

- **-d** \<bitrate\>

  data bit-rate in bits/sec

- **-s** \<samp\_pt\>

  sample-point in one-tenth of a percent or 0 for CIA recommended sample points

- **-c** \<clock\>

  real CAN system clock in Hz

- **--alg** \<alg\>

  choose specified algorithm for bit-timing calculation

Or supply low level bit timing parameters to decode them:

- **--prop-seg**

  Propagation segment in TQs

- **--phase-seg1**

  Phase buffer segment 1 in TQs

- **--phase-seg2**

  Phase buffer segment 2 in TQs

- **--sjw**

  Synchronisation jump width in TQs

- **--brp**

  Bit-rate prescaler

- **--tseg1**

  Time segment 1 = prop-seg + phase-seg1

- **--tseg2**

  Time segment 2 = phase\_seg2
