can-send

The purpose of the command-line tool can-send is to send CAN data frames to an active CANpie FD Server channel.

Description

can-send [options] interface

The options are as follows:

-h, --help     Displays this help.
-D <dlc>       Set DLC to <dlc>
-f <format>    Set frame format to [CBFF|CEFF|FBFF|FEFF]
-g <gap>       Time gap in milliseconds between multiple CAN frames
-H <host>      Connect to <host>
-i <I|D|P>     Increment the requested type
-I <id>        Set identifier to <id>
-n <count>     Terminate after transmission of <count> CAN frames
-P <payload>   Set payload to <payload>, i.e. a string of hex values
-v, --version  Displays version information.

The command requires a CAN interface as argument, where can1 is the first CAN interface.

Examples

Send a CAN data frame in CBFF with identifier 33 and DLC 4 on CAN interface 1:

can-send -I 33 -D 4 can1

Send 10 CAN data frames with a starting identifier of 100; increment the identifier for each subsequent CAN frame. Use a gap of 100 ms between transmissions on CAN interface 2:

can-send -I 100 -D 0 -iI -n 10 -g 100 can2
