cansniffer - manual page for cansniffer 2023.03-1
SYNOPSIS
cansniffer [can-interface]
DESCRIPTION
cansniffer - volatile CAN content visualizer.
OPTIONS
-q (quiet - all IDs deactivated)
-r <name>
(read sniffset.name from file)
-e (fix extended frame format output - no auto detect)
-b (start with binary mode)
-8 (start with binary mode - for EFF on 80 chars)
-B (start with binary mode with gap - exceeds 80 chars!)
-c (color changes)
-f <mode>
(CAN FD mode: 0 = OFF, 1 = ON, 2 = auto detect, default: 2)
-t <time>
(timeout for ID display [x10ms] default: 500, 0 = OFF)
-h <time>
(hold marker on changes [x10ms] default: 100)
-l <time>
(loop time (display) [x10ms] default: 20)
-? (print this help text)
Use interface name 'any' to receive from all can-interfaces.
commands that can be entered at runtime:
q<ENTER>
- quit
b<ENTER>
- toggle binary / HEX-ASCII output
8<ENTER>
- toggle binary / HEX-ASCII output (small for EFF on 80 chars)
B<ENTER>
- toggle binary with gap / HEX-ASCII output (exceeds 80 chars!)
c<ENTER>
- toggle color mode
@<ENTER>
- toggle ASCII output (disabled for CAN FD by default)
<SPACE><ENTER>
- force a clear screen
#<ENTER>
- notch currently marked/changed bits (can be used repeatedly)
*<ENTER>
- clear notched marked
rMYNAME<ENTER>
- read settings file (filter/notch)
wMYNAME<ENTER>
- write settings file (filter/notch)
a<ENTER>
- enable 'a'll SFF CAN-IDs to sniff
n<ENTER>
- enable 'n'one SFF CAN-IDs to sniff
A<ENTER>
- enable 'A'll EFF CAN-IDs to sniff
N<ENTER>
- enable 'N'one EFF CAN-IDs to sniff
+FILTER<ENTER> - add CAN-IDs to sniff
-FILTER<ENTER> - remove CAN-IDs to sniff
FILTER can be a single CAN-ID or a CAN-ID/Bitmask:
single SFF 11 bit IDs:
+1F5<ENTER> - add SFF CAN-ID 0x1F5
-42E<ENTER> - remove SFF CAN-ID 0x42E
single EFF 29 bit IDs:
+18FEDF55<ENTER> - add EFF CAN-ID 0x18FEDF55
-00000090<ENTER> - remove EFF CAN-ID 0x00000090
CAN-ID/Bitmask SFF:
-42E7FF<ENTER> - remove SFF CAN-ID 0x42E (using Bitmask)
-500700<ENTER> - remove SFF CAN-IDs 0x500 - 0x5FF
+400600<ENTER> - add SFF CAN-IDs 0x400 - 0x5FF
+000000<ENTER> - add all SFF CAN-IDs
-000000<ENTER> - remove all SFF CAN-IDs
CAN-ID/Bitmask EFF:
-0000000000000000<ENTER> - remove all EFF CAN-IDs
+12345678000000FF<ENTER> - add EFF CAN IDs xxxxxx78
+0000000000000000<ENTER> - add all EFF CAN-IDs
if (id & filter) == (sniff-id & filter) the action (+/-) is performed, which is quite easy when the
filter is 000 resp. 00000000 for EFF.
