canqv is a small C-program which shows a (subset of a) list of CAN frames found on a CAN bus. The main goal is to provide a quick view on CAN.
$ canqv can0
Outputs a refreshing list of found CAN identifiers on the terminal. The list is sorted, and contains the databytes of the last CAN frame with the CAN identifier, and a guess of the repetition period is shown next to the CAN frame.
canqv vs. cansniffer
cansniffer requires CAN_BCM sockets, and is limited to 11bit CAN identifiers.
canqv overcomes these limitations, with higher cpu-load as a consequence.
Cross-compiling is done by creating config.mk in the libenumif root. config.mk may add, overrule, extend Makefile variables.
