git submodule update --init
or
git clone --recursive https://github.com/ebroecker/candecodes
Compile

Usage
candump -L canBus | ./candecode dbc-file frameName[.signalName] [secondFrame[.someSignal] ...]
Example
candump -L vcan0 | ./candecode ccl_test.dbc testFrame1.sig0 testFrame2
Test
prepare virtual can:
sudo modprobe vcan
sudo ip link add type vcan
sudo ifconfig vcan0 up
dump vcan0 with signal decoding:
candump -L vcan0 | ./candecode ccl_test.dbc testFrame1 testFrame2
send some can frames (other terminal)
cansend vcan0 001#8d00100100820100
cansend vcan0 002#0C00057003CD1F83
will result:
