Added new tool 'canplayer' to replay logfiles generated by candump -l . Features of canplayer: - Input from stdin or file. - throttling of the replay to get nearly original timestamps / message gaps - mapping and selection of CAN interfaces (assignment) e.g. canplay -I logfile vcan2=can2 vcan0=can1 can2=can3 means: send frames received on can1 in the logfile to vcan0 and so on ... - if no assignment is made the original interfaces are used for replay - handling of multiple CAN interfaces simultaneously (if in logfile) - option: throttle disable (do not look on timestamps => very FAST replay!) - option: change the 'sleep time' in milli seconds Remarks: canplayer uses nanosleep() for throttling which means that the resolution of the canplayer is about 1ms (Kernel HZ = 1000) or 10ms (Kernel HZ = 100). After each nanosleep() all the CAN frames are send that had to be transmitted until the timestamp at the current time. Giving e.g. the option '-g 500' for 500ms let's you see the behaviour. Using nanosleep() makes canplay a very performant tool with minimum CPU load. To transfer CAN frames over a TCP/IP network you may now say something like: candump -> netcat -> netcat -> canplayer
