Thread: OBDSim now with multi protocol, benchmarking

This has been discussed on and off in a couple other threads, but I thought I'd put them together in one place.

I've added a couple features to obdsim recently that may be of interest to forum regulars: Proper multiple protocol support, and benchmarking. Now any time you attempt to use ATSP[A]{1-9} it'll do the right thing, ATH1 will cause it to show headers appropriate to the protocol you have requested.

For example, here showing two ECUs with J1850 VPW, and 11 and 29 bit CAN:

Code:

>ATDP
SAE J1850 VPW
>0100
48 6B 10 41 00 18 1B 80 01
48 6B 11 41 00 FF FF FF FE
>ATSPA9
OK
>0100
18 DA F1 10 06 41 00 18 1B 80 01
18 DA F1 11 06 41 00 FF FF FF FE
>ATDP
Auto, ISO 15765-4 (CAN 29/250)
>ATSP8
OK
>0100
7E8 06 41 00 18 1B 80 01
7E9 06 41 00 FF FF FF FE
>ATH0
OK
>0100
41 00 18 1B 80 01
41 00 FF FF FF FE

Additionally, I've now added benchmarking. You can pass "-n" or "--benchmark" to enable it [in future I'm thinking I'll just enable it all the time]. --benchmark takes an optional parameter that says how many seconds it should group the benchmarks by [default 10]. For example, with benchmark=5, and running obdgpslogger against it:

Code:

chunky@mills:~/src/obdgpslogger/build$ ../bin/obdsim --benchmark=5
SimPort name: /dev/pts/5

For windows users, I've finally automated my build process specifically for obdsim on windows. The current version is here: obdsimwindows-2010-06-16.zip. It includes a short text document showing how to use it as well as a text flavor of the manpage.
