My issue right now is deciding between this:
device
http://freematics.com/store/index.ph...&product_id=30
api
https://github.com/stanleyhuangyc/ArduinoOBD
-better example code
-would have to write my own mode 2 code (I believe the 2101 PID for oil temps on the brz/frs is mode 2?)
-author of library is kind of "short" with people on his help forum...not so forthcoming...I did send him and email and posted my questions. I guess we'll wait and see.
OR
the sparkfun one
device
https://www.sparkfun.com/products/9555
api example
https://github.com/sparkfun/OBD-II_U...Quickstart.ino
-less sample code
-fairly straightforward though
-you send obd II instructions to the uart device and is dumps the hex back that it gets from obd II
-You just have to write functions to get the stuff back and do something with it (which is fairly straightforward)
I keep asking about mode 2 OBD II because of the torque pid that was ID'd a little while ago (
http://www.gps-laptimer-forum.de/vie...hp?f=20&t=1364). It is 2101. I believe that means it is mode 2 0x65 . On a harry's lap timer thread someone says it returns 31 bytes which seems excessive and incorrect. Although someone did the probing and it might be right.
