beaglebone and OBD model B (ic2)

Post by eoinverling »

Hi,

I have a OBD-II model B ic2 adaptor, connected to my car. I have a beaglebone black connected to ic2 ports (and GND, needed that to get it to work!) ... from the beaglebone I can do:-

# ic2detect -y -r 1 (when connect to that ic2 bus!)

which sees 2 x ic2 devices at address 0x60 and 0x68. I could then "ic2dump" the contents, etc

The documentation for the OBD adaptor says:-

"Model B connects with Arduino through I2C interface (SDA/SCL). OBD-II data and MEMS sensor data are both accessed via I2C. The OBD library has encapsulated all the necessary I2C operations for OBD-II access."

so, my questions

1. do the 2 x detected device addresses correspond to the OBD-II and MEMS sensor?
2. in a non-Arduino world (in this case, beaglebone), is it possible to get at the encapsulated OBD data on the ic2 bus?

any help / pointers would be appreciated
