Re: Beaglebone Black to i2c obd-ii adaptor b ..

Yes there are 2 devices one for OBD (addr 0x62) and one is MEMS (MPU-6050, addr 0x68). For writing your own code to communicate with them, please refer to the Arduino library sketches here:

Re: Pre-buy question: kit #3 as live lap timer?

Surely you can do that with the kit by obtaining and keeping the GPS coordinates of the start point and detect the passing of that point. Physical buttons are handy for in-vehicle operation. They can be connected via LCD shield's spare Serial connector (can be used for digital I/O) or I2C connector ...

Re: Metric VS US Units

OBD-II standard does not use MPH for speed. For the GUI, you can modify the code if you are capable of that. The GUI is open-source.

Re: OBD2 EMULATOR

The emulator does not require computer to work. However, to change the emulation data, you need a control interface and that's either a computer or an iPhone/iPad. The emulator has serial UART connector and that's for programmatically controlling with an external device (e.g. an Arduino).

Re: Duplicate PID

Sorry for the confusion. All OBD PIDs defined in OBD.h are for mode 01. So when they are actually logged, they will appear as 1XX where XX is the definition in OBD.h.
