Stanly, any plans to implement the J1939 protocol in the emulator?
I know that this is not a OBD-II protocol but it should be realy nice to have this for me

Found the answer

write 0902 to ask for the VIN.

With a VIN of WP0ZZZ99ZTS392124 in the OBD-simulator a got this respond back:

014 0: 49 02 01 57 50 30
01: 5A 5A 5A 39 39 5A 54
02: 53 33 39 32 31 32 34

According to the ELM327 specification:

014 - 014 bytes of information (HEX)
0:-sequence ...

Any ideas how to read out the VIN number?

I can see that there is a declaration of a variable called vin in odb.h
line 123: // current VIN
line 124: byte vin[17];

but I can´t find any function that reads the actual VIN from the OBD interface...

Do I need to implement that function or am I missing ...

Ok

I reduced the code so now it works

Thx for the help

Ok, but isn´t your unologger program supposed to run on a UNO? Or do I need to modify it to be able to run int on a UNO?

I´m not using any display-shield. Just a OBD I2C interface and a GPS/SD-shield.

I will remove the display part of the code and give it a try.

Ok

But isn´t your unologger program supposed to used on a standard UNO?

I´m not using any display shield. Only the I2C OBD interface and a GPS/SD shield.

I will take away the display part to reduce the program size.

Hi

I get and error when I try to upload the "unologger" project to an Arduino UNO using the build in Arduino Builder in Codeblocks.
(downloaded from m, downloaded 17-08-2014)

Everything compiles fine in Codeblocks but the upload always stops at 94% and an error message appears.
The message says ...
