Hi,

I have OBD II adapter and Ardinou UNO. I tried to test the OBD adapter, I put the OBD library in the library directory, when I complie the code I get this errors:

How to solve this problem?

thank you

Hi Stanley,

I purchased the kit to talk to my car via ISO9141 protocol. Any sample/code snippet would be much appreciated!

Thanks.

hello. I bought this OBD adapter (model b)couple days ago. I believe it's on its way to my home. before it gets here. I have a question.

I have a delegated MPU6050 (GY-521) which has a INT port on it. I connected this port to D2 port to my UNO 3. so I can use interrupt read. but I did not find any information of this port on this OBD adapter.

can you give me some clue? thanks!

Hi Stanley, I have your OBD2 interface and would be interested in getting trouble codes (like P0172, etc.) and reset the trouble codes and MIL light. Can it be made available in the library?
Thank you!

[mafbass]

Yep! Are you going to implement it in the near future?

Hi, @stanleyhuang

How much current while the adapter consumed when it is idle ?

Or, is there any way to put the adapter into power-saving mode. Since I don't what to plug/unplug the adapter every time when i start/stopped the engine, otherwise the battery may drained out if I park the car for a few days or weeks.

Thanks in advance.

With the power consumption issues while the car if off and the fact that it seems I must always plug in my adapter after the ignition is ON - is it possible to rewire the adapter so it receives power from the arduino 5V pin rather then supply it?

this way the arduino could be wired to a switched 12V circuit and the kit would automatically have its power cut when the ignition is OFF, and automatically first establish communications when the ignition is ON

As soon as I have time, I will.

Yeah thank you! Looking forward for it!  ;)

As soon as there is code available in the library to check engine codes (CEL codes and such) and turn of the CEL, this adapter would be perfect for my project, and I'll buy one. I hope it becomes available soon!

Thanks!

I cannot get any of the code to verify, even the RPM Led UART example...  I use IDE 1.0.3 and 1.5.5, both have same errors..  Any suggestions?    I made sure OBD.cpp and OBD.h are included...    thanks
