Welcome to the forum

What makes you think that an error is occurring ?

3

i am unable to do anything when upload the script, or perhaps i do not know how to use it !

but i get the following message, which i thought was a error
ketch uses 7600 bytes (23%) of program storage space. Maximum is 32256 bytes.
Global variables use 481 bytes (23%) of dynamic memory, leaving 1567 bytes for local variables. Maximum is 2048 bytes.

The message is telling you how much memory is being used. Note that only a relatively small percentage is being used which is good news

How exactly is the shield connected to the car OBD port ?

5

ok thank you ,

DB9 connector to OBD2 port of car,

6

What do you expect to happen run you run the sketch ? What, of anything do you see on the Serial monitor ? Does the baud rate set in the Serial monitor match that set in the sketch ? How do you interact with shield to set what values are displayed ?

Please post the sketch that you are running, using code tags when you do

7

ok i just tried this while plugged into OBD of car and i got characters but of no real information such as Zeros and 1s as expected.

so what i am looking to do is this this canbus shield to read the CAN HI and LOW, using pin 14 and 6 of the OBD connector ( Can Hi / Lo)

8

Are you sure that you are using the correct baud rate ?

9

back at the car again and now getting serial data, :slight_smile: it was Baud rate and possibly spi CS pin!

Hi, @autosparkrhys
Welcome to the forum.

Can you please post your code?
Can please post a schematic.

Have you got gnd connected between the CanBus module and the OBD socket?

Thanks.. Tom.. :grinning: :+1: :coffee: :australia:
