Nissan Leaf ZE1 AC compressor LIN

or try to log / playback to the compressor not attached to the car.

You got a LIN setup with an arduino might be worth trying.

Playing back is not possible with the USB Analyser.

I don't,
But I should have the bits to make a LIN setup, just a level shifter required by the looks of it?

Check CRC? ID47

Check CRC? ID47

The CRC is calculated as the Avanched LIN 2.0 CRC and it checks out as correct according to my Lin capture device. But can mess around a bit with this.

I work with LIN, and have the same problem. I think your problem was wrong ID, because in LIN can be protected ID, and check CRC. I try any Arduino Lin library and some have problem with it.

Okay so you would not believe the issue. Message timing.

I reviewed logs and my code and noticed even though it is supposed to run even 100ms the loop was not being ran that fast. So adding it to a mytimer call back it now send the the LIN frames at 10Hz as per log. I believe you could theoretically run it at a slower speed, seems to try and go at 3Hz but need more testing.

Should have realised from your post too, each frame ever 100ms. (10hz)

Hello, this post may help you if you need to send LIN with an Arduino:
