thankyou so much for great library, i'm trying to send lin signal and it doesn't work after i see with oscilloscope i found it doesnt have start bit and stop bit. can you help me how to setup startbit and stopbit?

has it ever run on a teensy 4.0 ???

I've tried a lot, unfortunately without success.

Hello Markus,

I've tried to use your library on a Teensy 3.6. Unfortunately I'm getting an error when I try to compile it.

Even with the examples that come with your library. I've attached an txt file with the error message.

I've tried to compile the example for Teensy 3.2 and it worked..

It seems that there is a problem in declaration of the serial interfaces on Teensy 3.6. But I'm not experienced enough for further analysis
Is it possilbe that you take look into it?

Thanks in advance :-)

Hello, I think I found a mistake. From the information I found on the LIN 2.x standard, the enhanced checksum should be calculated using the protected id and not the raw id. I fixed the issue replacing PID with send_pid in line 424 of lin_bus.cpp. I hope this information can be helpful.

I tested the LIN-Bus on Teensy 4 and I got no Break Field.

BTW, a very good job!

Best regards

Hi!

what is the reason there is a limitation of possible breakbits for configurating LIN Master?
And why is it different with the teensy model used?

Because I would need more breakbits for my application...
Guess it has to with UART, but cant tell why and how to fix it.
