No Break Field in Teensy 4 #2

Closed GitSchorschGit closed 2 years ago

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

BTW, a very good job!

Best regards

Hi, I too have this same issue on a Teensy 4.0. The rest of the message is bang on, but nothing recognises it because the break field is missing.

Please find attached a Pico Scope UART conversion of the Teensy tx pin going to the LIN transceiver of your example file 'NCV7430_Get_Full_Status.ino' to illustrate the issue.

Any help with this would be much appreciated!

Very nice Chart where did you get it from. Problem solved, Hardware-UARTS had to shift around. Please test again

I made it from the data being transmitted from your library whilst decoding the message in picoscope. It’s a screen grab with screenpresso which then has a nice edit and annotate feature - I’d really recommend the software, I use it on all my pc’s daily.

Thank you for looking into this for me - I’ll try to get the code tested later today and get back to you!

Kind regards,

James
