TM4C1237H6PZ: LIN Master code for Tiva

Hello Alberto.

You can check the following links from ATMEL & MICROCHIP and just do needed modifications (none at large) on TM4C.

In case you need something more on this tell us.

Good luck,

John,

Blasphemy...(I am told.)      Had you noted the requester was a vendor agent?      (I was going to link to ST's, "LIN ready" device... held back to avoid breach of protocol)

Posters would (really) benefit by becoming more "curious" - more "skilled" - and more "active" in their investigative efforts...   (even when they are vendor agents!    No one vendor has "all of the answers" - cross-pollination very often proves immensely instructive & helpful...)

Hello cb1_mobile.

Thank you for your message, but I had already see that requester is a TI's agent. And since TI does not offer LIN on the μC, I send him some links where one can see how it is done algorithmically on C. This is not something bad. I hope it is good for the agent to see how his query may be efficiently tackled at the source/firmware level in the absence of the LIN interface. Where is the problem in this? Hope I didn't cause any problem on the forum, because I post with good-will. I know these companies are competitors, but algorithms, bare or written in C, are not IP in any way, unless patented. And the specs for a firmware level LIN implementation are wide open and free. They are free for all of us to use and built good solutions. Can you imagine CORDIC* being IP !

All the best,

John

John,

You may consider that (sometimes) humor (or teasing) invades a posting.      That said - your earlier inclusion of  your (new) writing, "Some links where one can see how it is done algorithmically in C" would have made your initial post even better - would it have not?

I'm "outsider" - just as you - and find it best to (most always) avoid use of (others') names, part numbers - as such may be seen as, "Crossing an (undrawn) line."

Clearly your finding - then presenting - detailed & helpful links serve as great aid to this (questioning) poster.      And so too - the development of (more) robust investigatory motivation & techniques...

It would seem that your (answering & guiding) post - best deserves that earlier awarded, "Verify!"     (Caveat venditor! ... Let the (real) Forum Seller/(Answer) beware.)

Hello cb1_mobile again.
I only hope that I was of some help. I don't think for example that let's say one ST's engineer or executive if he/she was to have some medical examination with an ECG or Ultrasound device would deny to take it knowing that the μCs and DSPs inside that medical device are from TI. Isn't it so? Am I right?
John

John - in general "Yes" unless of course the µC was an LM3S...

My (early) conclusion is that (others) arriving here may "better deploy" your links than the originating poster. (earlier posts here describe that sense...)
