TM4C132G to TM4C129 code portability

If I may on this "US Thanksgiving day" (Amit relaxed) forum I'll answer "generally" yes - but "entirely the same API" no!

Be especially observant of different:

• System Clock functions
• I2C functions (these are especially (dreadful) and include a "double read" to insure that a key/critical bit has toggled
• as a non TM4C129 user (we use another's far faster M4 MCU) you should note that not all functions pass in their entirety.   I'm unable to id these - but have alerted you

Thus - the switch-over will not be "automatic" (i.e. w/eyes closed) but w/"reasonable" scrutiny on your part - should be far faster/easier than, "Starting from scratch."   And your title "TM4C132" (should) be edited/corrected.    While clearly "typo" - it's not a good reflection upon one's,  "Attention to detail" (required by your stated objective.)

Hello Peter,

The Migration Application Note will be rather useful from both HW and API perspective.

Hi Amit,

Indeed - such a focused note proves of very high value.  

Yet - (and continuing) poster appears (completely) unaware of such a valued note.    (and I had forgotten its availability)

Does this not speak to (again) FAR BETTER Promotion of such key/vital/helpful documents - which (far too often) are completely missed by posters?  (and certain semi-regulars) 

Of course you do not "Make the Rules" - yet "how many times must the 2x4 land" before the methods/madness are (properly) recognized - and altered?

Hello cb1

Yes. And this has been an issue on how information is really looked at. As an example when we "google" for specific topic, we hardly go past 3-4 search pages before re-entering the data. The information overload is to be balanced with information dissemination and means to embed this in forum is a debated topic.

Hi Amit,  

But why - w/a web-site the size & might of yours - must we, "google?"

And why - must we (move) from Forum Home Page. (i.e. right here?) 

Can anyone justify (why) "Blogs, Groups & Videos" receive, "TOP of this Forum, RED-STRIPE Promotion - while ALL "key/critical" App Notes, White Papers, Tech Manuals are "buried" elsewhere?    Thus requiring much (unwanted/unnecessary) extra time & effort to search and (maybe) discover!

How can this require ANY debate?   Really?  

Substantial "free Red Space" remains atop this Forum - welcoming key/critical App Notes, White Papers, MCU Manuals etc.

Repeating this (present) "Clearly Wrong Way" (i.e. bury, hide, obscure) is unlikely to: "Boost MCU Sales - strengthen user allegiance - and avoid (needless) forum repetition!"

Hello cb1

The "google" was an example I had used to explain my point.

Regards
Amit

You know that many here (especially moi) honor & respect you.    As always - (even for one w/your talents) it proves difficult to, "Defend the Indefensible."  

That "free Red Space" perched (strategically) atop this very Forum Page - proves ideal for such "Valuable, MCU-critical Data" does it not?   (of course it does!)

Yet "Blogs, Groups & Videos" rule that space - along with a huge amount of, "empty" white (red) space.   Google is a smoke-screen - free Red Space is so obvious - even poster cb1 can see it!   

Hello cb1,

While hard to miss, the key words would be useful for forum member to relate to what they are looking for. How do I know that a migration guide is under Application Note in the first place. Rather a long debate to start.

Regards
Amit

My friend Amit - there's room (up top) for, "Blogs, Groups, Videos" - surely "Key/Critical MCU Data" (highly sought) could fit.   I've been here since LMI days (firm which developed "Stellaris" - later acquired by T.I.) and such "necessary tech data" USED to reside, "up top - in highlight - for quick, easy, user recognition!"   And that worked GREAT! 

And now - ALL of that vital data has been BANISHED!   Few know where!    And - largely unwanted, "Blogs, Groups, Videos" occupy that, "prime, beach-front" real estate!   As shown (below) much area is available (and inviting) for NECESSARY MCU Data - not the (fluff) there now...

And Amit - can you (ever) recall any poster requesting (anything) regarding, "Blogs or Groups" - staff/I cannot!   Surely, "App Notes, MCU Data, LPad/Eval Kits & Migration" would FIT w/in that "Hot/Top" attention-grabbing Red Zone!  (presently, "significantly wasted" by low-priority, low-interest, "Blogs/Groups" etc.)

Really Amit - there's no debate - and surely no (long) one!   Is not your specific reference to, "Migration" (really) a "straw-man" type of argument?    No method can (ever) quickly/easily & instantly - identify everything!   (that's the straw-man - the "real issue" is the improvement which Red Zone Promotion clearly provides!)  

Launching most (all) searches from your vital forum resource is far more intuitive - logical - faster - and much more effective - than forcing your users AWAY!   (to search blindly - where they may encounter, "more easily found" competitve offerings.)

Few (maybe none) here really care about "Blogs/Groups" - forcing your user-clients (away) from your main forum "Info Central" makes NO Sense!

Hello cb1,

I do understand your point and I would make the recommendation and to an extent try to push for the change as well.

Regards
Amit

Hi Amit,

This is NOT (my) point - it is a "summation" of the cries, requests, (even) pleadings of MANY "hapless Forum Users" who KNOW that T.I. can do better!   (Amit you know that my firm serves multiple clients here - I "PM" w/ many forum users - and speak/deal w/key clients on a (near) daily basis!)

How, "Blogs, Groups & Videos" have been promoted (above) far more vital, "MCU manuals, App Notes (I'm told a NEW Boot-Loader one is GREAT!), LPad/Eval Kits and (even) MCU Migration" escapes our understanding.   And - most likely - escapes any justification.

You don't make these rules - someone does - and, "Is it not - a (big) person, who can, "Steer Titanic from the Iceberg?"

Hello cb1,

If I were to sum up the "Red Bar", it would rather look like "User Guides", "Application Notes", "Resources".

User Guide: Covering the documentation of LaunchPad and EVM's
Application Note: Covering what we are trying to do...
Resources: Covering MCU Migration Guide, Debugging Common Issues, Handling Bus Faults, JTAG....

Regards
Amit

Hi Amit,

That's great - an excellent beginning - can easily be "tweaked" as conditions/usage dictate - and meets the (obvious) goal of, "Launch key/critical, TM4C searches from TM4C's Terrific Forum!   (i.e. your forum)

And - if and when - that Red Bar (properly) extends to include "valued, highly sought info" - staff/I will make the supreme sacrifice - and click on "Blogs."  (while holding our nose - and (likely) - just once...)
