what pin is AIN0 on? PE3 or PE7?

Might your reveal of the MCU in question assist?

I am sorry. it's the TM4C129xnczad.

Ok - and of course firm/I use only 4C123.

When in doubt "ALWAYS" observe the MCU's datasheet. Software examples surely "pre-existed" your MCU - thus (most always) prove suspect.

Your MCU datasheet will properly guide you.

It's shows the same on the 4c123. PE3 is AIN0. But, all the examples I have found in the Tivaware show PE7 and AIN0.I will do some code and found out which one, but I would be nice to document the error if there is one.

My friend - I understand your quandary - yet as stated - those ADC examples were (most likely) created LONG BEFORE TM4C12x "saw the light of day." This vendor - and others - cannot adjust ALL Past Examples to accommodate every new MCU - can they?

It is extremely unlikely for the datasheet to lie - creating a "universal example" - good for EACH/EVERY MCU this vendor introduces - is not a realistic expectation.

Your datasheet holds your answer - w/out fail!

Thank You. I will trust in the datasheet. For if we can't find the answers in the datasheet, we are surely lost.... ;)

The datasheet - some experimentation (as you yourself mentioned) and "selective adapting of past examples to your current MCU" should prove, "Best Path." You're on your way - bon chance, mon ami... (remember - most all examples were created LONG prior to the birth of your MCU! [it's this vendor's latest/greatest...and aging (gracefully)]

Hello Jerry,

Will need to file a bug to ensure this issue is fixed.

Indeed Dave - you are correct - again.
The world (surely) awaits an M7 armed w/multiple (still unneeded/unwanted) NMI defaults - and an eval board w/GPIO to GPIO (dead shorting) plague-istors" (to maintain (backwards) compatibility...)
