how to use 'owalt' pin in '1-wire' for tm4c129xnczad?

Hello Eagle,

Wouldn't this be a better question to ask of your CAD tool vendor? Or am I misunderstanding your question?

@Chuck,

Firm's/my thought - exactly. Poster's brevity confounds - while, "much obliged" he has not, (more importantly) "much explained/detailed!"

Hello Jin,

As you can see in the application note, only one wire is needed

The OWALT is not required for most applications. Only when using high drive (when supported by the slave device), OWALT is used and it requires the use of a MOSFET.
