[En-Nut-Discussion] NutGpio Api and Multidrive for AVR

[Ole Reinhardt]

Hi Uwe,

unfortunately I did not really understand the functionality of your
enhanced GPIO API functions "NutGpioPinDrive()" and
"NutGpioPinRelease()"

Could you explaint them a little more in detail?

> The last NutGpioPinSetHig makes sure the AVR pullup turns on the internal
> pullup. For non-AVR architectures, NutGpioPinSetLow(...)  and
> NutGpioPinDrive(...) are empty function in most cases

Is this just a typo or do you really mean that NutGpioPinSetLow() is an
empty function in most cases? If so, why?

I just have concerns that we might have different understanding of what
the function shall do on different architectures and will just prevent
to get some incompatibilities there.

Best regards,

Ole
