undefined reference digitalPinToPinName with mbed@2.5.2

[rajames]

Using mbed_nano@2.5.2 I get the following build errors:

any idea when this can be merged?

@rajames that include shouldn't be used by libraries since it's not part of the APIs and in fact the error you get is arising from some kind of non standard compilation process. If you compile with normal arduino IDE / CLI and core 2.5.2 it will finish cleanly. I can help sorting out the "original" issue though 😉
