Notes for Teacup:
|
||||
|
||||
Copied from $(MBED)/libraries/mbed/hal/pinmap.h.
|
||||
|
||||
Used only to get things running quickly. Without serial it's almost
|
||||
impossible to see wether code changes work. Should go away soon, because
|
||||
all this MBED stuff is too bloated for Teacup's purposes.
|
||||
|
||||
- Prefixed names of #include files with mbed- to match the names of the
|
||||
copies in the Teacup repo.
