Notes for Teacup:
|
|
|
|
Copied from $(MBED)/libraries/mbed/common/pinmap_common.c.
|
|
|
|
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.
|
|
- Wrapped the whole file in #ifdef __ARMEL__ to not cause conflicts with
|
|
AVR builds.
