@ -130,12 +130,6 @@ This is an example on how to define UART names in PinNames.h:
Note this document is proposing unifying the pin names used for UART communication between the MCU and the host PC.
Note Mbed OS expects to use these names internally (a fix might be needed during the implementation), for example:
mbed-os/platform/source/mbed_retarget.cpp
mbed-os/hal/static_pinmap.h
mbed-os/hal/mbed_pinmap_default.cpp
### Non-valid definitions
If either LEDs or buttons are not available, they should not be defined.
