Arduino vs. Mbed

[oclyke]

related to issues #342 and #333

the subject is: why support the Arduino API when we have Mbed?*

@jerabaul29 and @idea--list have brought up some interesting discussions about the power of modern C++ standards and the uniformity + documentation of Mbed.

My opinion on all this: we support Arduino as yet another abstraction. It was, and still is, a popular and approachable way for people to get into embedded programming. As users become more advanced they may outgrow Arduino and move on to using other tools such as:

AmbiqSuiteSDK - raw C/C++ SDK for Apollo3 with Hardware Abstraction Layer (HAL)
Arm Mbed - embedded RTOS with support for Apollo3 (we want community engagement here to help keep the support up-to-date of course!)

We stick with Arduino standards in this Arduino core because, after all, that is the purpose of this core.
