Kevin Bracey 866b669d6e Add Kernel::get_ms_count 
Give C++ access to the RTOS's absolute timebase, reducing the need to
run private Timers and similar. Allows wait_until functionality, and
makes it easier to avoid time drift.

Place it in a new header and namespace in case we want more kernel
functions in future.

Try to cover over the breaking API change potentially upcoming in
CMSIS-RTOS 2.1.1, when it reduces the tick count from 64-bit to 32-bit.
(See https://github.com/ARM-software/CMSIS_5/issues/277)

Explicitly state that ticks are milliseconds in mbed OS, despite CMSIS
RTOS 2 permitting different tick rates.

See also https://github.com/ARMmbed/mbed-os/pull/3648 (wait_until
for condition variables) and
https://github.com/ARMmbed/mbed-os/issues/5378 (EventQueue should
use RTOS tick count).

Mbed OS

Build status release Build status master Tools coverage status PR progress

Arm Mbed OS is an open source embedded operating system designed specifically for the "things" in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices.

Mbed OS provides a platform that includes:

  • Security foundations.
  • Cloud management services.
  • Drivers for sensors, I/O devices and connectivity.

Release notes

The release notes detail the current release. You can also find information about previous versions.

Getting started for developers

We have a developer website for asking questions, engaging with others, finding information on boards and components, using an online IDE and compiler, reading the documentation and learning about what's new and what's coming next in Mbed OS.

Getting started for contributors

We also have a contributing and publishing guide that covers licensing, contributor agreements and style guidelines.
