Francisco J. Manno 36b759e801 Fix gcc [-Wsign-compare] warning 
[Warning] mbed_board.c@99,36: comparison between signed and unsigned
integer expressions [-Wsign-compare] is seen during compilation.
Fix the warning and small improvements.

1. Change type of loop variable "i" to the same type as "size".
   Size is > 0 checked by the if statement and i stops at == size
   so none can be negative. However size still needs to be signed
   to detect error codes from vsnprintf.
2. Reduced scope of stdio_out_prev and make sure it's initialized.
3. Define a name for the error buffer size and use vsnprintf instead
   of vsprintf to avoid writing outside of the array.
   NOTE: the if(size > 0) statement doesn't need to change. If
   the message to write is larger than the buffer size vsnprintf
   truncates it automatically but still returns a positive value.

ARM mbed OS

mbed OS is an open-source embedded operating system designed specifically for the "things" in the Internet of Things (IoT). It includes all the features you need to develop a connected product based on an ARM Cortex-M microcontroller.

mbed OS accelerates the process of creating a connected product by providing a platform operating system that includes robust security foundations, standards based communication capabilities, built-in cloud management services, and drivers for sensors, I/O devices and connectivity. mbed OS is built as a modular, configurable software stack so that you can readily customize it to the device you're developing for, and reduce memory requirements by excluding unnecessary software components.

Current release

The current release, along with a selection of previous versions are detailed here: Release Notes

Getting Started for Developers

Please note that you will require mbed CLI to build mbed OS. For more details, please read the getting started guide for developers using mbed OS in applications:
