Applications
Applications for the mbed platform can be developed using the mbed online IDE, a free online code editor and compiler. Only a web browser needs to be installed on the local PC, since a project is compiled on the cloud, i.e. on a remote server, using the ARMCC C/C++ compiler. The mbed IDE provides private workspaces with ability to import, export, and share code with distributed Mercurial version control, and it can be used also for code documentation generation. Applications can be developed also with other development environments such as Keil µVision, IAR Embedded Workbench, and Eclipse with GCC ARM Embedded tools.
SDK
The mbed software development kit (SDK) provides the mbed C/C++ software platform and tools for creating microcontroller firmware that runs on smart devices. It consists of the core libraries that provide the microcontroller peripheral drivers, networking, RTOS and runtime environment, build tools and test and debug scripts.
A components database provides driver libraries for components and services that can be connected to the microcontrollers to build a final product.
Demo-boards
There are various hardware demo-boards for the mbed platform, with the first being the original mbed Microcontroller board. The mbed Microcontroller Board (marketed as the "mbed NXP LPC1768") is a demo-board based on an NXP microcontroller, which has an ARM Cortex M3 core, running at 96 MHz, with 512 KB flash, 64 KB RAM, as well as several interfaces including Ethernet, USB Device, CAN, SPI, I²C and other I/O. The mbed microcontroller received first prize in the annual EDN Innovation Awards' Software/Embedded Tools category in 2010.
Various versions of the board were released, with NXP LPC2368 (ARM7TDMI-S), NXP LPC1768 (Cortex-M3), NXP LPC11U24 (Cortex-M0) microcontrollers.
HDK
The mbed hardware development kit (HDK) is designed for OEMs, and provides information to build custom hardware to support the mbed SDK. This consists of interface firmware and schematics that can be used to easily create development boards, OEM modules and re-programmable products suitable for production.
Project development
The project is developed by ARM in conjunction with other major technology companies and the mbed developer community. Development and contributions happen at different levels:
