Trends for Devices Devices are complementary to desktop and web applications

Devices are more and more connected and intelligent

Devices require a fast time-to-market turnaround

Fast growing business for 32 bits MCU/MPU

Highly innovative market

Trends for Devices Application fields are diverse and require specific hardware programming skills

Connectivity must address peer devices, desktop and services transparently

Very diverse toolset, no standard programming model

Few standard communication protocols and little support

Code is generally difficult to port

Agenda- What is the .NET Micro Framework (aka .NET MF or MF)- How the MF bridges embedded and desktop programming- Architecture- Demo- Tool set and programming model - The latest version - Distribution and community - Getting started

MCU Example: ARM7 / Cortex-M3 / SH2 ARM9 / Cortex-A8 ARM11 / Cortex-A9 / Atom Centrino

The .NET Micro FrameworkThe .NET Micro Framework is a re-implementation of the desktop CLR for embedded devices that are unable to run a high-end embedded OS such as WinCE

Very small memory footprint: • Completely modularized by feature • 512KB ROM / 256KB RAM for the full feature set • WinCE and CF may require more than 10MB ROM / 10MB

RAM

Typical price point of the MCU between $2 and $10

Supports all ARM MCU from ARM7 and up, Analog Devices Blackfin and Renesas SH2/SH2A MCU. No MMU restrictions

Entirely independent code base: this is not the Compact Framework

Bridging the Gap with Desktop Programming The programming model is entirely managed codeThe programming environment is the latest VS2008 SP1Interoperability is supported Object Model offers a sub-set of the same namespaces of the .NET Framework for the desktop Object Model is tailored for small embedded devices

.NET Micro Framework SDKContains everything you need to get started!

- Add-in installer for the latest VS 2008 SP1 - Post-processing of assemblies into the .NET MF compact format- Project wizards - Full .NET MF object model - Standard emulator - Deployment and debugging against the emulator or any device- Samples - Font editor tools - Device Diagnostic tools - Help (also available online at MSDN) - Compatible with VS2008 Express Edition

.NET Micro Framework Porting KitContains everything you need to port the MF onto any device! With the Porting Kit you have full source code access to:

• Code and build device drivers for the .NET MF • Code interoperability components and expose them to the

OM • Customize the runtime and object model for special needs• Add support for additional instruction sets

Assisted creation of new drivers and processor support packages

Supports mainstream embedded tool chains such as ARM RVDS, Keil MDK, GCC, HEW, Visual DSP++

Includes extensive sample libraries coded by silicon vendors such as Atmel and NXP for mainstream MCUs

DistributionThe v4.0 version changes the business model from the ground up

As of 11/16/2009 the .NET Micro Framework version is available as source code under the Apache 2.0 license

All the code of the runtime, the object model and device drivers is available free of charge

TCP/IP stack code is provided under the restriction that it must be used in conjunction with MF only

Crypto code is pre-compiled for the supported instruction sets, but replaceable

CommunityIdeal for both professionals and hobbyists Co-operative development inside the communityMicrosoft will oversee and approve the feature set together with the community leaders Community Web for exchanging components and solutions Microsoft will officially support any latest version of the .NET MFAnybody is welcome to participate to whatever extent, contributions are encouraged but not required

RTM date: Yesterday!

RoadmapVersion 4.1 is tentatively scheduled for End of Third Quarter 2010 (March 2010)

Priorities: • Keep release in sync with Visual Studio 2010 support • Big Endian Support • Open TCP/IP stack• Extensive Cryptographic support • 802.15.4 (with 6lowPAN) and 802.11 drivers • Remote Firmware Update • Remote logging and diagnostics

ResourcesThe .NET Micro Framework eco-system relies on a network of partners

Partners own reference hardware, ports, library extensions and specific solutions

Many reference ports are published and documented in the Porting Kit and provided free of change

Atmel and NXP substantially contributed to the PK reference ports

Some partners can also assist developing custom solutions, independently or in conjunction with the .NET Micro Framework team
