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

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

The .NET Micro Framework

The .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 code

The programming environment is the latest VS2008 SP1

Interoperability 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 SDK

Contains 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 Kit

Contains 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

The Programming ModelManaged Code Device Drivers, abstracted I/O and virtualized input for maximum portability

Encourages event based programming and provides advanced sleep-on-HW-event support for maximum battery life

public static class BatterySaver { public static void WaitOnSerialInput( SerialPort sp ) { sp.DataReceived += new SerialDataReceivedEventHandler( this.DataOnSerial ); PowerState.Sleep(SleepLevel.DeepSleep, HardwareEvent.SerialIn); }

private static void DataOnSerial(object sender, SerialDataReceivedEventArgs e) { … ((SerialPort)sender).Read(...); ... } }

Communication and Messaging

HTTP(s)• HttpWebRequest, HttpWebResponse and HttpListener• Supports HTTP/1.1 with chunking and keep-alive• Supports SSL with X.509 certificates

DPWS• Supports WSDL 1.1, SOAP 1.2, WS-Addressing, WS-

MetadataExchange, WS-Transfer, WS-Discovery, WS-Eventing • Compatible with WCF Soap bindings • Code generation tools to/from WSDL and assembly • Code generation compatible and interoperable with desktop

tools

Wired and Wireless• Ethernet, Serial and USB • 802.11 configuration support • 802.15.4 stack available (not yet documented)

UI Support

Inspired to WPF, supports dynamic layout, rendering , and event dispatching

Basic types• Application• Windows

Basic layout controls• StackPanel • Canvas • InkCanvas

Basic controls• Text• ScrollViewer• ListBox

Event routing and input providers support

Integrated Touch Panel and Inking support

Distribution

The 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

Community

Ideal for both professionals and hobbyists

Co-operative development inside the community

Microsoft 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 MF

Anybody is welcome to participate to whatever extent, contributions are encouraged but not required

Additions for the 4.0 version

HTTP(S) Versioning Faster XML parser and System.Collections supportFaster Graphic/Touch/Inking support Power Level control Wear Leveling for Block storage devices Time SyncArbitrary Display Size Support for Atmel AT91SAM9RL64 ARM9 processor Support for NXP LPC2478 AR7 processorRenesas SH2/A support for SH7619

RTM date: Yesterday!

Roadmap

Version 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

Resources

The .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
