Open Community ARMmbed

Arduino LogoIt has already been a decade since Arduino was first introduced to the world. And since 2005, terms like open source hardware and software, have been used more commonly.

Nowadays, students can also implement their ideas into reality using Arduino; and the communities based on open source hardware and software have enabled it.

The number of makers using Arduino grows every second and communities made by makers play a powerful role in the era of IoT. The potential of IoT just seem endless thanks to Arduino.

 

To follow the trend of open source hardware, ARM corporation provided an alternative option beside Arduino with ARMmbed. ARMmbed provides an ecosystem in collaboration with many silicon partners, cloud partners, and device partners; ARM says that any developer can easily develop an IoT device platform and prototype using platforms and services provided in the ecosystem. ARMmbed expects to become the ecosystem that can lead the IoT era.

20160711_103929ARMmbed first launched its beta version in 2009. Since then, ARMmbe built its ecosystem by collaborating with other IT companies like Atmel, NXP, Nordic, and STM. Almost 100 platforms based on Cortex-M series core were registered and around 400 components were used in that platform, resulting in creating over 17,000 projects and 6,000 libraries currently opened and registered. Also, mbed OS is slowly being considered as the most powerful OS in IoT device market since ARM was famous for developing CPU architecture.

However, mbed has not built a large fandom as Arduino so far although it has successfully made and provided an ideal environment. This post can help developers and makers who have not experienceed or underutilized ARMmbed.

Refer to these links for more details about ARMmbed.

Refer to these links if you would like to find out more about the 100 platforms, 400 components, and 20,000 codes.

 

Be aware that the ARMmbed ecosystem is an environment created by its users. Users made and shared more than 20,000 codes, thus there could be errors and difference in the implementation content. However, these difficulties are commonly found when obtaining info from the open source communities. Since ARMmbed ecosystem provides service simlir to Git, which many developers use, users can obtain the shared code and modify projects or libraries already created and send comments to ther users; and through these activities the code becomes more reliable.

One of the strengths of the ARMmbed ecosystem is the Web Compiler developed by ARMmbed.
ARMmbed brought the working environment for developers from Local to Web using this Web Compiler. This allows users to open and share many projects and libraries. And the data that developers use with platforms provided form ARMmbed, are currently being strored in the ARMmbed database through the Web compiler. As result, ARMmbed has been able to secure powerful resources of open source software in a short period of time.

The Web Compiler provides many advantages to the ARMmbed ecosystem and its developers, and one of those advantages is version management. Web Compiler enables easy version management since it provides simliar service as Git. Users can use and switch among the registered 100 platforms and easily compare with previous versions when working as a team.

The following links explain how to generate and compile projects on Web Compiler.

 

Lastly, the picture and link below is about the product development procedure in the ARMmbed ecosystem.

I will introduce various projects made with WIZwiki-W7500 platform board from WIZnet, Silicon partner of ARMmbed, in the next curation.

IoT Cloud Service

network-782707_960_720

There seems to be a lot of excitement about IoT these days. Gartner forecasts IoT devices would increase to 25 billion pieces in 2020 from 4.9 billion pieces in 2015. The industry will increase at least 5 times during the next 5 years. Although negative evaluation such as exaggerative advertisement of IoT exists, the fact is that the number of IoT device is sharply increasing at a fast phase. And if the number of IoT device increse, related service also increases. These related servicees will collect huge amounts of data and share the data with users after analysis. The capacity of server that handles IoT service should be in a state of flux depending on the amount of data collected if we consider the number of IoT device increased sharply. IoT service will also rapidly change since it is at an early stage. Then, the server program should be very flexible and IoT services require all levels of IT from “embedded” to “server”. Do you think this will require high technology? It does not. Cloud service meets all requirements; it can change capacity depending on the amount of data and its pricing and server programs are very flexible. Another advantage of cloud service is that users can drive its server by simply drawing a diagram instead of programming it.

So which companies lead the cloud service? Global companies provide cloud service such as Google cloud platform from Google, aws from Amazon, and azure from Microsoft. Besides that, there are endless companies providing cloud service.

Even though the usage of clouds for IoT these days is already widely used, more IoT cloud platforms will become available because of its usefulness.

If you are planning a business that provides IoT service, I suggest you wisely choose the right cloud server, service, or platform for your application.

Starter Kit: InternetOfThings

The Internet of Things is an evolution of the Internet. It interconnects not only human and computer as before but also physical objects (things).

starter kit

The Starter Kit: Internet of Things offers an easy access into the world of the Internet of Things. It allows to control many devices over the Internet. For that the kit is equipped with a Remote Switch Bricklet. It can be used to remotely control 433MHz mains switches, dimmers and home automation components. You can find a list of supported actuators in the documentation of the Bricklet.

With the API Bindings it is possible to control the wireless actuators with any (Embedded-)PC, smart phone or tablet over the Internet.

With the kit nothing stands in the way of turning your coffee maker on while you are heading home or to dim your living room illumination with your own cloud or with a Raspberry Pi. The website http://www.iot-remote.com gives you direct access to wireless actuators from any web-enabled device.

starter kit inside

The kit basically consists of a Master Brick and a Remote Switch Bricklet which is equipped with a 433MHz transceiver. Over the USB connection of the Master Brick you can control remote control mains switches or similar. An (Embedded-)PC (e.g. Raspberry Pi) either does the switching itself or it can serve as a gateway. With an additional Ethernet Master Extension it is possible to go without a gateway.

With additional modules from the Tinkerforge building blocks you can extend the kit. It is for example possible to measure temperature (Temperature, Temperature IR or PTC Bricklet) or to react on movements (Motion Detector Bricklet).
