Open Community ARMmbed
It 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.
ARMmbed 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.
- http://wiznetmuseum.com/portfolio-items/what-is-mbed/?portfolioID=19781
- https://www.mbed.com/en/about-mbed/what-mbed/
Refer to these links if you would like to find out more about the 100 platforms, 400 components, and 20,000 codes.
- Platform : https://developer.mbed.org/platforms/
- Components : https://developer.mbed.org/components/
- Code : https://developer.mbed.org/code/
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.
- https://developer.mbed.org/handbook/mbed-Compiler
- http://wiznetmuseum.com/portfolio-items/how-to-use-mbed-web-ide/
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
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.
This post will introduce a few of IoT cloud services from the WIZnet Museum.
1. IC2Cloud: www.ic2cloud.com
http://wiznetmuseum.com/portfolio-items/www-ic2cloud-com/
IC2Cloud is one of the easiest cloud service I experienced. The most powerful advantage of IC2Cloud is programming the server by using drag-amd-drop ICON such as App inventor. It is also specialized for IoT projects; there are 8 examples of Arduino uploaded on WIZnet Museum.
2. IBM Bluemix: Build a cloud-ready temperature sensor with the Arduino Uno and the IBM Watson IoT Platform
This project used bluemix cloud from IBM. It shows data in real-time graph after sending temperature data as MQTT protocol to IoT foundation server of Bluemix using Arduino and Ethernet Shield. MQTT is a typical IoT protocol made by IBM and used for Facebook chat.
3. Dweet.io: Send data to dweet.io and freeboard.io
http://wiznetmuseum.com/portfolio-items/send-data-to-dweet-io/
This project used cloud platforms such as Dweet.io and Freeboard.io . It collects data through Dweet.io and shows the form that users want using Freeboard.io. Arduino and Ethernet Shield were used to implement this IoT device.
4. Cloud MQTT: How to implement embedded Mqtt Client using W5500 IC
http://wiznetmuseum.com/portfolio-items/how-to-implement-embedded-mqtt-client-using-w5500-ic/
This project explained how to implement MQTT Client in W5500 custom board. For explanation, an exclusive cloud platform for MQTT called Cloud MQTT was introduced; it is made by using AWS cloud service and there is no need to implement MQTT Broker.
5. ThingSpeak: Logging Data and Displaying Graphs over the Internet with Arduino
This project introduced an IoT cloud service called ThingSpeak. It shows sent data using Arduino and Ethernet Shield in graphs and seems to be appropriate for beginners.
There are only 5 IoT cloud projects introduced in this post, but please visit WIZnet Museum for more info of IoT cloud projects.
Wiznet Museum site: http://wiznetmuseum.com/
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.
Visitor Tracking via Wi-Fi
Wi-Fi Probe request is used to actively seek any, or a particular access point.
For example, if you turn on the Wi-Fi of the smart phone, the smart phone will show all available AP list. At this time, the smart phone transmits the “Probe Request” packets to search the APs around. After then the phone will show a list of APs that sends the response packets to the phone.
The probe request packet includes MAC address information of the device. Therefore, if we can capture this probe request packet in any specific area, it is possible to collect the data about staying time of devices. In this posting, we will make a device to track Wi-Fi devices using probe request packets.
<Hardware>
We need below hardware
- WIZwiki-W7500 (ARM Cortex-M0 Platform)
- WizFi310 : Wi-Fi Module (This module has the function to capture the probe-request packet.)
- SD CARD
WizFi310 scans the probe request around and send the data to WIZwiki-W7500ECO. After parsing the data, WIZwiki-W7500 save the data in the SD Card.
The source code for this operation, can be downloadable from mbed.
https://developer.mbed.org/users/jehoon/code/WiFi_Tracker/
<Result>
We could get the below data.
- X4000 : Probe request packet
- xx:xx:xx ~~ : MAC Address
- -84:RSSI (Wireless Signal Sensitivity)
By analyzing above raw data, we could get below result
- WizFi310 captured about 36,000 Probe request packets
- Found 343 MAC addresses
- Captured 15,000 probe requests from a MAC address
- Captured more than 1000 probe requests from 5 MAC addresses
- Captured more than 100 probe requests from 33 address
If we use this ‘probe request packet capture’ function, we may be able to make the device to search the visitors who often visit a specific area and sends various information such as restaurant, movies, parking places and etc.
IoT Pet Feeder
If you have this ‘IoT Pet Feeder’, you can feed your pet on command from anywhere in the world and monitor them if they are O.K without any problem.
In this posting, we will introduce the initial version of a pet feeder. The author will develop this device by adding more functions such as Wi-Fi, network camera and etc.
As you see above image, a rotating typed servo motor is installed in the T-PVC with auger screws. The servo motor is controlled by the WIZwiki-W7500 platform. By implementing web server , you can remotely control the device from a web page. If you click below image, you can learn more about WIZwiki-W7500 (ARM cortex-M0 MCU platform board)
For the case, the author used various material. He made some parts by using 3D printer. If you go to the Thingivers site, you can easily find the 3D modeling files for pet feeder. For this project, he used the files from below link.
http://www.thingiverse.com/thing:34100
We also need the T type PVC.
To save the cost, he used the pack of the Pringles.
Below is the servo motor image (Parallel Continuous Rotation Servo)
Now, let’s assemble them. When he printed the auger screw using above 3D modeling file, he found its size does not fit into the T-PVC. So he cut one side of the PVC.
It is not difficult to assemble the all the parts. He made the cap for the feeder with the Pringle cap. In the 0.1 version, as the network connection is implemented by Ethernet, you can see the network lines. In the next version, the Wi-Fi and network camera will be added.
As the web server is loaded on WIZwiki-W7500, you can control the device on the web page. If you click the “Network Information” menu, you can configure the network parameters for the device. The “Feeding Example” will provide the menus for motor control (Left/Light Control & Go/Stop Control) When the camera is installed to this device, you can monitor your pet through “Monitoring Example” menu.
All the codes are programed by mbed on-line compiler. If you go to below page, you can download the all source code.
