WIZnet Distinctive Excellence IoT Projects

The Circuit Cellar team felt strongly that there were considerably more first-rate projects entered in WIZnet Connect the Magic 2014 Design Challenge than could be satisfied with the available prizes. Thus, it designated a special category called “Distinctive Excellence” for some of the more interesting projects. The Distinctive Excellence projects are now live on the challenge website.wiznetDEs

DIY Network-Ready Polyphonic Music Controller

Hans Peter Portner’s Chimaera project is a touch-less, expressive, network-ready, polyphonic music controller released as open source hardware. It is a mixed analog/digital offspring of the Theremin. An array of analog, linear Hall effect sensors make up a continuous 2-D interaction space. The sensors are excited with Neodymium magnets worn on fingers.

The device continuously tracks and interpolates position and vicinity of multiple present magnets along the sensor array to produce corresponding low-latency event signals. Those are encoded as Open Sound Control bundles and transmitted via UDP/TCP to a software synthesizer. The DSP unit is a mixed-signal board and handles sensor read out, event detection and host communication. It is based on an ARM Cortex M4 microcontroller in combination with WIZnet W5500 chip, which takes care of all low-level networking protocols via UDP/TCP.

First Prize — Chimaera: The Poly-Magneto-Phonic Theremin, Hans Peter Portner (Switzerland)

The poly-magneto-phonic Theremin

In his project write-up, Portner explains:

With its touch-less control (no friction), high update rates (2-4 kHz), its quasi-continuous spatial resolution and its low-latency (<1 ms), the Chimaera can react to most subtle motions instantaneously and allows for a highly dynamic and expressive play. Its open source design additionally gives the user all possibilities to further tune hardware and firmware to his or her needs. The Chimaera is network-oriented and configured with and communicated by Open Sound Control, which makes it straight-forward to integrate into any setup.

The hardware of the Chimaera consists of two types of printed circuit boards and an enclosure. Multiple sensor units are daisy-chained to form the sensor array and connected to a single digital signal processing (DSP) unit.

A single sensor unit consists of 16 linear hall-effect sensors spaced 5mm apart and routed to a single output through a 16:1 multiplexer which is switched by the DSP unit. Downstream the multiplexer, the analog signal runs through an amplification circuitry.

A modular hardware design consisting of identical sensor units and a single DSP unit embedded in a wooden case allows building devices with array sizes of 16-160 sensors.

The DSP unit is a mixed-signal board and handles sensor read out, event detection and host communication. It is based on an STM32F303Cx ARM Cortex M4 microcontroller in combination with WIZnet W5500, a hardwired 100Mbit IPv4/PHY chip taking care of all low-level networking protocols via UDP/TCP. The board’s analog part features 10 analog inputs providing connection points for the sensor units, leading to a maximally possible array of 160 sensors. Those analog inputs connect directly to three in parallel running 12bit analog-to-digital converters.

Networking technology in a zero configuration setup has advantages in respect to long-distance transmission, operating system independence and inherent ability for network performances. We thus use the Open Sound Control (OSC) specification via UDP/TCP as low-level communication layer.

DIY IoT: Build a ‘Net-Connected System Today

It’s time to join the Internet of Things (IoT) revolution. Try building a ‘Net-enabled design with WIZnet’s W5500 “smart” Ethernet chip. It’s easier than you think.

In a thorough introduction to the technology, Tom Cantrell presented a garage door monitoring design. He explained:

The W5500 (see Figure 1) starts with a standard 10/100 Ethernet interface (i.e., MAC and PHY) but then goes further with large RAM buffers (16-KB transmit and 16-KB receive) and hardware TCP/IP protocol processing. I discovered WIZnet’s first chip, the  W3100, way back in 2001. Of course by now, as with all things  silicon, the new W5500 is better, faster, and  lower cost. But the concept is still exactly  the same: “Internet enable” applications by  handling the network chores in hardware so  the application microcontroller doesn’t have to do it in software.

Cantrell - WIZ550io

Figure 1: The WIZnet W5500 is an Ethernet chip with a difference—large RAM buffers and hardware TCP/IP processing that make it easy for any microcontroller to go online.

The large RAM buffers help decouple the  microcontroller from network activity. In a  recent project (see my article, “Weatherize  Your Embedded App,” Circuit Cellar 273,  2013), I used the RAM to receive an entire  10-KB+ webpage, completely eliminating the  need for the microcontroller to juggle data at  network speed. And any of the 32-KB on-chip  RAM that isn’t needed for network buffering  is free for general-purpose use, a big plus for  typically RAM-constrained microcontrollers. The other major WIZnet hardware assist  is TCP/IP processing using IP addresses, sockets, and familiar commands including OPEN, CONNECT, SEND, RECEIVE, DISCONNECT.  The high-level interface to the network frees  up microcontroller cycles and code space that  would otherwise be needed for a software TCP/IP stack.

Cantrell goes on to present his design for a ‘Net-connected garage door monitoring system.

For prototyping, check out the WIZnet  ioShield (see Photo 1), which is a baseboard  for the WIZ550io that includes an SD card  socket. There are ioShields for different  platforms (e.g., Arduino, LaunchPad,  mbed, etc.), and with 0.1” headers they are  breadboard friendly.

Photo 1: If you want a fancy server with lots of eye candy, a microSD card is the way to go. The WIZnet ioShields include the card socket and are available for various platforms. The Arduino version is shown here.

Cantrell prototyped a client version of what he calls his “garage  door ‘Thing’ using an Arduino  and a WIZ550io connected to Exosite (see Photo 2).

A prototype of the client version of my garage “Thing” is shown.

Photo 2: A prototype of the client version of my garage “Thing”

Wondering how to get two clients (e.g., ) to interact with each other? Cantrell used Exosite.

Over on the Exosite website, after signing up for a  free “Developer” account, it was a quick and easy mainly point-and-click exercise to configure my “Device,” “Data,”  “Events,” and “Alerts” (see Photo 3).  As a client, there’s no need to keep the “Thing’s”  Ethernet link powered all the time. Data only needs to  be sent when the garage door opens or closes, but I also  recommend sending a periodic heartbeat just in case. My  garage door monitor will only generate a minute or two  of network activity (i.e., door state changes and hourly  heartbeats) per day, so there’s opportunity for significant  energy savings compared to a 24/7 server.

It only takes a few minutes to set up a simple Exosite dashboard including an e-mail alert. I can “see“ my  garage door without getting off the couch and now, via Exosite, from the farthest reaches of the web.
