In this project article, Andrei discusses SmartAgro, a device that combines field autonomy with ease of use, allowing farmers to give their plants a “voice.” It lets you visualize the temperature, soil humidity, UV radiation and more wherever you are, in real time and take action when it is most needed—whether that means turning on an irrigation system or preparing for cultivation.

 
RESOURCES FOR ENGINEERS

Product Focus: Rugged SBCs
By Jeff Child
Single board computers are used in such a broad sweep of applications—some that must operate in harsh environmental conditions. Rugged SBCs offer a variety of attributes to serve such needs, including extended temperature range, high shock and vibration resilience and even high humidity protection. This Product Focus section updates readers on this technology trend and provides a product album of representative rugged SBCs.

An Intro to Antenna Arrays
By Robert Lacoste
As an expert in RF technology, Robert has deep knowledge about antennas. And in this era of IoT, his expertise more relevant than ever. That’s because every wireless device has some kind of antenna and these antennas are often the root cause of engineering headaches. With that in mind, in this article Robert discusses the math, technology and design issues that are basic to antenna arrays.

Using Digital Potentiometers
By Stuart Ball
A digital potentiometer probably can’t be considered the most glamorous of electronic components. But it is easy to use and versatile. In this article, Stuart digs into the uses, advantages and disadvantages of the digital potentiometer, including how they contrast to mechanical potentiometers.

Semiconductor Fundamentals (Part 2)
By George Novacek
In Part 1 George examined the basic structures that make semiconductors work. But a lot more needs to be said about diodes, which are a key element of semiconductors. In Part 2, George dives deeper, this time looking at the current flow, depletion layer and electron physics that are involved in diode operations. He covers various types of diodes and the details of their operations.

A Hardware Random Number Generator
By Devlin Gualtieri
Men first walked on the Moon fifty years ago. On the same week as that historic event, Dev divided his time between watching the event on television and building a unique desktop novelty circuit, a random digit generator. This circuit used a Nixie tube for display and a handful of TTL integrated circuits to implement a linear feedback shift register. In this article, Dev updates his original design using the CMOS digital circuits available today and a 7-segment LED display. He also presents an improved version that uses a Microchip PIC MCU.


MICRCONTROLLERS DO IT ALL

Application-Specific MCUs
By Jeff Child
In contrast to microprocessors, microcontrollers tend to be used for specific applications. But even among MCUs, there’s distinct difference between general purpose MCUs and MCUs that are designed for very specific application segments, or even sub-segments. Circuit Cellar Chief Editor Jeff Child examines this class of MCUs that target everything from factory automation to appliance control.

The Laser Harp
By Alex Hatzis
Normally, you’d think that taking the strings out of a harp would be a downgrade. But in this article, Cornell student Alex Hatzis presents a system that does just that—replacing the harp strings with red lasers. Phototransistors are used to detect when the beams are intercepted by a person’s hand playing the harp, and some convincing real-time sound synthesis helps to create a new, high tech instrument.

The VAR-SOM-6UL offers a choice of three Cortex-A7-based i.MX6 UltraLite variants at up to 900MHz: the original i.MX6 UL and almost identical i.MX6 ULL and the newer, stripped down i.MX6 ULZ. The i.MX6 ULZ is also available on Variscite’s smaller DART-6UL module along with the UL and ULL.

The headless, up to 900MHz Cortex-A7 ULZ SoC offers most of the I/O of the of the i.MX6 UL and ULL, including their extensive audio interfaces. However, it lacks features such as the 2D Pixel acceleration engine and dual Ethernet controllers.

Recently, NXP launched a next-gen follow-on to the UltraLite line with its 28nm, FD-SOI fabbed i.MX7 ULP. The SoC adds a 3D GPU and Cortex-M4 to the power-sipping, single-core -A7.

The 3.3V powered, 67.6 × 33mm VAR-SOM-6UL offers BSPs for Yocto Thud and Debian Stretch, both with Linux Kernel 4.14.78. Boot2QT is said to be coming soon. The module ships with 128MB to either 512MB or 1GB DDR3L RAM, depending on differing citations. You also get 128MB to 512MB SLC NAND and 4GB to 64GB eMMC storage.

The VAR-SOM-6UL provides certified dual-band WiFi 802.11ac and Bluetooth 4.2 BLE, as well as dual 10/100 Ethernet controllers. (It’s unclear if these are included on the ULZ model.) Supported I/O includes USB 2.0 host and OTG ports, 8x UARTs at up to 5Mbps, and SD/MMC, 4x I2C, 4x SPI, and 2x CAN. There are also dual, 10-channel 12-bit ADC interfaces and support for a carrier-deployed RTC.

Industry Players Form Consortium Focused on UWB Interoperability

The ASSA ABLOY Group (which includes HID Global), NXP Semiconductors, Samsung Electronics and Bosch have announced the launch of the FiRa Consortium. The new coalition is designed to grow the Ultra-Wideband (UWB) ecosystem so new use cases for fine ranging capabilities can thrive, ultimately setting a new standard in seamless user experiences. Sony Imaging Products & Solutions Inc., LitePoint and the Telecommunications Technology Association (TTA) are the first companies to join the newly-formed organization.

The FiRa name, which stands for “Fine Ranging,” highlights UWB technology’s unique ability to deliver unprecedented accuracy when measuring the distance or determining the relative position of a target.  Especially in challenging environments, UWB technology outperforms other technologies in terms of accuracy, power consumption, robustness in RF connection and security, by a wide margin.

The starting point for UWB technology is the IEEE standard 802.15.4/4z, which defines the essential characteristics for low-data-rate wireless connectivity and enhanced ranging. It is the aim of the FiRa Consortium to build on what the IEEE has already established, by developing an interoperability standard based on the IEEE’s profiled features, defining mechanisms that are out of scope of the IEEE standard, and pursuing activities that support rapid development of specific use cases.

The capabilities of UWB promise to make it an essential technology in many areas including:

  • Seamless Access Control – UWB can identify an individual’s approach toward or away from a secured entrance, verify security credentials, and let the authorized individual pass through the entrance without physically presenting the credential.
  • Location-Based Services – UWB offers highly precise positioning, even in congested multipath signal environments, making it easier to navigate large venues such as airports and shopping malls or find a car in a multi-story parking garage. It also enables targeted digital marketing campaigns and foot traffic data. Retailers can present customized offers, government agencies can tailor their notifications, and entertainment venues can personalize recommendations during events.
  • Device-to-Device (Peer-to-Peer) Services – By providing precise relative distance and direction between two devices, UWB lets devices find the relative location of each other even without infrastructures such as anchors or access points. This allows people to easily find one another in crowded spaces or find items even when placed in hidden areas.

Due to its low power spectral density, UWB offers little to no interference with other wireless standards, so it is well suited for use with other wireless technologies, including Near Field Communication (NFC), Bluetooth, and Wi-Fi. There are also adjacent markets that leverage UWB in other ways, especially automotive.

Arm-based SBC has PoE, Wi-Fi/BT and More

By Eric Brown

Gateworks’ headless “Ventana GW5910” SBC runs OpenWrt or Ubuntu on a dual-core i.MX6 and provides GbE with PoE, WiFi/BT, optional GPS, Sub-1 GHz, and 2.4 GHz radios, and dual mini-PCIe slots for further wireless expansion.

Freescale’s i.MX6 was ahead of its time when it launched in 2011, and in the NXP era it it has continued to hold on in the embedded Linux market far longer and with greater dominance than any other processor. It’s only a matter of time before i.MX6-focused embedded vendors like Gateworks move on to the i.MX8 or other SoCs, but in the meantime there’s something to be said for working with a consistent SoC and platform/software platform rather than starting from scratch every few years.

Gateworks has just added to its i.MX6 collection by posting a product page for a new member of its Linux-supported, i.MX6-driven Ventana SBC family. Like other Ventana boards, the headless, wireless-oriented Ventana GW5910 supports -40 to 85°C temperatures.


 
Ventana GW5910 and block diagram
(click images to enlarge)


The Ventana GW5910 has the same 100 x 70mm form factor as the Ventana GW5220. Other Ventana boards include the 140 x 100mm Ventana GW5400, 100 x 35mm Ventana GW5530, and 70 x 35mm Ventana GW5510. The complete family of Ventana boards are compared here.

This is the first Ventana board to offer built-in WiFi/BT, via a Laird Sterling module with 802.11b/g/n and Bluetooth 4.2 LE. There’s also an optional Ti CC1352P module with dual-band sub-1GHz and 2.4GHz RF support, enabling 802.15.4g wireless protocols like 6LoWPAN, Thread, and Zigbee. There’s also an option for a u-blox ZOE-M8 GNSS Receiver.

Like the Ventana GW5530, the Ventana GW5910 offers mini-PCIe expansion, and this time there are two slots instead of one. One of them supports mSATA storage and the other is accompanied by a nano-SIM slot with LTE support.

The 802.15.4g and GPS modules do not use the mini-PCIe slots, so you could conceivably have five different wireless technologies onboard at once, as well as a GbE port with both passive and active 802.3af Power-over-Ethernet support.

Like most of the Ventana boards, the GW5910 uses the dual Cortex-A9 version of NXP’s i.MX6. The board defaults to an OpenWrt BSP with U-Boot, and there’s also an Ubuntu BSP available. It lacks the Yocto, Debian, and Android support found on the other boards.

The Ventana GW5910 ships with the usual 512MB DDR3 and 256MB flash, but you can bump those up to 2GB for volume customization orders. There’s also a microSD slot and connectors for 2x serial, SPI, and DIO. There are no USB or display ports, but you get JTAG, an accelerometer, an RTC with battery, an 8-60VDC input, and the Gateworks System Controller.

The Gateworks boards are extensively documented for both software and hardware. However, as noted in the CNXSoft post that alerted us to the GW5910, the software wiki has yet to post details specific to the SBC.

In this next part of his article series on Bluetooth mesh, Bob looks at how to create secure provisioning for a Bluetooth Mesh network without requiring user intervention. He also takes a special look at an attack called Man-in-the-Middle which Bluetooth’s asymmetric key encryption is vulnerable to.

By Bob Japenga

Both of our cars are more than 15 years old. My only new car envy is with the lack of a modern audio system. With a rental car, I’m always envious of the Bluetooth support and the seamless way I can connect and reconnect my phone to the car’s system. Most of the new audio systems are well thought out and easy to use. For my birthday, I got a Bluetooth device that would connect my phone to my dumb audio system in both cars. I have been very happy with the devices although they have two quirks. One is that they don’t work when the car has been left outside and it’s below zero. After the car warms up, it will happily function. But it doesn’t like subzero temperatures.

The other quirk—pointed out by my grandchildren—is that when it powers up, it announces: “Waiting for Pairing.” And then when it is paired, it reports “Paired.” The quirk is that instead of saying “Waiting for Pairing” it sounds like it is saying “Waiting for Perry.” The first time my grandkids were in the car, they asked: “Who is Perry and why are we waiting for him?” Now I can only hear “Waiting for Perry” when I turn on the car.
Pairing is the way two standard Bluetooth devices establish the initial link for one-to-one networking (Figure 1). Bluetooth mesh needs a much more sophisticated and secure method of linking the many-to-many network. That method is called provisioning. I introduced Bluetooth mesh provisioning in my last article (Circuit Cellar 345, April 2019) [1]. So, if you haven’t read that article, as a minimum, it will be important to go back to understand the terms that were defined in that article and which I will be using in this article.

Figure 1
Pairing is the way two standard Bluetooth devices establish the initial link for one-to-one networking.

As I mentioned last time, the Bluetooth specification [2] states that only if an Out-of-Band (OOB) public key is used or if an OOB action is taken to pass the public key (using user supplied information), “provisioning is Insecure Provisioning.” This statement will basically jettison any project that does not use one of these two OOB methods when presented to a savvy IT group. It did for us. Imagine presenting to your CEO a new product line using Bluetooth mesh that doesn’t use one of these two methods. Most likely the savvy CEO will ask: “What is the projected return on our investment?” AND “Is it secure?” Would you want to say: “Well, we are using Insecure Provisioning but other than that it is secure?”

I’m not convinced that the specification is entirely accurate in this statement and would appeal to the Bluetooth SIG to reconsider their wording. I want to elaborate on this idea in this article and provide some means for making provisioning secure without using either of the two OOB methods to pass the public keys.

Man-in-the-Middle

As I mentioned last time, Bluetooth uses asymmetric key encryption during the first part of provisioning. Asymmetric key encryption has one basic security flaw. It is subject to what is called a Man-in-the-Middle (MitM) attack. Let me illustrate this attack.

Imagine that Bob and Barbara are happily married. I know, normally everyone uses Alice in these illustrations, but my wife’s name is Barbara. They want to communicate some secret birthday plans about their grandson Sean. So, they both send over clear text their public keys (B1 and B2) (Figure 2). Bob encrypts all of his messages with Barbara’s public key B2, and sends them to Barbara. Barbara decrypts all of Bob’s messages using her private key B2P. Barbara sends all of her messages to Bob using Bob’s public key B1 to encrypt the data. Bob decrypts Barbara’s messages with Bob’s private key B1P.

Figure 2
Shown here is an example exchange that would be insecure because it would be subject to a Man-in-the-Middle attack. However, during normal asymmetric key encryption, the attack can be prevented through authentication.

Imagine that grandson Sean is a curious computer whiz and wants to know what’s he is going to get for his birthday. He intercepts the public key exchange B1 and B2 between his grandparents. Instead of passing on their public keys, he sends them his public key S1. So, when Bob and Barbara send their messages encrypted with S1 to each other he intercepts them and decrypts them using his private key S1P since they are encrypting their messages with his public key S1. He finds out what he is getting for his birthday and then encrypts the messages using Bob and Barbara’s public keys and sends them back to them. Bob and Barbara are clueless to the fact that Sean now knows what he is getting for his birthday.

That example illustrates that, if during the provisioning process, the public keys are not exchanged OOB, the process would be insecure because they would be subject to a MitM attack. However, during normal asymmetric key encryption, the way this can be prevented is through authentication. If Bob can know that a key is authentically from Barbara, he would immediate recognize that the key that Sean sent was not from Barbara. During normal Internet asymmetric key encryption this authentication is done through Certificates of Authority created by a trusted signing authority.

The Bluetooth provisioning process includes authentication of the device as part of the process. Authentication can either be using an OOB technique or without OOB. So, I would contend that if you use some means of authenticating that does not transfer the credentials over the Bluetooth network, your provisioning process would be secure in spite of what the Bluetooth specification says (I am definitely treading on thin ice here!).

Ultra96-V2 SBC adds Certified Wi-Fi and Industrial Temp Support

By Eric Brown

Avnet has unveiled a minor upgrade to its open-spec, 96Boards CE form-factor Ultra96 SBC. The Ultra96-V2 retains the $249 price and core features of the Ultra96, including the Arm/FPGA hybrid Xilinx Zynq UltraScale+ MPSoC, but it also makes a few key additions.

The biggest touted improvement is a new Microchip wireless module with the same 802.11n Wi-Fi capability, but with Bluetooth improving to 5.0 BLE. The major advantage here is that the module is said to be pre-certified in 75 countries.

Avnet has also “updated all components on the Ultra96-V2 to allow industrial temperature grade options so that the board can operate in harsh industrial applications.” We saw no details, however, on the specifics of the standard and industrial options. The term “industrial temperature” usually refers to -40 to 85°C.

Other new features include an Infineon power management IC (PMIC) and dedicated headers for UART and JTAG. The product page suggests that the previous I2C header has been removed, with I2C now being available only on the 40-pin low-speed header, but the block diagram indicates otherwise. There also appear to be four new LEDs.

Like the original, the Ultra96-V2 runs PetaLinux on the Zynq UltraScale+ MPSoC with a 1.5GHz quad-core, Cortex-A53 CPU block, a Mali-400 MP2 GPU, and a ZU3EG A484 FPGA — one of the lower-end UltraScale+ FPGA options. The SoC also features 2x 600MHz Cortex-R5 MCUs with vector FPUs and memory protection units for improved real-time processing. Avnet recently released a MSC SM2S-ZUSP module billed as the world’s first Zynq UltraScale+ based SMARC module.

In this article, Devlin Gualtieri describes his Raspberry-Rx Prescription Reminder project, a network-accessible, the Wi-Fi connected, Raspberry Pi-based device that alerts a person when a particular medication should be administered. It also keeps a log of the actual times when medications were administered.

ENGINEERING TIPS, TRICKS AND TECHNIQUES

The Art of Current Probing
In his February column, Robert Lacoste talked about oscilloscope probes—or more specifically, voltage measurement probes. He explained how selecting the correct probe for a given measurement, and using it as it properly, is as important as having a good scope. In this article, Robert continues the discussion with another common measurement task: Accurately measuring current using an oscilloscope.

Software Engineering
There’s no doubt that achieving high software quality is human-driven endeavor. No amount of automated code development can substitute for best practices. A great tool for such efforts is the IEEE Computer Society’s Guide to the Software Engineering Body of Knowledge. In this article, George Novacek discusses some highlights of this resource, and why he has frequently consulted this document when preparing development plans.

HV Differential Probe
A high-voltage differential probe is a critical piece of test equipment for anyone who wants to safely examine high voltage signals on a standard oscilloscope. In his article, Andrew Levido describes his design of a high-voltage differential probe with features similar to commercial devices, but at a considerably lower cost. It uses just three op amps in a classic instrumentation amplifier configuration and provides a great exercise in precision analog design.
