LUNA: Lets Your Capture And Analyze Traffic Between Hosts and USB devices

Posted on by Abhishek Jadhav

LUNA board

Lately, we have seen several interesting projects up for crowdfunding that you can support and get rewards for as well. One such project coming soon is the LUNA hacking device that is nothing but a PCB with some integrated circuits and complex circuitry. With this new device, you can build, test, monitor, and experiment with any USB device you can think of.

Can you imagine one hardware exhibiting three extremely useful capabilities for all kinds of developers? This will keep many of the designers clamoring over the ability to act as a high-speed USB protocol analyzer, a USB-hacking multi-tool, or a USB development platform. Looking at the specifications, you will notice that the hardware comes with Lattice Semiconductor LFE5U-12F ECP5 FPGA that is supported by the yosys+nextpnr open-source FPGA flow.

LUNA USB Protocol Analyzer

“Out-of-the-box, LUNA acts as a USB protocol analyzer capable of capturing and analyzing traffic between a host and any Low-, Full-, or High-Speed (“USB 2.0”) USB device. It works seamlessly with our open-source ViewSB software, which translates captured USB traffic into a human-readable format. ViewSB runs on Linux, macOS, Windows, and FreeBSD.”

For anyone who has been wishing to monitor and analyze the traffic of any USB 2.0 device. Along with the protocol analysis, the manufacturer doesn’t stop surprising us with its immense capabilities that allow you to create your high-speed USB device. This can be done using the FaceDancer library with which you don’t only get to create USB devices but also emulate them in high-level Python programming.

This is not the first time we have seen the LUNA team working in the USB space. Earlier, we have come across several educational materials that deal with hacking and working on USB devices. With onboard integrated circuits, you can easily configure the FPGA and run diagnostic tests like the built-in USB-to-serial communications bridge for FPGA debug I/O.

As mentioned earlier, the project is expected to hit crowdfunding soon. For more information on the product, head to the official program page where you can find information related to the hardware and create your own USB design.

Arduino IDE Offers Support for the Raspberry Pi Pico

Posted on by Tope Oluyemi

Arduino recently announced their Arduino Nano RP2040 Connect board, which is a port of the latest Raspberry Pi Pico. Along with it, they’ve also decided to port the Arduino core, bringing the Arduino IDE, libraries, and more to the Raspberry Pi Pico. Even though the official port is yet to be available, Earle F. Philhower has taken it upon himself to build his own port of the Arduino Core for all RP2040 boards! He made its contents available on his GitHub repository.

Earle is still developing the port because he intends to include more features such as an installable filesystem, I2S support, and an improved debug infrastructure. However, he has installed most of the common features like digitalWriteRead, analogWriteRead, hardware UART, SPI, and Servo control which are already up and running. This is great news. While we wait for the Arduino team to provide their official support and boards, you can use many of the existing Arduino libraries and code with the Raspberry Pi Pico. Also, the code Earle Philhower uses also integrates a ready-to-use toolchain. The integrated toolchain supports the major operating systems. You can visit the GitHub repository readme for the full list of working features and caveats.

Earle provided a step-by-step procedure that you will need to follow for your first Arduino sketch upload. You will need to hold the BOOTSEL button down while plugging in the Pico to your computer, then you can press the upload button in the Arduino IDE to transfer the sketch to your Pi Pico. After transferring the sketch, you will have to select the appropriate serial port shown in the Arduino Tools > Port > Serial Port menu once. This enables the auto-reset tool to identify the correct device to reset.

Earle also explains that the Pico will occasionally encounter a hard hang and be unable to respond to an auto-reset request. However, you can just follow the steps above to resolve the issue.

Earle also provides instructions on how to install it with Arduino IDE, by following the instructions below:

For a while now, Arduino and Raspberry Pi have been in sync towards providing beginner-friendly platforms for students and hobbyists to learn about electronics and computers. With the news of the Raspberry Pi Pico microcontroller, and Arduino’s promise to support it, we are seeing history being made with the merging of two electronics and computing education platforms that have been kept distinct for the past few years.

This is great news for beginners who are venturing into digital making. With the Raspberry Pi Pico, you can leverage the tools and resources provided by both the Raspberry Pi Foundation and Arduino for learning and building. For now, Raspberry Pi Pico officially can be programmed in two languages, C/C++ and MicroPython. Programming in MicroPython is easier, with integrated support for the beginner-friendly Thonny Python IDE.

Minima; The Tiny, SMD-Based, Arduino Compatible Development Board

Posted on by Emmanuel Odunlade

Miniaturization is a constant goal for any electronics hobbyist or embedded systems designer. The smaller the device, the higher the number of potential applications. Several designers and hobbyist have had a go at miniaturizing several members of the Arduino family of boards since they became popular, but in more ways than one, it is probably safe to say none has been able to achieve the level of miniaturization that Hamish Morley recently demonstrated with his new board; Minima.

A small and versatile Arduino compatible microcontroller module, Minima, was designed to help electronics hobbyist and designers quickly go from breadboard prototypes to usable products, thanks to its SMD/SMT-based form factor, which makes it easy to embed it in devices without altering the product’s size or shape, significantly.

Minima was designed with features that make it a great board for everyone, from the hobbyist who just wants to tinker to the design engineer looking to build a “serious product”. It is based on the same 32-bit Microchip SAMD21G18A processor used in popular Arduino boards (and compatible work-likes) like the Arduino Zero, the MKR Zero, and Adafruit Feather series.

Despite its small form factor, Minima packs enough functionality and features to earn itself a seat at the table of cool and useful boards. A summarized list of its features and specifications is provided below:

Features and Specifications:

  • Very small size (19.8mm x 16.6mm)
  • Easy to solder (no need for intricate soldering or reflowing)
  • SMD ready and rapid prototyping friendly (no need to bother about the time you’d use to solder tiny components, just base your design around the Minima footprint and accelerate your prototyping and designing)
  • CPU: 32-bit Microchip SAMD21G18A processor with a clock speed of 48MHz
  • 256KB of flash storage
  • 32KB of RAM
  • Very low power consumption
  • 3.3V, 150mA Voltage Regulator (supports up to 16v input voltage. )
  • ESD suppressor for native USB (helps to improve reliability for mission-critical applications)
  • 2x LEDs: 1x Green RX/TX LED for the Native USB, and 1x Red user programmable LED
  • Offers reverse voltage protection
  • 18x GPIO (5x pins are analog-capable)
  • SPI, I²C, and UART interfaces
  • PWM and hardware interrupts
  • 1x Reset button

According to Morley, Minima was designed for use across all sorts of embedded applications, and considering its size and features, one cannot but agree as I see it fitting into diverse kinds of use cases from IoT and tracking solutions to all sorts of wearables.

Morley recently launched a Kickstarter campaign which has now raised $4000, 4 times its initial goal of $1000. The slots in the campaign are filling up fast and at the time of this writing, there are still a few pledge options. So if you are interested, you better hurry.

If you, however, miss out on the campaign for any reason, Morley has assured you that the design will be available on Github soon, with all the software and hardware files you will need to make your own version of the board!

More information on Minima, its specs, cost, and availability can be found on the product’s Kickstarter page.
