The Visible Lisp Computer Runs on Adafruit ItsyBitsy M0 Board

Specified in 1958, Lisp is one of the oldest programming languages, and it does not appear to be widely used anymore. But if you want to play around with the 61 years old language, you may want to do so in a neat way via the Visible Lisp Computer, a Lisp interpreter that displays the contents of the Lisp workspace on an OLED display. It is a modified version of Technoblogy’s uLisp interpreter for Arm boards designed to run on  Adafruit ItsyBitsy M0, or other boards based on Microchip ATSAMD21E MCU on a prototyping board, connected to a 64×48 OLED display over I2C. uLisp gives you a workspace of 3072 free Lisp objects (each of 8 bytes) on this hardware, which exactly matches the 3072 pixels (64×48) from the display.  Having said that the program would also work on larger SSD1306-based OLED displays. The display shows free Lisp objects in black, and when an object is in use the corresponding …

$10 Wio Lite W600 Arduino Zero Compatible WiFi Board Follows Adafruit Feather Form Factor

Seeed Studio has just released the latest Arduino compatible Wio Lite W600 a combination of the W600 WiFi module mounted on the board and an Atmel  SAM D21 Arm Cortex-M0+ microcontroller. The WiFi core is a W600 2.4 GHz module featuring the Arm Cortex-M3. The SAM D21 is the same chip used by the Arduino Zero, so the Wio Lite W600 is compatible with Arduino Zero. Basic Specs The I/O level is 3.3V, and there are 6 analog pins and 14 digital pins, as well as one UART, I2C, and ICSP port. The board is powered through a USB Type C port or a 3.5V–4.2V LiPo battery. The latest feature is the W600 module is CE/FCC certified and supports 802.11 b/g/n WiFi. The WiFi module also features 1MB on-chip flash to store and run freeRTOS operating system. Seeed Studio provides a full Arduino W600 library and demos for many wireless access point options on Github. The New Wio Lite Series …

Arduino Partners with Chirp to Enable Data-Over-Sound M2M Connectivity

Announced on August 12, 2019, Arduino has partnered with the London-based Chirp, a wireless data-over-sound software solution for machine-to-machine connectivity.  The system has the ability to work online or offline, as long as there is a loudspeaker and a microphone available. The software works with the Arduino Nano 33 BLE Sense board in send and receive mode, while most Arduino MKR boards and Arduino Nano 33 IoT will also be supported by the SDK, but only to send data. The software and board are fully compatible with SDKs from a wide variety of platforms. The Nano 33 BLE Sense is available for purchase from the Arduino website, for $29.50. The sensor-rich Arduino Nano 33 BLE Sense is application-ready right out of the box, and Chirp is ready to start sending encoded data from a device fitted with an audio speaker, to the board’s built-in microphone, where it is encoded and delivered. The sound is above the hearing range of human’s, …

LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

Mini SAM Lego Board

If you are a fan of the Lego movie. Perhaps you have always wanted to use Lego bricks to make something innovative and techy. Then the Mini SAM M4 board is here for you, as it is a LEGO minifigure-sized development board. Additionally, the design and layout of the board is based around the classic 1980’s ‘spaceman’, and is made by Ben Shockley. Although the board is very small, it has a lot of wonderful features. It comes with an analog reference decoupling/filtering capacitors. Also, it has an analog to digital ferrite bead, as well as a debounce circuitry for the reset and user buttons. Furthermore, the board’s software and firmware can be developed using CircuitPython or Arduino. The development board is either based on the Microchip SAMD51G 48-Pin 32-Bit ARM – Cortex M4F MCU (Mini SAM M4), or features the Microchip SAMD21G 48-Pin 32-Bit ARM Cortex -M0+ MCU running at 48Mhz. Features of the Mini Sam M4 Lego Board …

DIP-Sized uChip Arduino Zero Compatible Board Loves Your Breadboard (Crowdfunding)

uchip breadboard-friendly arduino board

Most so-called breadboard-friendly boards that can easily be inserted into a breadboard often leave only one or two rows to play with on each side. This may suitable in many cases, but some people really want to use as many rows as possible, and come up with a solution using 90 degrees headers with 0.3″ spacing between them, just like 0.3″ wide chips do, and allowing the use of 4 rows on each side of the board. It does the trick, but this is not a standard solution, requires some bending of the headers, and covers part of the board so it’s not really ideal. A better way would be for somebody to design a narrow board using headers with 0.3″ spacing, and that’s exactly what Itaca Innovation has done with their Arduino Zero compatible uChip board designed in a 16-pin DIP package. uChip specifications: MCU – Microchip SAMD21 Arm Cortex M0+ MCU clocked @ 48 MHz (Arduino Zero Compatible) …

Arduino IoT Cloud Public Beta Launched

Arduino IoT Cloud Thing Widget

It’s long been possible to get data from sensors connected to official or compatible Arduino board, upload it to some cloud services, and watch the results is a neat web interface. But until now, you had to rely on third party services such as ThingSpeak, Adafruit.io, or Thinger.io to name a few. Arduino has now announced their own Arduino IoT Cloud services is entering public beta. You’d normally need to modify the sketch by hand to connect an Arduino board to the cloud, but Arduino IoT Cloud can automatically generate a sketch when setting up a new project, and help you get started quickly in less than five minutes. The Arduino IoT Cloud supports HTTP REST API, MQTT, Command-Line Tools, Javascript, and Websockets, and devices are secured using X.509 certificate-based authentication. To get started, you’ll need an Arduino MKR board, and create an account or login to Arduino IoT Cloud. Two boards can be selected from the interface: MKR1000 or …
