BASIC Compiler & Programming on Arduino Zero Boards (Crowdfunding)

BASIC Compiler Arduino

Arduino boards are normally programmed using Arduino “programming language” that’s more like an API using C/C++ language.  But when I started in high-school I remember learning Pascal and BASIC programming languages. Bruce Eisenhard also learned BASIC in the past, so he decided to port his company’s ARM BASIC compiler to Arduino Zero, and it should also work on other boards based on Microchip SAMD21G Arm Cortex-M0+ microcontroller. The compiler includes floating-point, strings, inline assembly, interrupts, pre-processor, and the BASIC firmware supports direct access to hardware registers so you can control digital and analog I/Os, ADCs, and other peripherals using BASIC programming language. A runtime monitor also facilitates debugging. The IDE used for development is called BASICtools that’s a free 30MB download which install programs and documentation. There are also libraries and examples from blinky to more complex code. It’s been possible to run interpreted BASIC on Arduino for a while, but Bruce notes compiled BASIC is at least 20 times …

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, …
