Arduino GIGA R1 WiFi board gets touchscreen display shield

Arduino GIGA Display Shield

The Arduino GIGA Display Shield is a 3.97-inch RGB touchscreen display designed for the Arduino GIGA R1 WiFi board introduced a few months ago with an STM32H7 dual-core Cortex-M7/M4 microcontroller and a Murata 1DX module for WiFi 4 and Bluetooth 5.1 connectivity. Besides featuring an 800×480 touchscreen display, the new shield offers some other features such as an MP34DT06JTR digital microphone, a Bosch BMI270 six-axis IMU, a 20-pin Arducam camera connector, and an RGB LED. Arduino GIGA Display Shield (ASX00039) specifications: Display – 3.97-inch touchscreen display with 800×480 resolution (model: KD040WVFID026-01-C025A),  16.7 million colors, 5-point touch, connected over I2C Camera I/F – 20-pin ArduCam camera connectors Sensors Bosch SensorTech BMI270 6-axis IMU with 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer STMicro MP34DT06JTR MEMS microphone Misc -1x RGB LED (I2C) Supply Voltage – 3.3V Dimensions – 106 x 80 mm The new shield can be mounted to the GIGA R1 […]

LoRaWAN IoT Button ships with open-source firmware, bootloader, and Android app

LoRaWAN IoT button

LoRaWAN is often used for asset tracking or environmental monitoring, for example, to track cattle location, or monitor temperature and humidity in a field, but n-Fuse’s “LoRaWAN IoT Action Button” enables human interaction and comes with open-source firmware, bootloader, and soon the source code for the Android app. Most of the n-Fuse STx-LR family of LoRaWAN nodes integrates environmental sensors but the LoRaWAN IoT Action Button is different with support supports single, double, and long presses, as well as tactile feedback. n-Fuse STx-LR family comes in three variants with the following key features: MCU – STMicro STM32L071KZU6 Arm Cortex-M0+ microcontroller @ 32 MHz with 192KB flash, 20KB RAM sta-lr – Action button with tactile feedback. stx-lr – TI HDC2080 environmental sensor (Temperature, Humidity), BMA400 motion sensor (acceleration), magnetic field sensitive Reed switch, ambient light sensor, and proximity sensor. ste-lr – Bosch BME680 environmental sensor with temperature, humidity, air pressure, and […]

Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.5 release

Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]

TRACEPaw sensorized paw helps legged robots “feel the floor” with Arduino Nicla Vision

TRACEPaw

Our four-legged friends don’t walk on tarmac the same way as they do on ice or sand as they can see and feel the floor with their eyes and nerve endings and adapt accordingly. The TRACEPaw open-source project, which stands for “Terrain Recognition And Contact force Estimation through Sensorized Legged Robot Paw“, aims to bring the same capabilities to legged robots. Autonomous Robots Lab achieves this through the Arduino Nicla Vision board leveraging its camera and microphone to run machine learning models on the STM32H7 Cortex-M7 microcontroller in order to determine the type of terrain and estimate the force exercized on the leg. But the camera is apparently not used to look at the terrain, but instead, at the deformation of the silicone hemisphere – made of “Dragon Skin” – at the end of the leg to estimate 3D force vectors, while the microphone is used to recognize terrain types […]

Flipper Zero hardware & wireless hacking tool gets an app “store” with open-source app

Flipper Zero

Flipper Zero portable multi-tool for pentesters and hardware hackers has now gotten an app “store” with currently around 100 free and open-source apps available through the device’s Android or iOS app. I missed it at the time, but the Flipper Zero launched on Kickstarter in July 2020 and was massively popular with close to 5 million dollars raised from almost 38,000 backers. The tool looks like a toy but it allows hacking with GPIOs and short-range wireless protocols such as Bluetooth, RFID, NFC, and infrared. Flipper Zero specifications: Wireless MCU  – STMicro STM32WB55RG with Arm Cortex-M4 application core @ 64 MHz, Arm Cortex-M0+ network core @ 32 MHz, 1024 KB flash, 256KB SRAM Storage – MicroSD card slot up to 64GB Display – 1.4-inch monochrome LCD (black on orange background) with 128×64 resolution via ST7565R SPI display controller Connectivity Bluetooth 5 LE & 802.15.4 via STM32WB55 microcontroller Bluetooth LE – […]

VL53L7CX Time-of-Flight (ToF) sensor offers camera-like 90° field of view

VL53L7CX wide FoV ToF sensor

STMicroelectronics VL53L7CX is the latest FlightSense multi-zone Time-of-Flight (ToF) distance sensor from the company with the main highlight between its camera-like 90° diagonal field of view, derived from a 60° x 60° field of view… This is a significant improvement over the 61° diagonal field of view of the previous generation ToF sensors such as the VL53L8 or VL53L5CP,  and the wider field-of-view is said to bring “lifelike situational awareness” to applications like home automation, computers, house appliances, robots, and industrial equipment with full-privacy since ToF sensors do not capture photos or videos like traditional cameras. STMicro VL53L7CX key features and specifications: 940 nm invisible light vertical cavity surface emitting laser (VCSEL) and integrated analog driver 60° x 60° square field of view (FoV) (90° diagonal) using diffractive optical elements (DOE) on both transmitter and receiver enabling square FoV Receiving array of single photon avalanche diodes (SPADs) Multizone ranging output […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets

snagboot

Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]
