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

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

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 […]

STMicro unveils STM32MP2 Arm Cortex-A35/M33 MPU family starting with STM32MP25

STMicro has introduced its second generation of its STM32 MPUs (microprocessors) with the STM32MP2 moving to a 64-bit Arm architecture with Edge AI acceleration, multimedia features, graphics processing, and digital connectivity targeting industrial and IoT edge applications. The new family follows the STM32MP1 Arm Cortex-A7/M4 series introduced in 2019, and the first member of the family is the STM32MP25 with up to two 1.5 GHz Cortex-A35 cores coupled with an Arm Cortex-M33 real-time core clocked at 400 MHz, a 3D GPU, and a 1.35 TOPS NPU for AI acceleration. STM32MP25 key features and specifications: CPU – Single or dual Arm Cortex-A35 cores running up to 1.5 GHz Real-time MCU – Arm Cortex-M33 core running up to 400 MHz GPU – Unnamed 3D GPU for “advanced HMI” with support for the Vulkan API VPU – H.264 hardware video decoder and encoder AI accelerator – 1.35 TOPS NPU (Neural processing unit) System […]

MicroPython 1.20 released with Raspberry Pi Pico W support, mip package manager, smaller footprint

Damien George has recently announced the release of MicroPython 1.20 with support for the Raspberry Pi Pico W board., a new lightweight package manager called mip, a smaller footprint thanks to the use of compressed type structs, and many other changes. mip package manager The new mip package manager uses a custom protocol optimized for embedded systems to query and install packages, and intends to replace upip for installing packages from micropython-lib or any URL. Mip can be run directly on a device, as long as it has network connectivity, or via mpremote from a host computer. Damien explains all pure-Python drivers have been moved from the micropython repository to the micropython-lib repository as part of the change in order to make it easier to install the packages needed for a given project. MicroPython is getting smaller The MicroPython binary size has been reduced by many kilobytes for all ports […]

HARDWARIO CHESTER – A configurable Zephyr OS LPWAN IoT gateway with LoRaWAN, LTE IoT, GNSS connectivity

HARDWARIO CHESTER platform is a configurable LPWAN IoT gateway whose main function is to connect as many devices and environments as possible to the Internet using connectivity such as LoRaWAN, LTE Cat M1, or NB-IoT, as well as GNSS for geolocation. Contrary to most IoT gateways, it does not run Linux on an application processor, and instead, the “brain” of the CHESTER IoT gateway is a Raytac Bluetooth 5.0 module based on a Nordic Semi nRF52840 Arm Cortex-M4 microcontroller running Zephyr real-time operating system, which connects to LTE IoT modem and a LoRaWAN module through UART, and expansion modules through I2C, 1-wire, and GPIO interfaces. HARDWARIO CHESTER specifications: Wireless modules/chips Raytac MDBT50Q-P1MV2 Bluetooth 5.0 module based on Nordic Semi nRF52840 Arm Cortex-M4F MCU with 1MB Flash memory, 256kB RAM Nordic Semi nRF9160-SICA-B1A-R7 LTE-M/NB-IoT system-in-package (SiP) with Arm Cortex-M33 MCU, 1024 KB flash, 256 KB SRAM Murata CMWX1ZZABZ-078 LoRa module as […]

EVerest is an open-source software stack for car charging stations

EVerest open source car charging station software

EVerest is a software project initiated by PIONIX GmbH, but now part of the Linux Foundation’s LFEnergy initiative, whose primary goal is to develop and maintain an open-source software stack for EV charging infrastructure. EVerest supports multiple standards and it will run on any device from AC home chargers to public DC charging stations. I noticed the EVerest project in an upcoming talk at the Embedded Open Source Summit 2023 entitled ” EVerest: Electric Vehicle Chargers With Open Hardware and Software” and whose abstract reads in part: You will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open-source software stack for EV charging infrastructure. Following a quick introduction to EV charging technology, with explanations of the standards, protocols, and complexities involved, the talk will go into a deep dive into how you can build your own AC charging station. Reference […]

Embedded Open Source Summit 2023 schedule – Zephyr OS, Security, IoT, Embedded Linux, and more

The Linux Foundation has just announced the full schedule for the Embedded Open Source Summit, which will take place on June 27-30, 2023 in Prague, Czech Republic, as well as virtually starting on June 26. Over 175 sessions, birds of a feather (BoF) tracks, and workshops related to embedded and open-source innovation will be presented at the event itself comprised of six micro conferences: Automotive Linux Summit Europe, Embedded IoT Summit, Embedded Linux Conference, LF Energy Embedded Summit, Safety-Critical Software Summit, and Zephyr Project Developer Summit. Even though I’m not going to attend personally, I’ve gone through the schedule to create my own little virtual schedule with some sessions relevant that should be interesting to me and hopefully to CNX Software readers. Monday, June 26 (Virtual sessions) The first day of the event will have a Yocto Dev training in the morning, and a bunch of virtual sessions that are […]
