embOS-Ultra-MPU, the RTOS where safety and security meet Cycle-Resolution Timing
embOS-Ultra is a high-precision real-time operating system (RTOS) that uses Cycle-Resolution Timing to offer greater time accuracy and time resolution than any other RTOS on the market. Scheduling of all time-related events (including timeouts, delays, and periodic timing) can be specified in milliseconds, microseconds, nanoseconds, or timer cycles.
The RTOS allows time resolution to be precisely matched to individual CPU cycles via flexible system ticks. This cycle-based scheduling replaces traditional periodic system ticks with single-shot hardware timers, overcoming the limitations of tick-based scheduling with fixed tick intervals. This reduces unnecessary activity and helps extend battery life in low-power applications such as IoT devices and wearables, making it an efficient, energy-saving solution for embedded projects.

ESP32 Bluetooth Chip Contains Undocumented Commands, Sparking Security Concerns
Security researchers have uncovered 29 hidden commands in the ESP32 Bluetooth firmwareâpotentially opening the door to device spoofing, memory access, and advanced Bluetooth attacks.
The ESP32 chip, manufactured by Espressif and used in over a billion devices worldwide, was found to contain undocumented debugging functions that could allow attackers to manipulate RAM/Flash memory, impersonate devices, and exploit Bluetooth traffic.
This discovery was made by Tarlogic Security researchers, who presented their findings at RootedCON in Madrid. They warned that these commands could enable long-term persistence on compromised IoT devices, making them a prime target for cyber threats....

SEGGER J-Link debug probes and Flasher programming tools support STâs Stellar P and G MCUs
SEGGERâs J-Link debug probes and Flasher in-circuit programmers now fully support STMicroelectronics's Stellar P and G family of microcontrollers, which are specifically designed for the automotive industry.
With multiple cores, Stellar devices enable developers to consolidate multiple electronic control units (ECUs) into one high-performance ECU using a single Stellar MCU. This approach simplifies system architecture while maintaining the ability to handle diverse automotive applications.
"By adding support for the Stellar P and G family to our J-Link and Flasher tools, our solutions help developers address the complexities of modern automotive systems,â says Dirk Akemann, Head of Technical Marketing at SEGGER. "Our robust and efficient tools tailored for high-performance microcontroller development and programming are a perfect fit for the demanding processing units used in the automotive industry."...
Deepseek R1 in a Raspberrypi 5
After the releasing of Deepseek r1 model the world of AI changed a bit for how well optimized it is for that reason many tech enthusiasts wanted to test it how it works on a small computer like raspberry pi. Additionally, it is really interesting to run a AI model like Deepseek r1 locally but due to the resource limitation it was always not that impressive to run on a pi but due to the optimization of deepseek r1 it runs quite well. here I tried it with 8b parameters because 14b one requires more that 10GB ram which is not present in my device I am using a Raspberry pi 8GB model
if you are also interested the you can follow these steps
1. Make sure that your pi's system is up to date

Baremetallics: Running YOLOv5 on a Microcontroller
From community member @daleonpz:
"Running YOLOv5 on a microcontroller is no small task, given the modelâs computational requirements (>20MB). In this post, Iâll share how I successfully ran a simplified YOLOv5 model on an ESP32 microcontroller and optimized it for performance and memory constraints, achieving a model size of just 23KB."
