CML Microcircuits Ltd announced the introduction of the CMX7146, a flexible data modulator that simplifies the design of transmit-only solutions using BPSK (binary phase-shift keying) and differential BPSK modulation (also referred to as PRK, phase reversal keying, or 2PSK). The CMX7146 generates precise baseband analog in-phase and quadrature signals with programmable signal filtering. This generates […]

Hardware-based trust anchors are key for connected applications and smart services, whether for a robotic arm in the smart factory or automated air conditioning in a private home. The new OPTIGA Trust M solution from Infineon Technologies AG helps manufacturers to enhance the security of their devices while at the same time improving overall system […]
Software adds support for 3rd party debug probes via GDB protocol
SEGGER Embedded Studio V4.20 adds fully configurable support for debug probes using the GDB protocol. The new version can now be used with any debug probe that comes with a GDB Server. This new feature is included in all editions: ARM, Cortex-M, and RISC-V, on Windows, macOS, and Linux 32- and 64-bit platforms. Embedded Studio […]
The working principle, applications and limitations of ultrasonic sensors
The ultrasonic sensor (or transducer) works on the same principles as a radar system. An ultrasonic sensor can convert electrical energy into acoustic waves and vice versa. The acoustic wave signal is an ultrasonic wave traveling at a frequency above 18kHz. The famous HC SR04 ultrasonic sensor generates ultrasonic waves at 40kHz frequency. Typically, a […]
The demands of boot drives in the Embedded Enterprise aren’t what you’d expect
by Steffen Allert, Hyperstone Storage modules are an integral part of consumer, industrial, and enterprise systems. The unique work-load and challenges of these markets dictate the design and components making up the systems. It is commonly understood that the storage systems designed for the enterprise sector are heavily focused on achieving significant endurance rates. The […]
Autonomous vehicle sees with LiDAR eyes
Automakers are struggling to deliver the first commercially available fully autonomous car (SAE Level 5). There are a lot of vision technologies and sensors available, but fine-tuning them has proved to be challenging. Cars need to “see” objects, moving or stationary, from far away enough to react and make driving decisions. One of the most […]
AI kits for hobbyists powered by NVDIA CPUs
SparkFun Electronics is pleased to announce the release of the JetBot AI Kit powered by the NVIDIA Jetson Nano and the Course Materials Kit for “Getting Started with AI on the Jetson Nano” from NVIDIA’s Deep Learning Institute. SparkFun’s version of the JetBot merges the industry-leading machine learning capabilities of the NVIDIA Jetson Nano with the vast […]
A better way to measure lidar
The special demands of sensors needed for autonomous driving have brought suggestions for different measurement metrics. Leland Teschler, Executive Editor A few months ago, sensor maker AEye made a media splash when it claimed it had developed a super-speedy lidar sensor that could hit a scan rate of 100 Hz or more. That speed outpaces […]
