Status of Zephyr and NuttX RTOS support for ESP32

Espressif has recently announced that both Zephyr and NuttX open-source real-time operating systems had gotten official support for the ESP32 series of WiSoCs. It’s been a long time in the making, and when I first tried the community developer port of Zephyr OS on ESP32 in 2018 it did not work well at all, and I could not even make the blink LED sample work on Wemos Lolin32 board, and the WiFi sample would not even build. But time has passed, Espressif Systems started to officially work on Zephyr in 2020, and now I/Os, WiFi, and some other features work on Zephyr and NuttX RTOSes. Zephyr on ESP32 We first wrote about the Zephyr Project in 2016 describing the OS as follows: Zephyr Project is a lightweight real-time operating system (RTOS) designed for IoT applications and comprised of a microkernel for lower priority tasks, as well as a nanokernel to […]

Picovoice Cobra Voice Activity Detection Engine shown to outperform Google WebRTC VAD

Picovoice Cobra Voice Activity Detection (VAD) engine has just been publicly released with support for Raspberry Pi, BeagleBone, NVIDIA Jetson Nano, Linux 64-bit, macOS 64-bit, Windows 64-bit, Android, iOS, and web browsers that support WebAssembly. Support for other Cortex-M and Cortex-A based SoCs can also be made available but only to enterprise customers. Picovoice already offered custom wake word detection with an easy and quick web-based training and offline voice recognition for Raspberry Pi, and even later ported their voice engine to Arduino. Cobra VAD is a new release, and, like other VADs, aims to detect the presence of a human voice within an audio stream. Picovoice Cobra can be found on Github, but note this is not an open-source solution, and instead, libpv_cobra.so dynamic library is provided for various targets, together with header files and demos in C, Python, Rust, and WebAssembly, as well as demo apps for iOS […]

USB board emulates CR2032 or CR2016 coin cell battery

You can now develop CR2032 or CR2016 powered devices without having to use an actual coin cell thanks to Peter Misenko’s (Bobricius) “coin cell battery emulator CR2016/CR2032”. The USB board contains a rounded part that is compatible with CR2016 or CR2032 coin cell batteries and allows you to power your target board via USB. The board also includes holes for alligator clips to measure the current, and by extension the power consumption. Coincell battery emulator CR2016/CR2032 specifications: Power Supply 5V via Micro USB port 3V regulator 3V + GND pins for incompatible holders Power measurement – 2x alligator clip holes for Amperemeter mode (the onboard solder jumper must be open) Dimensions – Designed for a CR2016 battery (1.6 mm thick), but an adapter can be soldered for a CR2032 battery (3.2mm thick) It’s not a size fit all solution since it will only work with a specific type of battery […]

Beelink SER3 Review – A good AMD Ryzen 7 mini PC… after tweaks

Beelink has just launched a new mini PC called the SER3. It is another ‘new’ mini PC using an older CPU, in this case, an AMD mobile processor. However, the performance is surprisingly good once a few tweaks are made to the stock configuration. Beelink kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu together with using an eGPU. Hardware Overview The SER3 physically consists of a 126 x 113 x 40mm (4.96 x 4.45 x 1.57 inches) square metal case. As an actively cooled mini PC, it uses AMD’s older 12 nm Zen+ Ryzen 7 3750H Picasso processor which is a quad-core 8-thread 2.3 GHz mobile processor boosting to 4.0 GHz with Radeon RX Vega 10 Graphics. The front panel has an illuminated power button, dual USB 3.0 ports, a Type-C USB 3.0 port with Alternate Mode, a 3.5mm headphone jack, and a […]
