STMicro unveils VL53L5 multi-zone ToF ranging sensor

We’ve previously covered or even tested STMicro Time-of-Flight (ToF) ranging sensors with devices like VL53L0X with up to 2-meter range or VL53L1X extending the range to a maximum of 4 meters to measure the distance to one object aka region of interest (ROI). Those are used in various applications including the autofocus function in smartphones for example. The company has now introduced a new model with VL53L5 ToF laser-ranging sensor boasting increased camera Field-of-View coverage and 64-zone spatial resolution to enable new features such as touch-to-focus, multiple-target identification, flash dimming, or video tracking assistance. VL53L5 highlights: 940 nm invisible Vertical Cavity Surface Emitting Laser (VCSEL) and integrated analog driver 61° diagonal square system field of view (FoV) using diffractive optical elements (DOE) on both transmitter and receiver Receiving array of single-photon avalanche diodes (SPADs) Parallel multi-zone output – Either 4×4 (16 zones @ 60 fps) or 8×8 (64 zones @ […]

InferX X1 SDK, PCIe and M.2 Boards for edge inference acceleration

Last week, Flex Logix announced the InferX X1 AI Inference Accelerator at Linley Fall Conference 2020. Today, they announced the InferX X1 SDK, PCIe board, and M.2 board. InferX X1 Edge Inference SDK The InferX Edge Inference SDK is simple and easy. The input to the compiler can be an open-source high-level, hardware-agnostic implementation of the neural network model that can be TensorFlow Lite or ONNX model. The compiler takes this model and looks for the available X1 resources and generates a binary executable file. This goes to the runtime which then takes the input stream, for example, a live feed from a camera. The user has to specify which compiler model, then the InferX X1 driver takes it and sends it to hardware. The binary file generated is fed to InferX X1 through the runtime. Then it takes the input data stream with a user-specified model and gives the […]

$54 Xiaomi Mijia Paipai wireless HDMI system connects your computer to your TV

A few years ago, we covered plenty of cheap Miracast adapters that plugged into your TV and used to mirror your Android or iOS smartphone display to a larger TV screen. It’s also possible to use Miracast on computers with WiFi, and since many TVs implement Miracast, extra hardware is often not needed. But in case your TV and computer are not compatible, Xiaomi Mijia Paipai wireless HDMI system [Update Nov 2020: actually called “Mi Wireless Casting Adapter” in English] solves this issue with a wireless HDMI receiver connected to your TV and a wireless HDMI transmitter connected to a USB port from your computer or laptop. Both the receiver and transmitter have similar dimensions (149.6 x 61 x 12.5 mm vs 152 x 60 x 11.9 mm) and weigh 38.5 grams in a form factor similar to Google Chromecast. The company says Windows 7 to 10 and Mac OS […]

The quest for a blob-free WiFi & Bluetooth stack for BL602 WiSoC

I thought I was done writing about Bouffalo Lab BL602 WiFI & Bluetooth RISC-V SoC for a while after first covering the chip itself, and then an inexpensive BL602 development board this weekend. But the BL602 SDK has shown up in various Github repositories, including Bouffalo Lab’s own bl_iot_sdk repository, and as more people are looking into it, there’s now an effort to develop a fully open-source blob-free WiFi & Bluetooth stack for BL602, and other Bouffalo Lab WiFi and/or Bluetooth wireless chips. Last day we communicate with Bouffalolab, finally they release the SDK of BL602 (RV32 chip of wifi+bt), all code is open, except libblecontroller.a, libatcmd.a, libbl602_wifi.a (while they have all symbol inside)https://t.co/giHsQ4ezXxwe have a fork too https://t.co/FiaAIxLBc8 — Sipeed (@SipeedIO) October 27, 2020 First, Sipeed says the code is mostly open-source except for three libraries: ibblecontroller.a, libatcmd.a, libbl602_wifi.a, all of which are un-obfuscated, and easy to disassemble. Then […]
