E Ink Gallery 3 color ePaper offers faster refresh rate, higher resolution

This is confusing. E Ink just announced the Kaleido 3 color e-paper at the beginning of the month, and now comes up with E Ink Gallery 3 color e-paper. Before we try to look into the differences, let’s see what E Ink says about the new Gallery 3 color ePaper technology. Designed for the eReader and eNote markets, E Ink Gallery 3 is based on the E Ink ACeP (Advanced Color ePaper) with a full-color gamut achieved through a four-particle ink system: cyan, magenta, yellow and white, which allows a full-color gamut at each pixel. The earlier E Ink Gallery has a black and white update time of two seconds, and color updates of ten seconds. The new Gallery 3 ePaper technology slashes those times to 350ms for black and white and as low as 500 ms in fast color mode. The standard and best color modes have refresh rates […]

ESP32-C2 WiFi & Bluetooth LE 5.0 chip to support Matter WiFi protocol

Espressif ESP32-C2 is a new WiFi 4 and Bluetooth LE 5.0 chip the Shanghai-headquartered company has been working on since last year. The company claims it has better RF performance due to a smaller package reducing stray parasitics, and it will support the Matter protocol whose first version should become ratified later this year. The first ESP32-C2 product wafers have been received by the Shanghai team in spite of the current lockdown and quarantine in Shanghai due to the COVID-19, and teams in other parts of Asia, Europe, and Singapore are working without interruption on software integration into ESP-IDF and ESP-RainMaker. ESP32-C2 preliminary specifications: RISC-V core 272KB of memory Connectivity WiFi 4 + BLE 5.0 Tx power 20 dBm (FCC limit) 18 dBm for 802.11N MC7 packets (72.2 Mbps) Receiver sensitivity – -97 to -100 dBm for 1 Mbps 802.11B packets. Receive current – 58 mA Package – 4 x […]

StarFive releases Perf tool for highest performance RISC-V IP Dubhe (Sponsored)

As a StarFive Technology in-house developed RISC-V 64-bit ultra-high-performance core, Dubhe showcases the best performance RISC-V CPU core IP yet. It utilizes the latest RISC-V instruction set which includes RV64GC, bit operation extension (B), vector extension (V) V1.0, and hypervisor extension H (Hypervisor), making it ideal for high-performance computing. To pair with the Dubhe performance core, StarFive is now releasing “StarFive Perf Performance Profiling Tool”. StarFive has made Perf compatible with the hardware performance monitor (HPM) and micro-architecture events at the hardware level. Perf provides a reliable performance verification platform that not only facilitates customers to further discuss the Dubhe technical specifications but also accelerates the implementation of high-performance applications with RISC-V processors. Perf is an open-source and Linux-based performance analyzing tool capable of providing performance monitoring of the hardware events, tracepoints, firmware events, and dynamic probes. With the Perf profiling tool, we can monitor the performance of the predefined […]

Intel releases SDK for Cortex-M7 PSE found in Elkhart Lake processors

Elkhart Lake processors integrate the Intel Programmable Services Engine (Intel PSE) offload engine for IoT workloads powered by an Arm Cortex-M7 microcontroller that handles real-time IO control using GPIO, I2C, and/or UART interfaces, and supports functions such as remote, out-of-band device management, network proxy, embedded controller, and sensor hub. Until now the firmware was only provided as a closed-source binary, and Coreboot developers published an open letter to open the source code for the PSE firmware last December, and it’s been successful with Intel releasing the Intel PSE SDK based on Zephyr OS. The SDK combines open-source components (code samples, services, etc…) released under a permissive Apache 2.0 license (“License A”), and closed-source libraries and tools released under an Intel license (“License B”) allowing the redistribution and use in binary form, without modification. You’ll find everything on Github including documentation explaining how to get started with the Zephyr SDK, the […]
