BBC Doctor Who “HiFive Inventor” Coding Kit aims to teach IoT to kids

In what should be one of the first RISC-V education platforms, the BBC, Tynker, and SiFive have just announced the BBC Doctor Who “HiFive Inventor” Coding Kit that comes with an MCU board with WiFi & Bluetooth and guided lessons for kids that teach them to code for the IoT. The HiFive Inventor board is based on a SiFive FE310 RISC-V microcontroller ( the same chip as found in the HiFive1 board) and an ESP32 Solo module for WiFi 4 and Bluetooth 4.x/5.x connectivity. Just like the BBC Micro:bit, HiFive Inventor provides a kids-friendly edge connector with I/O, an LED matrix, sensors, and more. The kit includes the HiFive Inventor hardware platform, a battery holder for three AA batteries (not included), the HiFive Speakers, an illuminated USB cable for power and programming, and alligator clips to connect the speaker or other add-ons to the HiFive Inventor board. HiFive Inventor board […]

XuanTie C906 based Allwinner RISC-V processor to power $12+ Linux SBC’s

Alibaba unveiled Xuantie-910 RISC-V core (aka XT910) in 2019 for powerful SoC with up to 16 cores, but an update in 2020 revealed the company planned to have a complete RISC-V core family for a wide range of application from low-power microcontrollers to server SoCs. At the time, I just assumed the company planned to keep their cores to themselves, but time proved me wrong as T-Head, the Alibaba subsidiary in charge of developing RISC-V cores, started to cooperate with Allwinner to develop open-source processors, which should lead to low-cost Linux capable RISC-V SBC very soon according to a tweet from Sipeed. Good News: We get first chip which based on XuanTie C906 (RV64GCV), it have abundant interface (HDMI/RGB/DVP/MIPI/GMAC/…), and will be able to run Debian system.Last and most important, the basic dev board price is start at 12.5$ (1% of HiFive Unleashed)。 pic.twitter.com/EJbXTJ5eMb — Sipeed (@SipeedIO) November 6, 2020 […]

Telink TLSR9 Wireless Audio & IoT RISC-V SoC integrates RISC-V DSP/SIMD P-extension

At the end of last month, there was a lot of buzz about Bouffalo BL602, one of the first RISC-V SoC with built-in wireless connectivity, namely WiFi 4 and Bluetooth 5.0 LE. We should expect more and more of those types of solutions, and Telink & Andes jointly introduced TLSR9-series of wireless audio chips for hearables, wearables, and other high-performance IoT applications. The chips are powered by an Andes D25F RISC-V 5-stage core that happens to be the first core to integrate RISC-V DSP/SIMD P-extension and offer Bluetooth 5.2, Zigbee 3.0, HomeKit, 6LoWPAN, Thread, and/or 2.4 GHz proprietary protocol. The press release focuses on the Andes core, but an article in Chinese allows use to find more about Telink TLSR9 family’s key features: CPU – Andes D25F 32-bit RISC-V 5-stage core @ up to 96 MHz (2.59 DMIPS/MHz and 3.54 CoreMark/MHz) with RISC-V DSP/SIMD P-extension Optional NNU – AI engine […]

BL602 IoT SDK and $5 DT-BL10 WiFi & BLE RISC-V development board

Yesterday, we wrote about Bouffalo BL602 32-bit RISC-V WiFI and Bluetooth LE wireless SoC that should eventually compete with ESP8266 in terms of price but with more features, higher performance. and more resources like memory and storage. At the time, I noted I could not find any tools for the processor, but I was informed a BL602 SDK (Doiting_BL) and documentation had already been released on Github. The basic readme and a user manual are already available in English, but the main documentation is still in Chinese with various examples to configure GPIO, YART, WiFi, and Bluetooth. You’ll find the documentation in Github, as I could not find a website yet:

git clone https://github.com/SmartArduino/Doiting_BL

1	git clone https://github.com/SmartArduino/Doiting_BL

Go to Doiting_BL/docs/html folder and then open index.html in your browser to access the documentation. The SDK works both in Windows and Linux and relies on either Eclipse & OpenOCD or Freedom Studio & OpenOCD. A graphical software […]
