FOSSASIA 2019 Schedule – March 14-17

FOSSASIA 2019 Schedule

As its name implies, FOSSASIA is a Free and Open Source Software  event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event.  Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have the potential to grant bad actors access to your screen …

$16 ESP32-A1S ESP32 Audio Development Kit Comes with 2 Microphones, Audio Jacks & Headers

Espressif ESP32 WiSoC can be integrated into various applications, and earlier this year Espressif Systems released ESP32 LyraTD MSC Audio Mic HDK (Hardware Development Kit) which I could test with Baidu DuerOS using Mandarin. Since then the company released the ESP-ADF Audio Development Framework that beside Baidu DuerOS, now supports Google Assistant and Amazon Alexa, so you don’t need to speak or learn Chinese to use the kit! 🙂 Another ESP32 audio board was the similarly named ESP32-LyraT, and now we have at least more more option with Seeed Studio selling ESP32-A1S WiFi + Bluetooth ESP32 audio development kit for $16.90 on their store.

Rockchip RK3308 & RK3326 Datasheets Released

Rockchip unveiled their first Arm Cortex-A35 processors with RK3326 “Gemini” and RK3308 SoCs last March. Both are designed for Smart AI solutions, and the company showcased two development kits for smart speakers and smart displays based on the new processors. We’ve already known the basic details for the processors for some times, with for example RK3326 featuring a Mali-G31 Dvalin GPU, but I’ve now been informed more details have surfaced since Rockchip published documentations including datasheets. Rockchip RK3308 Key features and specifications: CPU – Quad-core Arm Cortex-A35 64-bit Armv8-A CPU with NEON,  ARMv8 Cryptography Extensions, 256KB unified system L2 cache, and VFPv4  FPU, System Memory – 256KB internal SRAM, support for DDR2, DDR3/DDR3L, LPDDR2 external memory up to 512MB Storage Internal BootROM OTP – Support 4K bit Size, 3.5K bit for secure application External I/F – 8-bits Asynchronism Nand Flash, eMMC 5.1, SPI Nor/Nand Flash, SD Card all bootable; System Components CRU (Clock & reset unit) PMU (Power management unit) …

Sony SPRESENSE Arduino Compatible GNSS + Audio IoT Board To Sell for $50 (in Japan)

Sony-Spresense-Arduino-Board

Last year,  we covered Sony Spritzer, an Arduino compatible with a Sony hexa-core Arm Cortex-M4F micro-controller, a built-in GNSS receiver, and an audio codec. The product page for this product is now gone, but it appears Sony only renamed it to SPRESENSE, made some design modifications, and is ready to launch the main board for 5,500 JPY (~$50), and the extension board for an extra 3,500 JPY ($32) on July 31, 2018. Sony SPRESENSE main board (CXD5602PWBMAIN1) specifications: MCU – Sony CXD5602 ARM Cortex-M4F ×6 micro-controller clocked at up to 156 MHz with 1.5MB SRAM Storage – 8MB Flash Memory GNSS – GPS & GLONASS Audio – 3.5mm audio jack Expansion I/Os Digital I/O Pins – GPIO, SPI, I2C, UART, PWM, I2S Analog Pins – 2ch (0.7V range) Camera interface USB – 1x micro USB port for programming and power Power Supply – 5V via micro USB port Dimensions – 50 x 20.6 mm Sony SPRESENSE expansion board (CXD5602PWBEXT1) specifications: …

A Closer Look at Mediatek MT8516 Cortex A35 SoM / Devkit for Android Things

Mediatek-MT8516-SoM

Earlier this month, Google released Android Things 1.0, the first stable release for the IoT operating system, and announced several certified SoMs (systems-on-module) based on NXP i.MX 8M, Qualcomm SDA212 & SDA624, and MediaTek MT8516 SoCs. However at the time, beside some information about the processor itself, there was not many details about MT8516 system-on-module. Since then, MediaTek wrote a blog post about their Cortex A35 solution for Android Things & Google Assistant, so let’s have a look. First the MT8516 SoM is not exactly what I had expected, but instead a complete single board computer, and this is why they call it virtual SoM (vSOM). Google defines the latter as reference design provided by the chip vendors and certified by Google. Mediatek MT8516 quad core Cortex A35 vSoM / development board specifications: SoC – MediaTek MT8516 quad core Cortex A35 processor without GPU System Memory – 4Gbit (512MB) DDR3L Storage – 4GB eMMC flash Connectivity – 802.11ac 2×2 MIMO …

Google Assistant Adds 6 New Voices, Supports Smart Displays, Will Expand to 80 Countries

Hey-Google

We’ve already seen announcements about Android P and Android Things 1.0 for Google I/O 2018, but the company also took the opportunity to provide an update to the new features coming to Google Assistant. Some of the improvements are specifically related to the audio features (voice assistant): Google Assistant is now naturally conversational so it can understand more complex requests such as asking the weather using expressions like “Will it be cats and dogs today?”. 6 new voices are now available, and John Legend’s voice is coming later this year. More voices should be supported in the future, thanks to improvements in AI and WaveNet technology from DeepMind that eliminates the needs for recording hundreds of hours of audio in a recording studio, and enabled adding new voices in just a few weeks. Continued Conversation – as its name implies – will allow Assitant and you to have a “natural conversation” without having to say “OK Google” for each request. …

Android Things 1.0 Released with Support for NXP i.MX 8M, Qualcomm SDA212/SDA624 and Mediatek MT8516 SoMs

Innocomm-WB10AT

Brillo Project was renamed to Android Things with the release of a developer preview back in December 2014, and the operating system enabling developers and companies to build and maintain Internet of Things devices at scale. The OS has now graduated so-to-speak with the release of Android Things 1.0 with long-term support for production devices, and this was to be expected as several Android Things devices were announced earlier this year. The new release adds supports for new system-on-modules (SoMs) based on the NXP i.MX8M, Qualcomm SDA212, Qualcomm SDA624, and MediaTek MT8516 SoCs. These modules are certified for production use with guaranteed long-term support for 3 years, and development hardware and reference designs for these SoMs will be available in the coming months. The Raspberry Pi 3 Model B and NXP i.MX7D boards and system-on-modules are still supported, but support for NXP i.MX6UL devices will be deprecated. Check out the hardware page for a full list of supported platforms. Google …
