Arm Techcon 2019 Schedule – Machine Learning, Security, Containers, and More

Arm TechCon will take place on October 8-10, 2019 at San Jose Convention Center to showcase new solutions from Arm and third-parties, and the company has now published the agenda/schedule for the event. There are many sessions and even if you’re not going to happen it’s always useful to checkout what will be discussed to learn more about what’s going on currently and what will be the focus in the near future for Arm development. Several sessions normally occur at the same time, so as usual I’ll make my own virtual schedule with the ones I find most relevant. Tuesday, October 8 09:00 – 09:50 – Open Source ML is rapidly advancing. How can you benefit? by Markus Levy, Director of AI and Machine Learning Technologies, NXP Over the last two years and still continuing, machine learning applications have benefited tremendously from the growing number of open source frameworks, tools, […]

Linux 5.2 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds announced the release of Linux 5.2 last Sunday: So I was somewhat pre-disposed towards making an rc8, simply because of my travels and being entirely off the internet for a few days last week, and with spotty internet for a few days before that [*]. But there really doesn’t seem to be any reason for another rc, since it’s been very quiet. Yes, I had a few pull requests since rc7, but they were all small, and I had many more that are for the upcoming merge window. Part of it may be due to the July 4th week, of course, but whatever – I’ll take the quiet week as a good sign. So despite a fairly late core revert, I don’t see any real reason for another week of rc, and so we have a v5.2 with the normal release timing. There’s no particular area that stands […]

PanGu Board an SBC Based on the STM32MP1 Processor

The PanGu Board is a single board computer (SBC) that is feature-rich and versatile, at an affordable price point. The board powered by STMicroelectronics STM32MP1 processor was released in February of 2019 and hadn’t really made much a splash in the pool of microprocessors available at the time. The processor is now the main feature of the PanGu Board, an SBC with a host of features and utilizing the Arm dual-core Cortex–A7 MPU and the Cortex-M4 coprocessor to allow for more enhanced multimedia ability and all the heavy real-time processing that users are calling for today. Hardware Features MPU Dual Cortex-A7, 650MHz Cortex-M4, 209Mhz 3D GPU Flash & Memory 16-bit DDR3L, up to 1GByte 8-bit eMMC Flash Quad-SPI NOR Flash Supports Micro SD Audio 3.5mm stereo headphone jack support microphone input Display Parallel RGB LCD interface, the resolution up to WXGA (1366×768) MIPI DSI interface Support for resistive and capacitive […]

STMicro adds Dual-core Cortex-M7/M4 Microcontrollers to STM32H7 Family

STM32H7 is the high-performance family of STMicroelectronics Arm Cortex-M7 microcontroller. So far all STM32H7 MCUs had a single core, but the company has now added dual-core devices (STM32H74x/75x) comprised of an Arm Cortex-M7 core clocked at up to 480 MHz and a Cortex-M4 core clocked at 240MHz. In some way, this part is the little brother of STM32MP1 Arm Cortex-A7 + Cortex-M4 processor, as the new dual-core MCU also targets current products upgrade with the Arm Cortex-M4 core running legacy code, and the more powerful Cortex-M7 aimed at new features such as more sophisticated graphical interfaces, or offloading intensive workloads such as neural networks, checksums, DSP filtering, or audio codecs. Highlights of the new STM32H7 dual-core microcontrollers: Cores Arm Cortex-M7 at 480 MHz Arm Cortex-M4 at 240 MHz 3224 CoreMark / 1327 DMIPS Up to 2MByte Flash and 1Mbyte SRAM on-chip Dual-Bank Flash for seamless firmware updates “New” features MIPI […]

Kittenbot Meowbit Retro Game Console Features BBC Micro:bit Edge Connector

At first glance, Kittenbot Meowbit gaming console looks like a kid’s toy, but it’s bit more than that as its STM32 MCU can be programmed with MakeCode arcade, Scratch3.0 based Kittenblock, or MicroPython, and features the same edge connector as found in BBC Micro:bit board, and as such is compatible with several Micro:bit accessories. Kittenbot Meowbit specifications: MCU – STMicro STM32F401RET6 Arm Cortex M4 micro-controller Storage 2MB SPI flash to store Unicode character table (default) SD card slot to store programs or extend wireless modules Display – 160 x 128 full-color TFT LCD Sensor – Light sensor, temperature sensor, MP6050 gyroscope USB – 1x micro USB port for power and programming Expansion – 40-pin BBC Micro:bit “goldfinger” connector Misc – Charging/work LED, 2x user LED, power switch, reset button, DFU mode button, 4x direction buttons, A/B buttons, buzzer, multiplayer connector (15) Power Supply – 5V via USB, or 3.7~4.2V via […]

Pyboard D-series Wireless Micropython Boards Launched for $56 and Up

We’ve already mentioned the latest Pyboard D-series board at the beginning of February after it was introduced at FOSDEM 2019. The board comes with a powerful STM32F7 Arm Cortex-M7 microcontroller, as well as a WiFi and Bluetooth wireless module. The news is that the board has now launched for £43.80 in.c VAT ($56) and up. A better price comparison with other boards is normally achieved by comparing the ex. VAT price of £36.50 or about $48. That may still feel a bit pricey to some, but there was enough interest to snatch all available “PYBD-SF2-W4F2” boards, and this specific board is out of stock at the time of writing. However, there are multiple variants of the board and PYBD-SF3-W4F2 is still in stock for £58.20 inc. VAT (~$76.5). We’ve now got the full Pyboard D-series “PYBD-SF2-W4F2” specifications: MCU – STMicro STM32F722IEK Arm Cortex M7 microcontroller at 216 MHz with 256KB […]
