STMicro STM32 ARM Cortex M3 Boards List and Wiki

STMicro STM32 has popular Cortex-M micro-controller found in the $2 “Blue Pill” board, STMicro’s own Nucleo Board, as well as many other variants. Olavi Kamppari (OliviliK), working on hard real-time control with EmBitz IDE, has created a detailed Wiki for STMicro STM32 on Github with lots of information, including an interesting comparison table of various STM32 Cortex M3 boards (and one GD32 board). I’ve reproduced the table in his wiki below, made is sortable & filterable, and added links to Aliexpress store found in other parts of the wiki. You can find much more details about each board in the Wiki. Thanks to Zoobab for the tip.

STMicro Unveils Two Low Cost STM32F7 ARM Cortex M7 Development Boards

STMicroelectronics introduiced its STM32F7 ARM Cortex M7 micro-controller family in 2014, and they released a $49 STM32F746G discovery board later in 2015. The company has now launched two new low cost development boards with the $23 STM32 Nucleo-144 board based on STM32F767 MCU, and a $79 Discovery Kit powered by STM32F746 MCU with TFT-LCD and MIPI-DSI support. STM32 Nucleo-144 development board Key feature of NUCLEO-F767ZI board: MCU – STMicro STM32F767ZI ARM Cortex M7 microcontroller @ 216 MHz with FPU, DSP, MMU, 2MB flash, 512 KB SRAM, 16 KB instruction TCM RAM (for critical real-time routines), and 4 KB backup SRAM Connectivity – IEEE-802.3-2002 compliant Ethernet connector USB – 1x micro USB OTG or full speed device  Extension: ST Zio connector including support for Arduino UNO v3 connectivity, and additional signals (A6 to A8, D16 to D72) ST morpho extension pin header footprints for full access to all STM32 I/Os On-board […]

STMicro Releases Linux based STM32 MCU Development Tools

Until a few years ago, most development tools for micro-controllers were only available for Windows, but as Linux gained popularity among developers and engineers, community of developers designed development tools running in Linux, but only a few companies are providing tools that run on Linux operating systems. The good news is that STMicro has just announced the release of STM32CubeMX configurator and System Workbench for STM32, for both Linux and Windows, with Mac OS supporting coming on Q2 2016. Developped by Ac6 embedded systems company, System Workbench for STM32 relies on Eclipse IDE, supports the ST-LINK/V2 debugging tool under Linux through an adapted version of the OpenOCD project, and can be used with various STMicro STM32 boards including Nucleo boards, Discovery kits, and other Evaluation boards. You can give it a try by visiting OpenSTM32 Community, but for some reasons they ask you to register before accessing the installation instructions. […]

Mediatek Helio X20 Processor to Features 10 Cores in Three Clusters

ARM first announced big.LITTLE processing on 2011, and since then we’ve seem several mobile processors providing two CPU clusters with “big” cores such as Cortex A15 or A57 and “LITTLE” core such as Cortex A7 and A53 to optimize performance and power consumption. With its latest Helio X20 (MT6797), Mediatek brings TINY.medium.huge processing with the first mobile processor using three CPU clusters, although a 3-level architecture has also been used before in Dhanush wearables SoC. The three clusters are divided as follows: TINY – Four ARM Cortex A53 core @ up to 1.4 GHz for best power efficiency medium – Four ARM Cortex A53 cores @ up to 2.0 GHz for a good performance / power balance huge – Two ARM Cortex A72 cores @ up to 2.5 GHz for maximum performance All three clusters are linked together and the memory bus via Mediatek Coherence System Interconnect (MCSI). Mediatek claims their […]

STMicro STM32F7 Series is the First ARM Cortex-M7 MCU Family

Right after ARM’s Cortex-M7 announcement, STMicro has listed STM32F7 MCU family based on the latest ARM core on their website. The family is comprised of 20 different MCUs with various flash size, packages, and with or without a crypto/hash coprocessor. The company expects their STM32F756xx microcontrollers to be used for motor drive and application control, medical equipment, industrial applications such as PLC, inverters, and circuit breakers, printers & scanners, alarm systems, video intercom, HVAC, home audio appliances, mobile applications, Internet of Things application, and wearable devices such as smartwatches. STM32F7 MCUs share the following key features: Cortex-M7 core @ 200 Mhz (1000 CoreMark/428 DMIPS) with L1 cache (4KB I-cache, 4KB d-cache) 320KBytes of SRAM with scattered architecture: 240 Kbytes of universal data memory a 16 Kbytes partition for sharing data over the bus matrix 64 Kbytes of Tightly-Coupled Data Memory (DTCM) for time critical data handling (stack, heap…) 16 Kbytes […]

Mediatek Smartphone and Tablet SoC Product Line (Mess) Explained

This week-end, I have been tipped about a $91 Mediatek MT8317 based 7″ Phablet, but I really did not know what to think about it as Mediatek seems to have so many SoCs, and really felt lazy trying to dig information about this. Yet, in the back of my head, I had decided to eventually make a post trying to clarifying Mediatek SoCs. This morning, I felt relieved not to have to spend hours investigating, as AndroidPC.es found an analyst paper doing just that, at least for recent and upcoming Mediatek processors. Mediatek Smartphone SoCs Roadmap MT6589 is certainly the most common SoC for cheap quad core smartphones, and starting this month, it will be available in MT6589M and MT6589T versions, the former with a weak video processing unit (VPU) and ISP, and GPU frequency, and the latter with higher GPU and CPU frequencies. Contrary to the table below, MT6589 […]

Kimdecent T21 mini PC Unboxing and Review

Androidpc.es has written a review for the low cost ($49) Kimdecent T21 dual core mini PC in Spanish, and I’ll provide a summary of the review in English below. Kimdecent T21 Unboxing Kimdecent T21 is an Android 4.1 HDMI TV Stick powered by Nufront NS115 dual core Cortex A9 processor. Check out my earlier post about Kimdecent T21 for specifications. The package comes with T21 mini PC, a power adapter with USB to micro USB cable, and a user manual in English. You can also watch  T21 Unboxing Video on YouTube. Kimdecent T21 User Interface & System Overview The user interface is a standard Android screen, albeit with power and volume buttons in the Status Bar. I don’t really find this interface very suitable for the TV, but you can always install your own launcher such as Android TV Launcher (apk), or other launcher apps available on Google Play. Beside […]
