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. […]

GigaDevice GD32 is a Faster, Software and Pin-to-pin STM32 Compatible Cortex M3 MCU

Las month, Olimex discovered a Chinese company called GigaDevice has made an STM32 clone called GD32 and compatible with STM32F103, but with higher core frequency (108MHz). Olimex has now posted an update after receiving a letter from GigaDevice, and trying GD32F103RBT6 MCU on their own STM32F103 boards. The company explained that GD32 was their own implementation, and claimed rights on GD32 trademarks, while Olimex discovered than GD32 was working just fine on their board having passed “all functional tests without any modifications”, and with all the same development tools and software code running fine. GD32F103xx datasheet (PDF / English version) can be downloaded to find a few more details: The GD32F103xx device incorporates the ARM Cortex-M3 32-bit processor core operating at 108 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3 MB on-chip Flash memory and up to 96 KB SRAM memory. […]

Ambiq Micro Apollo Low Power MCUs Promise Cortex M4F Performance at Cortex M0+ Energy Efficiency

Ambiq Micro is a US company founded in 2010 that focuses on “extremely low power” semiconductors leveraging their patented Subthreshold Power Optimized Technology (SPOT) platform. Earlier this year, they announced their first low power Cortex-M4F MCU Apollo family with claims of 5 to 10 times lower power consumption compared to other micro-controllers with the same performance. According to an EETimes article, they’ve at least partially backed their claims with a live demonstration at ARM TechCon 2015. Before checking out the test results, let’s have a look at the main features of Apollo MCU family: 32-bit ARM Cortex-M4F processor @ up to 24 MHz, with FPU, and wake-up interrupt controller with 12 interrupts Up to 512KB flash, 64-KB low-leakage RAM “Rich set of timing peripherals” Peripherals I2C/SPI master; I2C/SPI; UART; 10-bit, 13-channel, 1MS/s ADC Temperature sensor with ±2°C accuracy Voltage Range – 1.8 to 3.8V Power Consumption: active mode: 30µA/MHz (executing […]

Intel Unveils Three New Micro-controllers for IoT: Quark D1000, Quark D2000, and Quark SE

Intel’s subsidiary, Wind River, has recently announced two operating systems for the Internet of things with Rocket RTOS and Pulsar Linux supported respectively by Quark MCUs, and Intel Atom processors, as well as some ARM SoCs. But it’s not the only “IoT” announcement made by Intel in the last week, as I found out via EETimes that the company also unveiled three new Quark SoCs, namely Quark D1000, and Quark D2000, and Quark SE. Intel Quark D1000 Contrary to previous Quark processor and the upcoming D2000 and SE processors, D1000 is not compatible with x86 instructions set, and features the following: 32-bit Harvard CISC CPU @ 33 MHz with single cycle barrel shifter, two cycle multiplier, multi-cycle divider, integrated 32-bit timer, programmable interrupt controller, and JTAG debugger. 128-bit wide 32 kB code flash and 8 kB ROM 32-bit wide 8 kB SRAM and 4 kB data flash Osciallators 20-33 MHz […]

ATT7039AU Micro-controller Features an Energy Meter Unit for Power Meters

About two years ago, I purchased Northwest T8 power meter, and it worked fine for about three months, but one day the top plastic broke as as unplugged it, rubber bands prolonged its life for a few more weeks, but eventually the display stopped working, and keep it in my drawer for long while, until today, when I decided to have a closer look at how it was done. The PCB is called CZ-7039-B2, and the top includes the display, 4 user buttons, as well as JTAG through holes (P2) and 2.54mm header (P1) with TDO, TMS, GND and 3.3V signals, as well as a pin called P1600, but I still haven’t found out what it might be for. I’ve also taken the board out completely, to find out everything is basically handled by a single 48-pin chip called ATT7039AU. After a Google search, I quickly found out the chip […]

ARM: “Microcontrollers Are Better Because There’s No GPL”

[Update: ARM has pulled down the video and issued a statement] ARM has uploaded a video today entitled “Microcontrollers for Makers” showing the benefits of using micro-controller boards instead of processor based development boards such as Raspberry Pi or ODROID-C1, and their four first points are right on target, but the last one, as mentioned by Olimex, is completely wrong, and already made several people upset. Let’s go through the first four points: Micro-controllers are more energy efficient, so if your project is requires years on a cell-coin battery, MCUs are the way to go. MCU are cheaper too, now you can even get an MCU board for $1. They are smaller. The chip shown on the golf ball is Kinetis KL03 If you need real-time I/O, processors can’t beat micro-controller, that why people decide to connect an Arduino board to their Raspberry Pi, or products like UDOO Neo are […]
