Keil RTX RTOS is Now Available for Energy Micro EFM32 MCUs

Energy Micro has recently announced the availability of the Keil RTX real-time operating system (RTOS) as part of its Simplicity Studio tool suite. The Keil RTX has been optimized for ARM Cortex-M processors to provide flexible scheduling and high-speed operation, and has been improved to enable an ultra-low power, deep-sleep mode between tasks. Energy Micro has implemented a tickless mode in Keil RTX. This mode allows the EFM32 Cortex M3 MCUs to wake up only when needed, either at a scheduled time or on an interrupt event. This results in much lower power consumption in sleep mode compared to other SysTick implementations. The video below shows the difference between SYSTICK mode where the system consumes about 2.7mA in active mode, and 830 uA in sleep mode to the new tickless mode where the MCU still consume the same amount of energy in Active mode, but only 1uA in sleep mode, […]

Mele A1000G Quad Set-Top Box Features AllWinner A31 SoC

Mele A1000 Android set-top box based on AllWinner A10 is one the best platform to play with Linux on ARM, thanks to its low cost, numerous features, hackability, and the work of the developers’ community on arm-netbook mailing list, and now in sunxi-linux. I like it so much it’s the first item in my short list of hackable gadgets. However, the hardware specifications of the original Mele A1000 may be too weak for some of today’s applications. So I’m pleased the announce that Mele A1000G Quad is now available (for pre-order) with AllWinner A31 quad core Cortex A7 SoC, 2GB RAM and 8GB Flash. Here are the specifications for Mele A1000 Quad STB: SoC – AllWinner A31 quad core Cortex A7 @ 1.5GHz + PowerVR SGX544MP2 GPU System Memory – 2GB DDR3 RAM Storage 8GB Flash SD card slot SATA connector (most probably via a USB to SATA chipset) Video […]

Open Source Time Machine #2 – Build A Complete Watch Yourself

There are already some watches such as Texas Instruments ez430-Crhonos and MetaWatch that are used as development platform and let you develop software yourself. Some hardware documentation is usually provided as well, but Energy Micro forums’ member hairykiwi is trying to go a bit further. He created a watch based on EFM32 Cortex M3 MCU and already released the KiCad schematics and gerber files, with 3D printer files and firmware source code to be released once they are ready. The project is called “Open source Time Machine #2” (OTM2). The project makes use of the following components and features: EFM32LG332F256 – Energy Micro Cortex M3 Leopard Gecko MCU with 256KB flash and 32KB SRAM A 128×128 pixel (23.2 x23.2mm visible area) ultra low power Memory LCD from Sharp Microelectronics, Recharge and programming via Micro USB connector. JTAG programming is also available. 150mAh Li-Po Battery + on-board battery fuel gauge IC. […]

Samsung Exynos 5 Octa Antutu Benchmark Results

The highly anticipated Samsung Galaxy S4 smartphone should become available later this month in three versions depending on the country where you reside: GT-I9500 – Exynos 5 Octa @ 1.6 GHz without LTE GT-I9505 – Snapdragon 600 @ 1.9 GHz with LTE SHV-E300S – Exynos 5 Octa @ 1.8 GHz with LTE GS4 will also be the first device to feature Exynos 5 Octa octo-core processor, so until people get their hands on the device, one way to know how fast it can perform is to get some benchmarks running on the devices. SamMobile received the latest Antutu benchmarks for GT-I9500, and as expected, the results are pretty impressive with a score of 28018. This score is about 19% higher than GT-I9505 (Snapdragon 600) which scores 23607 points. As usual, the detailed scores are not available which is pretty annoying, but I’d assume both the CPU, thanks to the 4 […]

Kontron Unveils SMARC Starterkit for ARM Systems-on-Module

You may have previously heard about ULP-COM (Ultra Low Power CoM), a standard for systems and computers on module. The standard has been ratified by the Standardization Group for Embedded Technologies (SGET) in February 2013, and renamed to SMARC (Smart Mobility ARChitecture). This standard is specifically designed for low power designed, and is currently only used with ARM SoC. Kontron was involved in the design of this standard, released several ULP-COM, now SMARC, compatible CoM based on TI, Freescale and Nvidia SoC, and yesterday the company just announced SMARC Starterkit will all hardware and software components needed to get started with evaluation and development. This starter kit comes in a carrying case with the following items: SMARC Evaluation Carrier Board 7″ Display PM070W4 (WVGA – 800×480) Touch USB Kit ETP04USBR Mounting Kit Adapter and Cables: 1x Kontron LVDS Jili30 Adapter incl. cable 1x DSUB9 1x micro USB USB A Storage […]
