MUSES-α & MUSES-β DVB-T/C, ISDB-T, DTMB & ATSC Modulator Boards Review – Part 1: The Hardware

V-Bridge Muses digital TV modulator boards launched on Kickstarter earlier this month, with the cheaper $200 MUSES-α board modulating video from a PC, and $600 MUSES-β turnkey solution capable of broadcasting HDMI or AV + stereo input to various digital TV standards including DVB-T/C, ATSC/QAM, DTMB, and ISDB-T/TB without the help of a computer. The company sent me the two hardware kits for evaluation and review on CNX Software, and today I’ll start by showing off the hardware I received. I got 3 packages and a F-female to F-female cable, which means you can connect the board directly to your TV tuner without having to rely on actual RF signals, and potential legal issues that goes with it. The first package I open if for the PC modulator kit that include MUSES-α board, an “RF” board, as a USB cable to connect to your computer. MUSES-α board features Vatek A1 […]

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. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com

Micrium µC/OS RTOS Is Now Free for Makers and Startups

According to UBM embedded market study for 2015, Micrium µC/OS real-time operating system only came second after FreeRTOS when the company asked close to 1,000 engineers and managers around the world which operating systems they were currently using in their embedded products. The OS appears to be particularly popular in Asia, and the results are all the more impressive considering it’s a commercial operating systems. But Micrium decided to bring more people on board by announcing a free version called µC/OS for Makers targeting hobbyists and startups (<$100k revenues) in February earlier this year. The real-time operating system includes a preemptive multitasking real-time kernel with optional round robin scheduling, has a low footprint (6K to 24K bytes code space, 1K+ bytes data space), support various types of targets including ARM Cortex-M and Cortex-A based MCU and processors such as STMicro STM32, NXP Kinetis, Cypress PSoC5, etc.., as well as Atmel […]

Frosted OS is an Open Source POSIX Operating System for Cortex-M Micro-controllers

Frosted, which stands for “Free Operating Systems for Tiny Embedded Devices”, is an OS with a POSIX-compliant system call API, borrowing the Linux kernel kconfig for configuration, and currently supporting ARM Cortex M0,M3,M4, and M7 MCU including Texas Instruments Stellaris LM3S, STMicro STM32F4/F7, and NXP LPC17XX micro-controllers. The developers are focusing on IoT applications, as well as porting retro-games such as Doom. The kernel relies on libopencm3 for hardware abstraction, and the operating system can be built with GCC ARM for Frosted using the source code released under a GNU GPLv2 license. The Wiki explains how to build and run the OS on either Qemu (in a Linux computer) used LM3S target, or an STM32F4 Cortex -M4 or STM32F7 Cortex-M7 board. The team also uploaded showing a video of Doom (fdoom) running on STM32F7 board, and possibly adapted from stm32doom port. If you are interested in joining the project you can […]

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. […]
