Embedded Graphics Application Design Contest

$10000 cash and development tools will be awarded for best applications using the ST Microelectronics STM32F429 ARM core in the EvoPrimer development platform.  The application must use the Chrome-ART Accelerator graphics technology shown in the video below.  You may add your own custom hardware to the platform if you send it and all the design files with your entry.  For more information on the contest and the EvoPrimer platform go to www.stm32circle.com. The total cost for the base platform and STM32F429 target board is a little over $100 and can be purchased from STMicroelectronics or online distributors.  The contest ends on February 15, 2014.  The grand prize is $5000, and all prize winners will receive Raisonance development tools with no code size limitations and EvoPrimer platforms.

Atmel AVR Hero Consumer Electronic Design Contest

The Are You an AVR Hero? Contest kicked off at Maker Faire a few weeks ago.  Maker Faire is over, but you can still enter you design until December 31, 2013.  This is a Facebook contest and half of the judging criteria is public votes, so you want to enter early.  The other criteria are quality of the idea, quality of the device design, and commercial potential. Here is a link to the official rules.  Click here to vote on a design and click here to enter.


At the time of writing, the design with the most votes (83) is an LED Matrix Tic-tac-toe game using an AVR ATtiny85 on a solderless breadboard.

New Arduino Features 1GHz Texas Instruments Processor

The Arduino TRE Board is coming soon, an official Arduino open source prototyping platform.  Announced today on the TI E2E community site as the most powerful Arduino available to date.  It features the Texas Instruments Sitara AM3359 ARM Cortex-A8 processor.  This is the same processor used on TI's BeagleBone Black. It is clocked at 1GHz, and the board also has 512MB 800MHz DDR3, HDMI, 4-ports of  USB, audio I/O, XBee RF module Connectors and lots of I/O.  For Arduino shield compatibility, it has the shield connectors and also an Atmel ATmega32u4.  This board will also run embedded Linux. It is targeted to prototyping 3D printers, networking hubs for building control, lighting and telemetry, and DIY projects that require more processing power.

STM32F4 Discovery Kit Expansion

The $14 STM32F4 Discovery kit with ARM Cortex-M4 Processor can be expanded with three new boards.  There is a baseboard that provides Ethernet, Micro SD, plus more I/O ($40), an LCD board with touchscreen ($55), and a camera module for video or photos ($34). Schematics and example code are available, see this element14 community page for more information.  The software includes the Micruim uC/OS-II RTOS, a fat file system, and LwIP protocol stack.  The Cortex-M4 processor itself is designed for digital signal control, applications that blend control algorithms and DSP, and require a low-power, low cost solution.

New Microsemi ARM uClinux Starter Kit

Microsemi's SmartFusion2 Starter Kit includes a small ARM SoC FPGA module and a baseboard for user interfaces and expansion.  The kit is $299 but if you attend an Avnet Electronics Marketing Microsemi SpeedWay Design Workshop ($99) you receive a kit at no additional cost.  The SmartFusion2 SoC integrates a 166 MHz ARM Cortex-M3, accellerators for DSP, security and communication interfaces on a single chip.  The Microsemi press release for the starter kit has a nice summary of features for the development board and the SoC itself.


The module itself is an Emcraft Systems mezzanine form factor system-on-module (M2S SOM), you can find more information about the M2S SOM, including documentation and baseboard schematics, at Emcraft's website.  The development sysetem will run uCLinux, and boasts a 0.5sec boot (to console prompt) in this video:

Data Logger Development Boards

In my search for a small, powerful, and inexpensive data logger I came across a few interesting development boards.

PIC32-PINGUINO-MICRO
This Maple-like board features a Microchip PIC32MX440F256H 80 Mhz microcontroller and a 16-channel 10bit ADC (only 11 channels are available on this board).  It can sample at 1MSPS and can perform conversions in sleep and idle modes. The price is very reasonable too at 12.95 EUR (<$18USD).  The UEXT connector allows you to add Olimex modules for a wide variety of peripherals and interfaces.  Modules are available for interface, adapters, sensors, LCD, IO, video, RF. RFID, Ethernet, time, GPS, MP3 and Biofeedback.



FEZ Domino Currently on sale for $29.95 while supplies last which is less than half the normal price.   This board can also be used as an Android ADK platform with it's USB Host port.  It runs the .NET MicroFramework so you can use the free Microsoft Visual C# Express for development.  I am guessing by the low price that this board is being discontinued and replaced by the slightly larger FEZ Panda II board ($39.95).



ADI part number EVAL-ADXL345Z-DB ($59.00)  This datalogger isn't as powerful with only a 40+MHz ARM7-based ADuC7024 MCU, but has a lot of features. The MCU itself has a multichannel, 12bit, 1 MSPS ADC, voltage reference, temperature sensor, voltage comparator, up to 4 DACs, power supply monitor, PLA and 3-phase 16bit PWM generator.  The board can be powered by two AAA batteries, and includes a 3-axis accelerometer, the ADXL345.  The development environment for the sample code requires a evaluation version of the compiler, but there are GNU tools available for the processor. 





One of sparkfun's more popular products, the Logomatic V2 has a simple design and fewer features than the rest and is a little more expensive ($59.95).  It uses the 60MHz NXP LPC2148 ARM7 and you can find a lot of open source code examples on the net.  The board comes with the main logging firmware on Github, and SparkFun's USB bootloader, you can modify the source of either project using free WinARM GNU tools.  Jean-Sebastien Stozel developed a few projects to extend the firmware including a generic C++ multitasking framework using FreeRTOS.
