Leonardo just started a new blog where he will talk about electronics including Atmel MCU (ATMega, XMega,..) and ASF (Atmel Software framework) with articles and examples. Blog is in Italian :) but also a computer-translated version is available. Check it out…

American Semiconductor has announced the FleX-MCU product family. The new FleX-MCU device is the world’s first physically flexible microcontroller fabricated using the manufacturer’s FleX silicon-on-polymer process. It is an 8-bit RISC device with 8 KB embedded RAM operating at up to 20 MHz, with a 1.2 V core and 2.5 V I/O. It features several serial interface peripherals, including UART, I²C and SPI.

FleX-MCU is the initial product of a family of physically flexible ICs. The FleX IC roadmap includes microcontrollers, analog-to-digital converters, RF wireless communication devices and non-volatile memory.  [via]

USBTiny-MkII SLIM programmer (AVRISP-MKII clone) supports all Attiny, Atmega, and Xmega µcontrollers. It has three programming interfaces: ISP, PDI, and TPI. It works with AvrStudio or AvrDude. Small convenient board, contains double direction voltage translator for all interfaces and working from 1,2V, jumper for target chip voltage selection 5V or 3,3V (LDO stabilizer), and status LEDs. The heart of the device is a AT90USB162 controller with hardware USB, so it can provide fast programming speeds.

Tutorial: Getting Started with the LPC810 @ The Adafruit Learning System.

This learning guide will show you everything you need to know to get started with the ARM Cortex M0+ based LPC810 MCU. It will cover:

  • Setting up a cross-compiling toolchain for ARM
  • Creating and compiling your first blinky program
  • Programming the LPC810 using free and open source tools

Philip Peter writes:

I always like a challenge, so when I saw [simpleavr]s vusbtiny programmer, I started to wonder how small I could make an AVR programmer. All in all I’m pretty pleased with the result.The schematic is almost the same as the original one. I only added a LED an resistor to indicate a proper power supply.

Guan Yang of HackManhattan writes about his efforts working with a Bluetooth low energy component:

This amazing component is the Nordic nRF51822 that was released last year and is now available for order from Mouser. It’s a Bluetooth Low Energy system-on-chip that includes a transceiver and a Cortex-M0 microcontroller.Here’s a breakout board I made for it, using a Johanson balun and chip antenna. It takes a little help from the Internet, but I got it to work with Nordic’s SDK and the gcc-arm-none-eabi toolchain. Haven’t tried debugging yet.

Raj from Embedded Lab posted a new PIC project which is about building a mono color LED matrix marquee that consists of 320 LEDs in total that are arranged in 8 rows and 40 columns. The project uses PIC16F1847 microcontroller which receives the display data from a PC through a serial interface, and display it on the LED matrix scrolling from right to left.

The Aithon board is an integrated robot controller board with a 32-bit ARM microcontroller and a powerful software library.

The Aithon board is a microcontroller board that combines the power of a 32-bit ARM Cortex-M4 with several integrated features that make robot building and experimentation fun. We set out to create a board that has more processing power and memory than the typical Arduino, yet has integrated hardware that you would not find on a Raspberry Pi.
