16 Euros Arduino Leonardo Board is Now Available

Arduino Leonardo is a new Arduino board with a 16 MHz Atmega32U4, 2.5KB RAM, 32 KB of Flash memory, 20 digital I/O, 12 analog inputs and 7 PWM outputs. In this version the MCU takes care of USB communication with the host, whereas for Arduino Uno, a separate chip is required to take care of this, which makes Arduino Leonardo cheaper than Uno. Here’s a summary of Arduino Leonardo specifications: Microcontroller – Atmel ATmega32u4 @ 16 MHz SRAM – 2.5 KB onchip (ATmega32u4) Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader EEPROM – 1 KB onchip (ATmega32u4) Operating Voltage – 5V Input Voltage – (recommended) 7-12V | (limits) 6-20V Digital I/O – 20 pins PWM – 7 channels Analog Input – 12 channels DC Current per I/O Pin – 40 mA DC Current for 3.3V Pin – 50 mA Watch the video to get […]

Atmel Unveils XSense Flexible Touch Sensors

Atmel has unveiled XSense, a flexible film-based touch sensor that allows the design of curved capacitive touch screen displays. Atmel expects target applications to go beyond smartphones and tablets, and extend touch capabilities into a wide array of new consumer and industrial products such as watches, coffee machines, calculators and more. XSense touch sensors, based on a proprietary roll-to-roll metal mesh technology, will allow OEMs to develop larger, lighter, sleeker, curved and edgeless designs for smartphones, tablets, ultrabooks and a host of new touch-enabled products, says the company. XSense sensors can be combined with Atmel maXTouch controllers which are already used in numerous smartphones and tablets such as the Samsung Galaxy Note and Samsung Galaxy Tab, as well as other touch controllers available on the market. Here are the key benefits of XSense technology: Flexibility for curved surfaces Narrow border for larger active screen areas Highly accurate stylus performance (active […]

First ARM-Based Arduino Board with Atmel SAM3U

Arduino announced Arduino Due board with a 32bit Cortex-M3 ARM processor on their blog before Maker Faire. The SAM3U processor from ATMEL runs at 96MHz with 256Kb of Flash, 50Kb of SRAM, 5 SPI buses, 2 I2C interfaces, 5 UARTS, 16 Analog Inputs at 12Bit resolution and more. Contrary to previous hardware release, they intend to open the process to the community early on and they plan to to be demo the board and give away some boards to a selected group of developers who will be invited to shape the platform while it’s been created. After Maker Faire, a small batch of Developer Edition boards on the Arduino store will be sold to members of the community who want to join the development effort. The final board will be released by the end of 2011. If you can’t wait there are some other Arduino-like projects with Cortex-M3 support based […]

In-Home Displays for Smart Grid – Atmel – Mentor Embedded

I’ve just attended a webinar organized by Mentor Graphics entitled “In-Home Displays: Enabling Smart Grid into every home” with Atmel and Mentor Embedded. This webinar is now available on-demand at http://go.mentor.com/hAz8 This webinar is divided into 2 parts: Frederic Gaillard – Product Marketing Manager at ATMEL – gave an overview of Smart Grid and its different components and presented Atmel Solutions: MCU/MPU, wireless chips (Zigbee/Wi-Fi) and touch screen chipset. Gordon Cameron – Business Development Manager at Mentor Embedded – focused on the difficulties in developing a user interface for In-Home Displays within a short time frame and how Mentor Embedded UI design solution Inflexion could help greatly reduce the development schedule. There was no external files for this webinar, so I created 2 PDF with the most relevant slides for your reference: Atmel Smart Grid and In-Home Displays Mentor Embedded In-Home Displays UI Development Tools Frederic Gaillard shortly explained the […]
