CHANDLER, Ariz., Oct. 17, 2011 [NASDAQ:  MCHP] — Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, and Digilent®, Inc., today announced the availability of a Microchip dsPIC33 Digital Signal Controller (DSC)-based development kit.  The Digilent® Cerebot™ MC7 Development Kit addresses the growing interest in embedded motor control from the academic and hobbyist markets, and is ideal for learning about microcontrollers and solving real problems.  The kit includes a demonstration board that provides four half-bridge circuits, eight RC servo motor connectors, the ability to use Digilent Pmod™ peripheral modules, and an integrated programming/debugging circuit that is compatible with the free MPLAB® IDE.  Example applications include university embedded-systems and communications classes, senior capstone projects, and numerous other academic and hobbyist projects.

video demo of the kit can be viewed on YouTube at (feel free to embed on your Web site):http://www.microchip.com/get/8HF8.

The Cerebot MC7 board features four half-bridge circuits that are rated for 24V at up to 5A. These half bridges can be used to control two Brushed DC motors, two bi-polar stepper motors, one Brushless DC motor, and one uni-polar stepper motor.  An onboard 5V, 4A switching regulator with an input voltage up to 24V simplifies operation of the board, enabling it to operate from a single power supply in embedded applications such as robotics.  The onboard dsPIC33 DSC features 128 KB internal Flash program memory and 16 KB internal SRAM, as well as numerous on-chip peripherals, including an advanced 8-channel motor-control PWM unit, an enhanced CAN controller, two Serial Peripheral Interfaces (SPIs), timer/counters, serial-interface controllers, an Analog-to-Digital Converter (ADC), and more. The Cerebot MC7 board combines two push buttons and four LEDs for user I/O, as well as connections for two I2C™ busses, one of which contains an integrated serial EEPROM device.

“The Cerebot MC7 board is an ideal embedded motor control and general-purpose microcontroller experimentation platform for academics and hobbyists,” said Clint Cole, president of Digilent Inc.  “It's our latest entry in the engineering education market.”

“We continue to see an interest in advanced robotic applications in the academic and hobbyist markets,” said Cheri Keller, Sr. Manager of Microchip’s Worldwide Academic Program. “The Cerebot MC7 board is ideal for these types of applications, among many others requiring the advanced motor-control peripherals found on Microchip’s industry-leading dsPIC33 DSCs.”

Linux en Javascript, en tu navegador web, con almacenamiento local

Linux en Javascript, en tu navegador web, con almacenamiento local: NOTA: Fuente de este artículo: eliax.com por autor José Elías.

Linux ShellEsto es algo sorprendente para usuarios técnicos (yo mismo quedé anonadado), pues ahora gracias a un emulador x86 implementado en Javascript, ahora es posible ejecutar Linux en su más reciente versión (3.0.4) dentro de tu navegador web, con Javascript.

Tan sorprendente como el hecho de que está implementado en Javascript (ahora mismo lo estoy utilizando en el navegador Google Chrome), es el hecho de que puede almacenar información localmente en tu máquina, gracias a las facilidades de Local Storage que provee HTML5.

Eso significa que puedes hasta cerrar (o incluso reiniciar tu máquina), y las cosas que hayas almacenado en tu instancia de Linux en tu navegador web continuarán estando ahí.

Asombroso.

Nota: Esto es similar a este otro proyecto de Linux con Javascript, con la diferencia de que el nuevo proyecto permite almacenamiento local.

Vamos a ver si ahora si es cierto tanta belleza. Todos esperamos la famosa plataforma de 32 bits a un costo razonable y sobre todo una realmente compatible con arduino. Ya hace un tiempo esta en el mercado la plataforma Maple de leaflabs con procesador STM32 ARM Cortex-M3, sin embargo la complejidad de esta máquina hace que las librerias se hayan demorado mucho en aparecer a la vez que pierden eficiencia en el proceso. Al parecer falta todavia para la compatibilidad al 100%.

Esta plataforma es fabricada por Digilent (un partner autorizado), viene en en las dos versiones el uno32 y el max32 (similar al mega). Según entiendo la "compatibilidad" consiste en que escribieron un entorno igual al arduino con la opción de compilar para arduino. Igual si las cosas salen bien y arduino no contrataca en mi opinión esta plataforma seria un verdadero monstruo y podria barrer el mercado dado su muy bajo precio, su velocidad de 80 MHz y la calidad de la máquina.

Bueno les dejo el link para que sueñen un rato. http://www.neoteo.com/chipkit-el-arduino-de-microchip
