New 32-bit MCUs designed to transform consumer and industrial applications currently using legacy 8- and 16-bit architectures SAN ANTONIO, Jun 19, 2012 (BUSINESS WIRE) -- Freescale Semiconductor FSL +0.80% is now offering alpha samples of its Kinetis L series, the industry's first microcontrollers (MCUs) built on the ARM(R) Cortex(TM)-M0+ processor. Kinetis L series devices are on display this week at the Freescale Technology Forum (FTF) Americas and were demonstrated during the event's opening keynote address. As machine-to-machine communication expands and network connectivity becomes ubiquitous, many of today's standalone, entry-level applications will require more intelligence and functionality. With the Kinetis L series , Freescale provides the ideal opportunity for users of legacy 8- and 16-bit architectures to migrate to 32-bit platforms and bring additional intelligence to everyday devices without increasing power consumption and cost or sacrificing space. Applications, such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control, can now leverage 32-bit capabilities and the scalability needed to expand future product lines -- all at 8- and 16-bit price and power consumption levels. "In our view, 8- and 16-bit development has reached the end of the road. Those architectures simply can't keep up as the Internet of Things gains traction," said Geoff Lees, vice president and general manager of Freescale's Industrial & Multi-Market MCU business. "Kinetis L series MCUs are ideal for the new wave of connected applications, combining the required energy efficiency, low price, development ease and small footprint with the enhanced performance, peripherals, enablement and scalability of the Kinetis 32-bit portfolio." Extreme energy efficiency The ARM Cortex-M0+ processor consumes approximately one-third of the energy of any 8- or 16-bit processor available today, while delivering between two to 40 times more performance. The Kinetis L series supplements the energy efficiency of the core with the latest in low-power MCU platform design, operating modes and energy-saving peripherals. The result is an MCU that consumes just 50 uA/MHz* in very-low-power run (VLPR) mode and can rapidly wake from a reduced power state, process data and return to sleep, extending application battery life. These advantages are demonstrated in the FTF demo, which compares the energy-efficiency characteristics of the Kinetis L series against solutions from Freescale competitors in a CoreMark benchmark analysis. The Kinetis L series is also part of the Freescale Energy-Efficient Solutions program. Kinetis L series energy-saving peripherals do more with less power by maintaining functionality even when the MCU is in deep sleep modes. In traditional MCUs, the main clock and processor core must be activated to perform even trivial tasks such as sending or receiving data, capturing or generating waveforms or sampling analog signals. Kinetis L series peripherals are able to perform these functions without involving the core or main system, drastically reducing power consumption and improving battery life. Built using Freescale's innovative, award-winning flash memory technology, the Kinetis L series offers the industry's lowest-power flash memory implementation. This improves upon the conventional silicon-based charge storage approach by creating nano-scale silicon islands to store charge instead of using continuous film, improving the flash memory's immunity to typical sources of data loss. "The Internet of Things needs very low-cost, low-power processors that can deliver good performance," said Tom R. Halfhill, a senior analyst with The Linley Group and senior editor of Microprocessor Report. "As the first 32-bit microcontrollers to use ARM's Cortex-M0+ processor core, Freescale's Kinetis L-series MCUs will bring the energy efficiency and prices typically associated with 8- and 16-bit MCUs to a broad range of consumer and industrial applications." Development simplicity The Kinetis L series addresses the ease-of-use requirement critical for entry-level developers through innovations including: -- The Freescale Freedom development platform, a small, low-power, cost-efficient evaluation and development system for quick application prototyping and demonstration. It combines an industry-standard form factor with a rich set of third-party expansion board options. An integrated USB debug interface offers an easy-to-use mass-storage device mode flash programmer, a virtual serial port and classic programming and run-control capabilities. -- Processor Expert software, a GUI-based, device-aware software generation tool that eliminates the need to write peripheral start-up code or device drivers. Helps developers easily migrate from 8- and 16-bit to 32-bit solutions by simplifying the software architecture and dramatically reducing application development time. -- The Kinetis MCU Solution Advisor, a web-based application with an interactive MCU product selector that helps identify the best-suited MCU by applying dynamic filters based on operating characteristics, packaging options, memory configuration and peripheral hardware library. Integration and scalability Each Kinetis L series family includes scalable flash memory options, pin-counts and analog, communication, timing and control peripherals, providing easy migration paths for end product line expansion. Features common to the Kinetis L series families include: -- 48 MHz ARM Cortex-M0+ core -- High-speed 12/16-bit analog-to-digital converters -- 12-bit digital-to-analog converters -- High-speed analog comparators -- Low-power touch sensing with wake-up on touch from reduced power states -- Powerful timers for a broad range of applications including motor control The first three Kinetis L series families: -- Kinetis L0 family -- the entry point into the Kinetis L series. Includes eight to 32 KB of flash memory and ultra-small 4mm x 4mm QFN packages. Pin-compatible with the Freescale 8-bit S08P family. Software- and tool-compatible with all other Kinetis L series families. -- Kinetis L1 family -- with 32 to 256 KB of flash memory and additional communications and analog peripheral options. Compatible with the Kinetis K10 family. -- Kinetis L2 family -- adds USB 2.0 full-speed host/device/OTG. Compatible with the Kinetis K20 family. The Kinetis L series is pin- and software-compatible with the Kinetis K series (built on the ARM Cortex-M4 processor), providing a migration path to DSP performance and advanced feature integration. Availability and pricing Kinetis L series alpha samples are available now, with broad market sample and tool availability planned for Q3. Pricing starts at a suggested resale price of 49 cents (USD) in 10,000-unit quantities.

Hello Community fellows! This time I would like to thank BlackNight for giving us great material to work on. There have been several posts inquiring the uses of USB stack and Processor Expert. The examples he has worked on and now shares with all of us, include this and many more useful concepts that you'll find interesting with the use of boards. For this issue he turns his FRDM-KL25Z into a generic USB keyboard device. With a simple button press he is able to send any keyboard actions to his laptop, making such as ‘print screen’ a single button press...isn't that amazing? :smileygrin: Well, I'll say no more, you better check it out yourself!

Hi team : I would like to share an experience to you . Any comments would be welcome . The RTC 32.7668KHz clock can only be sourced from an external crystal that is challenged of some space restricted case . The internal reference clock will be required to support RTC at this moment . Of cause , the IRC accuracy maybe not compete with external crystal , but in this case space is the major concern . However , Kinetis RTC not support clock sourced from IRC . We make a workaround to enable RTC reference to IRC . The detail please refer to attachment . The sample code is build with KDS V3.0 for FRDM-K64F . Best regards, David

Printer extruders and recyclers use Motors that benefit from torque control that can be obtained by using Kinetis V, a BLDC motor and the Freescale Motor control algorithms. A plastic waste extruder for RepRap 3D printer filament. Image: RepRapWiki See this link for more details: How recycled plastic for 3D printing will drive sustainability and improve social consciousness - TechRepublic "Durable, shiny, new plastic -- it's what makes most 3D printers run. And as 3D printing grows in popularity and we begin to scale projects in every industry, the world is going to use a lot more of it. If the industry goal is to have 3D printers in most homes and businesses with lots of other 3D printers running constantly in manufacturing centers, we'll naturally add even more to the 33.6 million tons of plastic Americans toss each year, only 6.5% of which is recycled. It's estimated that 100 million tons of plastic is floating in the world's oceans. Each piece can take anywhere from 500 to 1,000 years to decompose."

En México, el 5.1% de la población vive con algún tipo de discapacidad, de los cuales 23% poseen discapacidades del tipo motriz en extremidades inferiores y superiores (INEGI, 2011). Los métodos que actualmente se utilizan en el proceso de rehabilitación no poseen características integrales en las que el usuario pueda aprovechar la terapia para ejecutar diferentes acciones. El objetivo de este proyecto es el de diseñar y construir una herramienta que permita al usuario no solo hacer ejercicios de rehabilitación, sino que también le ayude a realizar tareas cognitivas o a interactuar con algún medio electrónico (i. e. navegar por internet, realizar trabajos a través de una computadora con Rehab Glove como mouse y/o teclado). Rehab Glove es una herramienta en forma de guante que posee sensores de flexión en las articulaciones de los dedos y de fuerza en las yemas, ubicados estratégicamente con el fin de obtener diferentes valores arrojados mientras el usuario realiza ejercicios de rehabilitación como cerrar el puño o tocar las yemas de los dedos con el pulgar. Estos valores serán convertidos en instrucciones diversas que van desde mover un carro a control remoto, pasando por el control de videojuegos educativos, hasta llegar a tareas más complejas como escribir o controlar el cursor de una computadora sin la necesidad de un mouse o un teclado. La terapia comenzará con el usuario portando RehabGlove frente al elemento que desea controlar, pidiéndole que realice movimientos específicos con la mano para que pueda lograr el objetivo final. Se espera que el nivel de complejidad vaya aumentando en cuanto al tipo de movimientos, rapidez, precisión y fuerza aplicada en cada acción. Con el uso de RehabGlove se espera que las terapias de rehabilitación posean niveles de cognición mayores y que tengan un avance progresivo aumentando el nivel de complejidad en cada ejercicio.

(para español continua mas abajo) Blind deaf-mute comunication system Materials Used : A Freedom- KL25Z card A USB Cable A 16x2 LCD Display Three buttons A breadboard A USB cable Project description Thinking about the difficulties a blind, deaf-mute person has to convey a message, we designed a device to facilitate their communication. Using the Morse key system, the disabled person can write a short message on a LCD screen. For this, you need to press three buttons, and depending on the duration, a function will be performed. 1. If you short-press the button on the left, this will erase the last character typed, however, if you long-press, this will erase everything written. 2. If the middle button with the green label is short-pressed, this will print a dot at the bottom of the screen. If you long press the button, it will print a dash. In Morse code, the dot represents a single signal and the dash represents a triple signal. 3. If the button on the right, with the yellow label is short pressed, the LCD display space will be added to the message. But if he was held down with a longer duration, the set of ¨ Short ¨ and ¨ Long ¨ will be transformed in to a letter in the alphabet and it will be printed on the screen. Note: * If the set of Short and Long does not match any sequence in the matrix, no character is added to the message. **The system to display and write the message on the LCD display are separate. Modifications for the second stage of the prototype 1. Delete button on the right, the yellow label, Send and Space. a. It is intended that the third button is eliminated by increasing the code efficiency. Instead of sending the sequence of short and long pressing a button, they are sent after a desired time interval. b. Wanted to enter the space with a sequence of short and long. 2. Currently the project is divided into two boxes, one that displays the buttons and other writing. The goal is to have a single box which can write and display the message. 3. With a potentiometer seek to change the time it takes to push a button to be recognized among one short and one long signal. Modifications for the third stage of the prototype 1. Perform the division again in two boxes , interconnected by Bluetooth modules , as the system is designed to generate a communication between two people, using a system of sending data to harvest deaf -mute person in the future by Braille . Sistema de Comunicación para Persona Ciega, Sorda y Muda Materiales Utilizados: Una tarjeta Freedom-KL25Z Un Cable Una Pantalla LCD 16x2 Tres botones Una placa de pruebas (protoboard) Un cable USB Descripción de Proyecto Pensando en las dificultades que una persona ciega, sorda y muda tiene para transmitir un mensaje, se ha diseñado un aparato para facilitar su comunicación. Utilizando el sistema de clave morse, la persona con discapacidad puede escribir un mensaje corto en una pantalla LCD. Para esto, se deben presionar tres botones que dependiendo la duración del toque, será la función que efectuará. 1. Si al botón de la izquierda, con la etiqueta azul, apenas se le presiona este borrará el ultimo carácter escrito; sin embargo, si se le presiona con una mayor duración este borrará todo lo escrito. 2. Si al botón del medio, con la etiqueta verde, apenas se le presiona este imprimirá en la parte inferior de la pantalla un punto. El punto representa, un corto en el sistema de clave morse. Sin embargo, si se le mantiene presionado por un momento mas largo, este imprimirá un guión. El guión representa un comando largo en el sistema de clave morse. 3. Si al botón de la derecha, con la etiqueta amarilla, apenas se le presiona, en la pantalla LCD se agregará un espacio al mensaje. Sin embargo si se le mantiene presionado con una mayor duración, se enviará el conjunto de ¨Cortos¨ y ¨Largos¨ a una matriz para que la secuencia se busque y cuando esta se haya, en la LCD se agrega la letra deseada al mensaje. Nota: *Si el conjunto de Cortos y Largos no coincide con ninguna secuencia en la matriz, ningún carácter se agregará al mensaje. ** El sistema para mostrar el mensaje con la LCD esta separado a los botones para escribirlo. Modificaciones para la segunda etapa del prototipo 1. Eliminar el botón de la derecha, con etiqueta amarilla, de Enviar y Espacio. a. Se pretende que el tercer botón sea eliminado mediante el aumento en la eficiencia del código. En vez de enviar la secuencia de Cortos y Largos al presionar un botón, estos se enviarían después de un intervalo de tiempo deseado. b. Se busca que el espacio se introduzca con una secuencia de cortos y largos. 2. Actualmente el proyecto está dividido en dos cajas, una que muestra el mensaje y otra con los botones para escribir. El objetivo es tener una sola caja con el que se pueda escribir y mostrar el mensaje. 3. Con un potenciómetro se busca cambiar el tiempo que se necesita apretar un botón para que se reconozca entre un toque corto y uno largo. Modificaciones para la tercera etapa del prototipo 1. Realizar de nuevo la división en dos cajas, comunicadas entre sí por módulos bluetooth, ya que el sistema está pensado para poder generar una comunicación entre ambas personas, utilizando en un futuro, un sistema de envío de datos a la persona siega sordo-muda mediante el sistema braille.

I’m using the NXP FRDM-K64F board in several projects.One issue I have faced several times is that the board works fine while debugging and connected and powered by a host machine, but does not startup sometimes if powered by a battery or started without a debugger attached. I have found that the EzPort on the microcontroller is causing startup issues. The EzPort is a special serial interface present on some Kinetis, ColdFire+ and ColdFire V2 devices. The issue is that if the EzPort chip select (EZP_CS) is LOW during reset of the microcontroller, it enters the special EzPort mode. The problem is that a pull-up on the EZP_CS line might not pulled up fast enough due capacitance on the line. The commance is if something is not used, disable it! So the solution is to disable the EzPort functionality. That setting is part of the FOPT (flash option register).

Project USB: Connecting USB to CAN with K20 In this project, the internal CAN Controller of the K20 is used to monitor the CAN bus. The connection to the PC is realized by the internal USB Controller. The USB stack is implemented as HID device especially for the K20. The software runs on a self made hardware board. The connection to CAN is visualized with a Qt program, running on every Win7 PC. Result: K20_CAN2USB.zip Original Attachment has been moved to: K20_CAN2USB.zip
