A look at interrupts in a microcontroller from a generic point of view. This will be used to put the other videos relating to interrupts of the ARM core in context.

Illustrates some basic concepts with respect to microcontroller design tools. A generic design flow will be introduced to orient the audience to the most common steps in the software development process.

25 student teams from 21 universities coming from 11 countries will meet on 29-30 April for the Freescale Cup EMEA Challenge. Check out the event information at https://www.facebook.com/events/1425416907713292/

Freescale Cup China - Two Wheel Self Balancing Challenge 2012 In China they have another tier of competition in which the cars must complete the track autonomously while balancing on the rear wheels. For this challenge they use a charged wire in the track for which to sense and navigate the vehicle by. Really cool!

Data acquisition system for Kinetis K Family Author : Mauro Padin (Student) Supervisors : Professor Daniel A. Jacoby, Juan Pablo Vega (Teacher Assistant)   Summary:   This project is based on the FRDM-K64F board, a HC-05 Bluetooth module, and a smartphone. In this application, an analog signal is sampled and transmitted wirelessly to a smartphone, using an external Bluetooth module, where it is displayed. The complete CodeWarrior C code and MIT App Inventor code can be found in the .zip file. System Structure SysTick Module: Periodically triggers ADC conversions and UART transmissions. ADC Module: Samples the analog signal and manages the ADC input buffer. UART Module: Manages the UART output buffer and transmits the digitized data. Bluetooth Module: When connected, wirelessly transmits the data coming from the UART module. Smartphone App: Handles Bluetooth connection, receives the digitized data and manages the display.   Software Structure   A project template is provided to the students in order to establish a simple, and easy, program organization for the duration of the course. A portion of the template was built with the help of the Processor Expert so that, later on, the students would be able to understand its structure and limitations, and transition to this new tool. A wrapper was built around this auto-generated code and the resulting function, void __LDM_init (void), is to be used at the very beginning of the project given. This function mainly configures internal processor registers related to clock configuration.   The project is composed of separate files for each hardware and software module:   The template is composed of four files: LDM.c/h, main.c, and misc.h. The application is found in: App.c/h RTI, ADC, UART, LED Drivers are defined in: RTI.c/h, adc.c/h, uart.c/h, and LED.c/h.   The basic Driver structure consists of a void DRV_init(void) initialization, a set of void DRV_x_ISR(void) interrupt handlers, a set of void DRV_x_PISR(void) periodic interrupt handlers, and a set of void DRV_x services function. Only the initialization function is mandatory, the others being optional and dependent on the driver purpose. Service functions are interfaces between the application and the Driver and do not necessarily access any subjacent hardware. Indeed, this Driver structure can be nested and thus not handle any hardware at all. When a Driver function does access hardware, it is recommended to further use a Hardware Abstraction Layer to enhance productivity and improve portability.   Extracts of the system   As an example of the Driver Structure, the LED Driver is described below:   init void LED_init  (void)   ISR N/A   PISR void LED_PISR  (void)    Services void LED_write  (color_t color, bool value) void LED_set  (color_t color) void LED_clear  (color_t color) void LED_toggle (color_t color)   The entire application is interrupt driven, so that only initialization are necessary and the run loop is empty:   void App_init(void) {   LED_init();  // LED driver init function   uart_init();  // UART driver init function   adc_init();  // ADC driver init function   RTI_init();  // RTI driver init function }   void App_run(void) { }       Hardware interrupts are not serviced in their specific handler but referred to external handlers for readability and organization. The SysTick interrupt handler is composed of a ISR and a Service:   ISR_t SysTick_Handler(void) {   LED_isr code   ADC_conv code } The code for the smartphone side is depicted below:     Finally, a screenshot of the result:       Original Attachment has been moved to: -ADC-bluetooth-TP6.zip

Lecture 1: Introduction and Motor Basics  This training module presented by Professor L. Umanand of CEDT, Indian Institute of Science, Bangalore provides an overview of the Freescale Cup – 2011. It introduces to the challenge describing the various components of the intelligent car tracker. Lecture 2: Pulse Width Modulation  This lecture provides an overview of Pulse Width Modulation Lecture 3: Control Design  This lecture describes controller design and PID control Lecture 4: Speed and Position  This Lecture discusses integrating your PID with sensor data Lecture 5: MPC5607B Overview  This training module provides an overview of the 32-bit Qorivva MPC5607B Processor. The course is targeted towards beginners in order to enable them to quick start the development of software on the MPC5607B.

32-bit Kinetis MCUs represent the most scalable portfolio of ARM® Cortex™-M4 MCUs in the industry. Enabled by innovative 90nm Thin Film Storage (TFS) flash technology with unique FlexMemory (configurable embedded EEPROM), Kinetis features the latest low-power innovations and high performance, high precision mixed-signal capability. For the Freescale Cup Challenge, we have provided several tutorials, example code and projects based on the twr-k40x256-kit. This board is part of the Freescale tower-system, a modular, reusable development platform that allows engineers to quickly prototype new designs. The K40 chip is a 144 pin package with 512KB of Flash, 245Kb of Program Flash, 4KB of EEProm, and 64KB of SRAM. Important Documents: Reference Manual Besides the Reference manual and the Datasheet, the most useful document for learning to program the K40 chip is the Kinetis Peripheral Module Quick Reference Data sheet Errata External Links Freescale's Kinetis K40 Product Page

     El juguete consiste en 3 botones de un tamaño adecuado. Cada uno precederá a una tira o serie de leds. El programa ejecutará una instrucción que creará una secuencia de valores aleatorios, los cuales, por así decirlo, descenderán por las tiras de leds. El niño tendrá que presionar los botones en el tiempo en el que la luz alcanza y permanece en el botón. Muy similar al videojuego Guitar Hero. El aumento de dificultad es mediante el aumento de la rapidez de juego; será regulada según la posición de un potenciómetro. También será posible decidir el número de botones a usar.      El modo de uso no se limita a las manos, podrá ser usado con los pies sin problema alguno. Para hacer eso posible cada botón será independiente de los otros dos, lo que permitirá el acomodo más ergonómico de los botones según las limitaciones de movilidad del niño. Para evitar el desplazamiento de los botones por la superficie: suelo, alguna mesa... los botones se fijarán a un tapete de Velcro.
