Hi everybody, The original document was moved to KSDK subspace. You can find it in the next link: https://community.freescale.com/docs/DOC-102612 Regards, Carlos

With the HMI developing, touch sensing is more and more popular. The GPIO-based method was developed as a low-cost way to do touch sensing. NXP had developed this sensing method and provide as TSS library (which combines support for GPIO and hardware-based touch sensing).The GPIO method uses the RC charge time in a capacitor (the electrode or touch pad)   Measurement Principles: TSI Method TSI method uses configurable current sources. The current sources are active outputs, making them far more robust against noise. Current sources are configurable, making it possible to configure sampling time. The signal slope depends on the applied current and the capacitance. When a finger approaches the electrode, frequency decreases. Another oscillator, uses a internal unchanging capacitor, this is our reference, we will configure it to oscillate faster than the external one. By comparing how many reference oscillations where counted by the TSI module per external reference scan, we can know when a touch happened.

Producto dirigido para terapias visuales y motrices. Consiste en una matriz de 6x3 LEDs, una columna verde, una amarilla y una roja. Aleatoria mente, se encenderá un LED que se encuentra hasta arriba, y ese irá bajando por la columna de su color hasta llegar al ultimo. Cuando eso suceda, se deberá presionar el botón del color correspondiente. Si esto se realiza correctamente, se suma un punto, de lo contrario se restan tres y suena un buzzer. Los puntos se despliegan en pantalla. La velocidad del juego se puede controlar con un potenciometro y un motor Servo se mueve dependiendo del puntaje.

  Hello Freedom community users Few weeks before, I produced for the Element14 community a full video review of the FRDM-KL46Z including all the steps to program and debug your first project example. Video has a length of less than 13 min so your evaluation of the Kinetis KL46 should be really quick and easy http://www.element14.com/community/community/designcenter/kinetis_kl2_freedom_board/blog/2014/06/17/frdm-kl46z-full-review-and-getting-started-in-video Enjoy Greg

   1.  K60 eDMA 16-channel implementation Local memory containing transfer control descriptors for each of the 16 channels 32-byte TCD stored in local memory for each channel    2.  DMA memory to memory performance In the traditional M2M data movement, performance is best expressed as the peak data transfer rates In most implementations, this transfer rate is limited by the speed of the source and destination address spaces.     3.  eDMA peak transfer rate   4. Performance test         With K60 100MHz (TWR-K60D100M), implement internal SRAM-SRAM eDMA data transfer. If  transfer size setting as 32-bit in TCD Transfer Attributes (DMA_TCD_ATTR), there will has one wait state during each read/write. That's why the DMA performance doesn't up to 200MB/s as the manual stated.       We highly recommend setting DMA transfer size to 16-byte at DMA_TCD_ATTR register, it will much increase the DMA performance.(Get 162MB/s transfer rate with TWR-K60D100M board.) 5.  Testing code attached.

El proyecto está basado en Kinetis KL25Z, consiste en utilizar un tapete de 9 “Botones” y un nunchuck para rehabilitación en piernas y o entrenar sus capacidades sicomotrices llevarlo a cabo atravez de programas especiales en PC, bien esto se lleva acabo utilizando la función de HID de Processor Expert, en el caso del nunchuck funciona como mouse y el tapete como teclado, el joystick del nunchuck actúan como el desplazamiento del mouse y los dos botones con los que cuenta actúan como clic derecho e izquierdo y el tapete actúa como las teclas W, A, S, D, (están son configurables) más 5 teclas adicionales, el tapete está formado por sensores de presión que al pisarlos simulan las teclas correspondientes.     BodyPCcontrol Kinetis Challenge México 2013 - YouTube Original Attachment has been moved to: HID-KEYRUG-KL25Z.rar

To do: Implement a program that lets the 4 LEDs on the Tower toggle all together using the PIT Interrupt. For easy debugging, let the program run in the RAM. * toggle period 0.5 s, * extract vector table and service routines in 'vector.c. Hint: Use the 'arm_cm4.c and 'arm_cm4.h' from the freescale kinetis homepage, which include access functions for the NVIC. For ease of use, these routines are included in the result file. Result: TWR_K60_PIT0.zip

Hello, The below attachment is the code for UART with the input data as a character..But i need the input data to be a STRING...Can anyone please post the code for UART with input as a string using MK22D5.

The KL TSI Library provides the following benefits: • Reduces time to market and development costs. Already available turn-key TSI Library for IH cooker, remote controller applications, etc. • KL TSI is a hardware touch sensing solution, without any additional peripherals, e.g. Timers, GPIO, CPU execution, as a result reduces overall system cost and size. • Enhances reliability by enabling environment adaptive algorithm, eliminating water droplet and stream influence, and filtering electromagnetic interference. • Easy to use, simplifies user interface design. Flexible TSI software library enabling customers to develop an application • FreeMaster1.4 visualizes TSI signal on screen, thus customer can debug and tune touch software simply.

Kinetis芯片在量产时有以下事项需要注意： 1. 保证正确的上电时序，VDD应该先于所有其他引脚上电，VDD上电之前RESET引脚不应该出现高电平。 2. 推荐在RESET引脚加10k上拉电阻，并且和编程器的Reset引脚断开。 3. 编程器至MCU的引线越短越好，最好控制在15厘米之内。 4. 所有引脚不能有超过芯片手册规定之最高电平。 5. 保证焊接温度不超过芯片手册规定之最高温度。

ButtonRace O ∆ []   ButtonRace es un juguete simple, un pequeño invento, que permitirá cambiar la vida de los niños que sufren alguna discapacidad. Nuestra creación está diseñada de una manera muy simple que, a su vez, permite a los niños con capacidades diferentes tener el máximo aprovechamiento. En general, nuestro objetivo era desarrollar los reflejos ojo-mano y estimular el aprendizaje de los niños. Esto, sin caer en las terapias actuales, que al ser tan habituales, pueden volverse menos efectivas. En resumen, el juego consiste en que el niño debe presionar el botón correspondiente a la figura que le es mostrada, lo que permitirá que un pequeña estrella avance a través de una pista de forma determinada. El mecanismo funciona a través del uso de una tarjeta Freedom de Freescale. Además, del uso de una serie de LEDS, un servomotor y algunos sensores infrarrojos y de presión. El sistema está diseñado para darle una retroalimentación al infante, para ver si su respuesta fue correcta. Las figuras encienden en color azul en el momento en que el niño debe presionar algún botón. Dependiendo de si la respuesta fue acertada, la misma figura cambia de color a verde o rojo. Dependiendo de si la figura y el botón corresponden, además, un servomotor moverá la estrella por la pista. Después de varias respuestas correctas, la estrella llegará a una meta, donde el sistema se reiniciará automáticamente. Nuestra intención es que este sistema tan simple de aprendizaje para niños, puede ser utilizado para enseñar otras cosas, además de cumplir nuestro objetivo principal.   Original Attachment has been moved to: Buttonrace.odt

VREF module provide one input pin VREF, this pin can provide reference voltage for both external circuit but also for internal Sigma Delta ADCs, AFE and DAC.  Also it includes trim function in it. In this document, I would like to use my testing to do a linearity analysis. From figure1 and 2, you can find how to make VREF as reference voltage of different analog module. For example, you can find when S1 switches down, S0 closes and S2 select VREF, VREF will be voltage resource of SAR ADC.                                               Figure 1: Voltage reference function configuration                                   Figure 2: Voltage reference module diagramming I do a testing for VREF trim value linear analysis. The process is connecting the voltmeter to VREFH pin, then record measure result for each setting of VREF trim. There will be 64 records for every different setting. Testing chip is MKM34Z256. Please find my testing result from testing data table. From testing result, you can get the formula that y = kx + x0, where k is about 0.005 (5mV) and x0 is about 1.1881, x is trim value.  You can find there is only a little offset from offset curve.                                         Table 1: Trim voltage testing date                                                                 Figure 3: Offset curve

To do: In this exercise, you realize a windscreen wiper with the Tower. The LEDs simulate the moving wiper by running from left to right and back again. The user interface is simple: With pushbutton1, the time delay interval is increased in steps of 1 second starting from 5 seconds delay down to 1 second and further to continuous wiping. With pushbutton2 the delay is decreased in the same way. If the delay is decreased, the wiper should start immediately, because right now there is a need for wiping. This is not true for increasing the delay. In this case, wait till the current delay time is over, set the new delay. In technical terms: Use asynchronous interval reset for decrease and synchronous reset for increase. Use active wait loops instead of the timer in this Kinetis exercise. Hint: Have you already switched a case? Result: TWR_K60_wiper_poll.zip
