Pulse-width modulation (PWM), is a technique utilized in robotics for controlling motors and servos. Through the use of internal counters, the microcontroller modulates the duty cycle of a square wave to control the amount of power delivered to a device. The Duty Cycle referes to the porportion of time the square wave is 'on' as compared to the repeating signal period. The higher the duty cycle the higher the power carried in the signal. Duty cycle is expressed as a percentage of time the signal is 'on', with 100% being consistently on. overview-create-a-pwm-signal Once you feel comfortable that you understand the concepts behind a duty cycle signal, return to Reference Manual: Timer Information portion of the Drive A DC Motor Tutorial

Many companies run the risk of animals such as rats and variety of insects invading plants or warehouses, where the products are liable to be contaminated, mainly food industry companies. For the above, we come up with the development of the “pest control using Freescale” which consists of implementing an electronic device that emits ultrasonic frequencies ranging from 30KHz to 65KHz generated by the FRDM KL25Z board transmitted by a buzzer and through an interface may change the operation time of our prototype. Therefore purpose of this project is to solve the pest problem in a "green way" to avoid damaging the environment. Original Attachment has been moved to: Pest_control_using_Freescale.rar

Project Summary In this project, you will learn how to do basic electrical automation and control via the web. Think of the NEST.... only more open and hackable! Using Websockets, Javascipt and HTML5, you will have a simple way of viewing remote data and be able to control some solid state relays. This framework will allow you to create more complex IoT applications. The example will combine a FRDM-K64F and a FRDM-AUTO to read a temperature sensor and control a solid state relay. Skills Developed: Embedded Systems Networking Electrical Control Systems HTML5/Javascript - Websockets SOIC8 and 1206 Surface mount soldering Internet of "Things" Materials: FRDM-K64F FRDM-AUTO Development Tools mbed.org Google Chrome Notepad++ Example Code mbed.org Github Step 0: Prerequisite Videos The videos are organized into a nice YouTube playlist: FRDM-AUTO Hardware Overview MonkeyDo Software Overview Websockets & The MonkeyDo communication model Solid state relay introduction & sage Opto-coupler introduction & usage MonkeyDo system demonstration Step 1: Get a FRDM-AUTO & FRDM-K64 The build package is on the FRDM-AUTO site. Note that for this exercise you only need to build the "OPTION 1" version. Please let us know if you are interested in a pre-assembled version. If there is enough demand we will get a lot assembled for purchase, I will get a Kickstarter going! Don't be afraid to build it yourself, Soldering is fun! There is plenty of good stuff on the web on how to do SMT soldering. All of the parts on the board are fairly simply once you get the hang of it and everything can be hand soldered The key is having some decent tools. Step 2: Put it Together Assemble the FRDM-AUTO and K64F. When you get started, do NOT hook up anything to the solid state relays until you are sure things are working. WARNING: Wiring to household power can be dangerous! You are 100% responsible for what you do. Be careful and never apply power until you fundamentally understand what you are wiring up! Step 3: Download If you have never used the mbed environment, make sure to careful read this page. Get the "blinky" programming working before you try anything else. Download the example firmware to the FRDM-K64F. Make sure to press the reset button. Step 4: Follow Along Make sure to watch the demo video. Load the example javascript pages from the github repo and recreate what you see in the demo video. Note: You should NOT use the websocket server used in the demo code. When you register for an mbed account, you automatically get your own websocket server channel. See Websocket server by Mbed. Step 5: Hack and Slash! Make something cool! Be cool and publish your work! Some Ideas to Extend the System Get the opto-couplers into the Websocket system and see if you can report their state Make a basic thermostat using the temperature sensor and relay to control a heater. Report status via the websockets interface

We are thrilled to present to you, the newest member of our Apalis family of ARM powered computer-on-modules, the Apalis iMX6. The module is based on Freescale i.MX 6 series of System-on-Chip (SoC), runs an ARM Cortex-A9 CPU, and offers an operating frequency of up to 1.2 GHz. Apart from the benefits of long term product availability (of more than 10 years), and compatibility with the existing Apalis T30 module, this module is also qualified for industrial temperature range -40° C to 85° C. More details including datasheet shall be published by the last week of February. For a preliminary datasheet, click here. For more details on Apalis family, click here. To know more about the Apalis T30 module, click here. Here's a first look at the module.

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.

Depending on which MCU Devlopment board you have chosen, you will need to figure out a way to mount this to the chassis. I have seen everything from cardboard, to aluminum, to wood. Below is a template complete with CAD drawings to mount the Qorivva TRK-MPC5604B board and the Motor Board onto the chassis. We use plexiglass for ours, but any other millable material is appropriate. The large hole in the middle is for cables from the servo. We attach the board to the car using the plastic standoffs (you will need them 55 mm long, so in our case, we used the combination of 40 + 15 mm) - see an example (SOS code 10260). To attach both the processor and interface boards the simillar 5mm plastic standoffs were used. Preview (.pdf) CAD file (.dxf)

Features General Tower card Form Factor Connections to allow use with a TRK-MPC5604B Board Camera Interfaces 1. 5-pin header to connect directly to Freescale Line Scan Camera 2. Header for 2nd linescan camera (optional) 3. RCA Camera Interface. Includes an LMH1981 Sync Extraction chip and connectors to MCU to allow for low resolution (32x32) decoding of signals Servo Outputs 3-pin Header to connector directly to steering Servo 1 Extra Servo header. Power Accepts direct Battery Power – Onboard Switching regulator 5-18v Tower Card will source power to other tower modules. All circuitry except for motor controller can be optionally powered over USB Connector Battery Input and motor Outputs will be a Tyco (TE Connectivity) TE Connectivity Screw Terminal http://search.digikey.com/us/en/products/1776275-2/A98036-ND/1826899 Motor Driver 2x MC33887APVW : Dual, Independent 5A Motor Driving Circuit Supports forward, reverse and braking. Current Feedback to MCU ADC to allow for closed loop torque control Programming Integrated Kinetis MK20DN512ZVLL10MCU with OSJTAG Can be used stand-alone or be used as a peripheral in the tower system. Additional I/O Extra signals from K40 routed to tower edge card connector. Signals for H-bridge, camera and servo can be routed to Tower Edge connector to be driven by another MCU card. Each can be disconnected via jumper. - We will need to crosscheck the signals to all other CPU modules. Would it be easier to just have a version that doesn't have the K40 populated and OSJTAG populated? Also, we may not need jumpers. Simply configure the Kinets I/O to inputs. Some basic I/O for debugging. 4-poistion DIP Switch + 4 LEDs. Inputs for Tach Signal/Speed Sensor Design Files Rev Alpha Schematics (Sent to MyRO on 4.4.2012) - Includes 3d view Assembly Prints (For Reference) PCB Fabrication Notes Bill of Materials Rev A Errata: Pins 4 & 5 for the camera (Gnd and +3.3v) got swapped on the PCB. You will need to swap the wires in the cable. You can pop the contacts out of the connector housing with tweezers. POT0 has a jumper wire to pin 26 (ADC1_SE18 . This was done to put all signals *except* the NTSC video onto ADC1 to simplify software. Future versions will have this change in the artwork Some components interfere with the tower connector. It can be mated to about 95%. Will work fine. Future versions will fix this issue Rev Beta Schematics, Assembly Prints, BOM, etc. - Includes 3d view Rev B Errata: None known! Google Code repository for the Example Code: https://code.google.com/p/tfc-twr/ This code works with Rev B of the board (and Rev A). All major interfaces & peripherals have been tested. At some point we will make a video going through the code. By default the Linescan camera code is enabled. The code in Main.c is pretty easy to follow. There is also code for the NTSC camera but must enabled in the TFC_Config.h file via a pre-processor directive. There is also code used for teh OSTAG interface, Labview demo applications and drivers for the USB Pictures Just verified the OSJTAG. Test Project to blink the battery LED's was downloaded into the K20 Videos Testing the Servo circuits….. Testing the pots, servos, H-bridges and K20 USB port Linescan Camera Bringup with Labview NTSC Camera Bringup with Labview 1.) This is a basic demo of an NTSC camera being brought in using the a Combo of the ADC, port interrupts and DMA transfers. 2.) I *ahem* overclock the ADC to 24MHz to get some extra resolution for a 64x64 pixel image (the first 6 columns are junk as they contain color burst data*) 3.) I decimate the images to a few frames per second to send over the WIFI (the booster pack card I made) to a Labview program. The Kinetis can bring the data in a the same frame rate of the camera, I just need to send much slower as there is some overhead in my communications scheme (ASCII text) and the WIFI is driven via a UART. 4.) In reality, I can get a 64 x 480 pixel image in memory as I pull in all the lines. I just decimate the rows to get a 64x64 result on the labview display. 5.) DMA does most of the work freeing up the CPU to do algorithms in the foreground.

First and foremost, be creative!! Below are just a few inspirational ideas. Option #1 - I cut-down (miter saw) a 4-position TWR-ELEVATOR to make this 2-position design. With the intent of having two boards mounted 1) TWR-PROTO and 2) MCU of choice (K40). If cutting PCB's with power tools is not your thing, you can buy a 2-position Tower Elevator here: http://wavenumber.net/twr-elev-2/ I just marked the holes on the back supportand drilled holes into the TWR-PROTO, a few stand-offs and viola! Option #2 - This option requires the removal of the rear spring. I am not sure how much value that spring honestly provides since most of the track is nice and flat. If you have a newer TWR-ELEVATOR you usually find some way to mount it to the screw holes with some form of L-Bracket. If you have an older TWR-ELEVATOR you can drill a hole in the Secondary Elevator (less PCB traces to worry about) and then mount it to the chassis with a L-Bracket. Option #3 - Check out this gallery of images: https://plus.google.com/u/0/photos/106056936857240793028/albums/5598207628299505201

Getting Started with the Freescale Cup How to achieve the goal of creating an autonomous vehicle that quickly navigates around a track? Before continuing with this tutorial, students should take the time to choose which Freescale Microcontroller your team is going to use. The Introduction to Freescale Cup Training article has some details about how to choose your microcontroller. Although the concepts and end results are similar no matter which microcontroller you decide to utilize, much of the software implementation details will differ. What is a Microcontroller? For information on what a microcontroller is head to the microcontrollers article. Getting Started - Learn to Program a microcontroller First off, you are going to need to know C programming. For a crash-course head to c-programming-for-embedded-systems. The classic first application to learn how to program a microcontroller is to get through the process of Blinking an LED. This wiki contains a tutorial for each of the Cup microprocessors which simplifies the process of setting up the evaluation board, installing the Integrated Development Environment, and programming the board with a simple set of software which blinks a LED. The Blink a LED tutorial is the first of 4 tutorials designed to familiarize students with the process of designing a cup car. These four tutorials will introduce students to many of the fundamentals of robotics, the software used to control the locomotion and sensors on an autonomous line following vehicle, and provide example code which help simplify the process of creating a competitive entry in the Freescale Cup. Here is an outline of the Basic Microcontroller Programming Tutorial: Read the microcontroller article Choose a microcontroller Set up the development environment Set up the microcontroller evaluation board Program A LED move to the next tutorial…
