WARNING If you stumble across the "getting started page" FREEDOM BOARD / CORTEX M0+ GETTING STARTED Please take note: While working with a large number of Freedom boards in a course,  it was observed that the Init Clock Routines would *sometimes* not work.    *Some* of the crystals on the freedom boards do NOT like "HIGH_GAIN" mode.   change the line   pll_init(8000000, HIGH_GAIN, CRYSTAL, 4, 24, MCGOUT); to   pll_init(8000000, LOW_POWER, CRYSTAL, 4, 24, MCGOUT);

The Embedded World 2013 trade show was held last week (26-28 Feb) in Nuremberg. The exhibition attracted over 22,500 visitors (1.3% increase over 2012) of which 29% are from outside Germany. This year, for the 2nd time, Freescale presented its University Programs presentation in addition to its large demo booth in Hall 4A. The University Programs area is dedicated in linking the industry with the universities we partner with, showing demos and achievements from students related to today's Freescale technologies. This year we featured the following demonstrations: ROS (Robot Operating System) communication to a robotic arm and sensor array system featuring distributed computing system based on iMX535 platform from the University of Applied Sciences Georg-Simon-Ohm in Nuremberg Tennis game demonstration as teaching programming tool using the Kinetis K60 Tower system from the University of Applied Sciences of Munich IP Camera stabilisation system for drone system using MPC5604B Track Board from the University of Applied Sciences of Ingolstadt eCARus 2.0 2-seater electric buggy featuring i.MX and 16-bit automotive S12 technologies from the Technical University of Munich Rescue Robot for remote assistance in disaster areas using i.MX and 16-bit automotive S12 technologies from the Technical University of Ostrava FSLBOT mini robot demonstration running on ColdFire from the University of Applied Sciences in Landshut FSLBOT and other student robot projects running on Kinetis K60 Tower systems from the University of Applied Sciences in Deggendorf Here are a few pictures showing robots roaming the grounds and attracting the attention of several visitors. http://www.radio-electronics.com/articles/processing-embedded/embedded-world-2013-the-inside-74

Overview This document has links to videos to give tutorials on how to getting started *from scratch* with the freedom board.    In these tutorials we build projects with bare metal code to see how things work!   It includes the basics on how to get clocks running,  lights blinking and interrupts firing *from scratch*. For more code/peripheral examples that use a "bare metal" approach,  check out the page on the FRDM-TFC board. ERRATA!!!   While working with a large number of Freedom boards in a course,  it was observed that the InitClockRoutines would *sometimes* not work.    *Some* of the crystals on the freedom boards do NOT like "HIGH_GAIN" mode.   The new code is uploaded to this page but you could also change the code yourself:   pll_init(8000000, HIGH_GAIN, CRYSTAL, 4, 24, MCGOUT); to   pll_init(8000000, LOW_POWER, CRYSTAL, 4, 24, MCGOUT); Projects From Scratch for the Freedom Board with Codewarrior 10.3 Projects From Scratch - Part 2 - Importing other projects Using the Freescale Header Files and Blinking the LED Source code for video (Codewarrior 10.3) is in the attached files at the bottom of this document. Clock Distribution Source Code for the Clock Distribution video is in the attached files at the bottom of this document. Interrupts Part 1 - Background Interrupts Part 2 - ARM Systick Timer Source Code for the ARM Systick Timer video is in the attached files at the bottom of this document. Interrupts Part 3 - TPM (Timer Pulse Width Modulator) Overflow Source Code for the TPM Overflow Interrupts video is in the attached files at the bottom of this document

Getting Started with the NXP CUP These pages help you with the question of how to achieve the goal of creating an autonomous vehicle that quickly navigates around a track (timed race) and solves precision tasks (Figure 8, Speed limit zone, Obstacle avoidance) 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 NXP 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… Course Material from the NXP CUP professors and supporters: Thanks to our professors and NXP CUP supporters we created an exclusive starter kit. It includes lecture material, information on the car, useful tips on the board etc. Download the file below and dive into a huge support portfolio! ARC Ingenierie Files - The Champions Board! ARC Ingenierie has been very generous in providing us with their PCB layout and Gerber files to produce your own NXP CUP board. They also provided sample code and drivers plus instructions (in French) to get you started. How cool is that?! Many thanks to ARC, this is much appreciated! Download the files below. If you want to build your own board, please contact us. When do so please keep in mind to give credit to ARC university. All boards should have "HE-ARC Ingenierie" inscription.   Further support links: Information on Line Scan Camera Use The Book of Eli - Microcontrollers, robotics and warp drives Microcontrollers MCU 101 - C Programming for Embedded Systems NXP CUP Shield for the FRDM KL25Z
