Entrenamiento acerca del Cortex M0+ de la familia Kinetis L presentado por Alejandro Lozano.

Take some time to get yourself familiar with C programming before you continue on the programming tutorial. Here is a list of topics that you should be comfortable with, and a couple of good tutorials below. Topics included: Program Structure Commenting Variables Keywords Data Types Decimal, Binary and Hexadecimal Equivalents ASCII Text/Number Conversion Math Operators Increment & Decrement Shift Logical Operators Bitwise Operators Loops If Statement Switch Statement Functions Recursion Local Variables vs. Global Arrays Pointers Typdef, struct and union Preprocessor Directives Static, const and Volatile Keywords Tutorial 1: PSU Intro to C for Embedded Design   From PSU Freescale Cup Senior Design Course Tutorial 2: Learning Programming with C This Freescale course consists of a collection of lessons that will introduce you to the fundamentals of programming using the C programming language. Coding for Readability Sometimes when a project has the ability to grow with new features, it is best to code in modules. This allows one to easily take a more modular approach to designing their program. Despite the fact that C does not support Classes like C++ does, you can create structures that can be addressed globally with little code, which is especially useful for microcontroller based projects. An example of a structure which will be made global: This goes in the globals.h file typedef struct {   unsigned char ServoPWM;   char ServoAngle;   unsigned char DrivePWM;   int TimeOut;   int Current;   int Speed; } sMotor; extern volatile sMotor Motor; This will go in any other file that we want our structure to be accessible from #include <Globals.h> volatile sMotor Motor; This is how to address the variable in the structure #include <Globals.h> volatile sMotor Motor; If you decided to have two distinguishable motors you could do this in the globals.h extern volatile sMotor Motor1; extern volatile sMotor Motor2; Then do this in the other files volatile sMotor Motor1; volatile sMotor Motor2; Helpful Hints In developing an algorithm to detect the line position, we found two basic errors in the coding practice which caused catastrophic errors in line detection. Both of these tips are very basic coding practice. First, when using C code, it usually benefits the user to initialize all variables to some value, especially if computations are involved. Often times when the value wasn't initialized it would seem to acquire a wrong value seemingly from nowhere. Secondly, when doing calculations with arrays, make sure to do calculations with array indices that actually exist. Many times we would make the mistake in our loops of trying to use an index that wasn't assigned a value. Therefore it would acquire an unknown value from memory that caused errors in our calculations.

One option for mounting the FRDM-KL25Z Freescale Freedom board to the car chassis. [no audio] Important Note:  Secure the wires coming from your motors!!  (I used a zip tie in the video)  If they are allowed to flex at the joint where the wire connects to the motor, it will eventually fail.

Continuing with the "warp drive controller example", this video explains low level hardware interfacing via bit manipulation. An example programming sequence for the warp drive will be shown. View Video Link : 1455

Continue discussion on the line scan camera. A completely interrupt driven approach to the interface will be illustrated.
