Conexión para el puerto paralelo:

  Connect AVR with parallel port
        AVR                       Parallel Port
   Signal name   Pin             Pin  Signal name
   GND           20 ------------ 19   GND
   GND           20 ------------ 21   GND

===== Puerto serial =====

  - Niveles de voltaje
  - Rx, Tx

===== Temas de C =====

  - int main(int argc, char** argv, char** env)
  - for if while
  - printf
  - hello, world
  - getchar, putchar
  - ++n;
  - Comparaciones == != >= <=
  - arrays int narray[10];
  - call by value (arguments are copied) (local copy) (local copy can be modified)
  - character arrays char string[size];
  - local variables (functions), extern and global variables
  - types and sizes (int, char, float, double) (short, long) (signed, unsigned)
  - declarations, definitions (vars funcs)
  - const (don't change)
  - + - / * aritmetica
  - casting
  - ++n n++
  - bitwise | & ^ << >> ~ 
  - += assignment
  - precedence page 50

  switch (Expt) {
     case const: statements
     default: state
     }

  -  do while 
  - break, continue
  - functions return
  - header files .h
  - static: for external variables makes them unaccesible from users, for local variables, makes them permanent for functions
  - initialization int x=1;
  - #include, #define (preprocessor)
  - pointers, arrays
  - & address
  - * to declare pointes, and to resolve pointer data.
  - pointers and function arguments
  - structs
  - typedef int length;

  struct point {
    int x;
    int y;
  };

  struct point pt;

  * sscanf
