5 CURSO DE C PARA AVR ®´s
En este pequeño curso se tratara de ver un poco como se programan los
Microcontroladores AVR ®'s en lenguaje c, se tratara de abarcar varias partes del mismo,
el curso ira de la mano con la hoja de datos del microcontrolador ya que en esta se
encuentra toda la información necesaria. En este caso toda la información será del micro
ATmega®8 ya que en el estará basada la guía.
