hola gente .. bueno trate de pasar de un micro attiny2313 a atmega8515 ... y al cambiar el micro en la compilación original .. creo que cometo un error y no se cual es ... porque me larga la siguiente advertencia """ AVR Simulator: Excessive stack overflow, stop sim
"""" la librería original es esta
la cual yo cambie los PORT y el cristal para el atmega8515 ..tal vez cometi algun error mi librería es esta """
tambien subo el proyecto completo del atmel estudio 4.13 dentro de el esta la libreria original ...gracias
"""" la librería original es esta
