Estoy recibiendo el error de símbolos indefinidos en XC8 para dos arreglos de estructuras declarados como externos en el archivo io.h. ¿Por qué sucede esto?

score 2 · Accepted Answer

Hay una diferencia entre declarar una variable y definir . Has declarado que debounce[] y input[] existen en otro lugar mediante el uso de la palabra clave extern , pero en realidad no las has definido en ninguna parte (al menos eso Podemos ver en el código provisto).

Para corregir simplemente el error, puede definir las matrices en su archivo io.c. Pero por lo que puedo decir, debounce[] y input[] no se usan en ningún otro lugar en su programa, por lo que no es necesario exponerlos en el archivo de encabezado (es decir, definirlos en el archivo io.c y eliminar el extern de declaraciones del archivo io.h).
