No puedo hacer ping con un ejemplo que encontré de Mikrobasic
Estoy utilizando el modulo de enc28j60 y el pic 18f4550.
el codigo original en este enlace.
aparece hasta abajo!!!!
Y el codigo que he hecho es el siguiente solo lo cambie para poder utilizarlo con el pic18f4550 y la version 4.1:


Código:

Y Para configurar las caracteristicas del mirocontrolador solo me fije en el ejemplo que trae mikrobasi para pic 18\'s y copie:
Estoy utilizando un oscilador de 8MHz.
1.-la frecuencia :32.000hz
2.-oscillador selection: HS oscilador, pll enable(HPLL).
(Estoy utilizando un oscilador de 8MHz.)
Pdt. No se si tenga que ver, pero al tratar de ocupar el pic 18f4550 para encender un LCD 16*2 no puedo hacerlo, sin embargo simulado si me sale!!!! ...

solo quiten las caritas y habran el enlace para ver el ejemplo:
