Hola:
Estoy probando los ejemplos que tienen www.Microchip.com bajo PIC16F sobre XC8. Este es uno de los ejemplos.
Uso el MPLAB X 1.80 y XC8 con Windows 7.
Al compilarlo pulsando en l aimagen de abajo.
Como respuesta obtengo esto.

...no compila o eso parece. Muestra mensaje como este:

En asm con el PIC16F88 y 16F886 me ocurre lo mismo.
¿Qué es lo que ocurre realmente?
Un saludo.

/**
*******************************************************************
* Lesson 13 - "EEPROM"
*
* This lesson will provide code for writing and reading a single byte onto
* the on-board EEPROM. EEPROM is non-volatile memory, meaning that it does
* not lose its value when power is shut off. This is unlike RAM, which will
* lose its value when no power is applied. The EEPROM is useful for storing
* variables that must still be present during no power.
* It is also convenient to use if the entire RAM space is used up.
* Writes and reads to the EEPROM are practically instant and are much faster
* than program memory operations.
* Press the switch to save the LED state and then disconnect the power. When
* power is then applied again, the program will start with that same LED lit.
* When the lesson is first programmed, no LEDs will light up even with movement
* of the POT. When the switch is pressed, the corresponding LED will be lit and
* then the PIC will go to sleep until the switch is pressed again. Each press of
* the switch saves the ADC value into EEPROM. The PIC uses interrupts to wake up
* from sleep, take an ADC reading, save to EEPROM, and then goes back to sleep.
