I want to place presets in the internal eeprom which I can access later on with read_eeprom(), but I found nothing if i can do this and how.
I'm using 16F684.
Does anybody know howto do this? |

MPLAB allows you to preset the EEPROM when programming devices.
Or you can preset the locations yourself on boot up by checking for a known "magic" value at a known EEPROM location. If the "magic" value exists, you know that the EEPOMR has already been preset. If no magic value is found, you can load the EEPOMR using write_eeprom().
There are several other threads covering this, so do a search for EEPROM. |

You can also use the #ROM directive. |

I just found out #ROM 0x2100 works fine! |
