radio ID in EEPROM


  • Contest Winner

    At which address does the Radio ID get stored? I want to use the EEPROM on my sensor, but I want to make sure I'm not overwriting

    Pos 0. Have a look in Sensor.h

    #define EEPROM_RADIO_ID_ADDRESS 0 // Where to store radio id in EEPROM
    #define EEPROM_RELAY_ID_ADDRESS 1 // Where to store relay id in EEPROM
    #define EEPROM_DISTANCE_ADDRESS 2 // Where to store distance to gateway in EEPROM
    

    If you're building a relaying node your have to lease space for routing table also (255 additional bytes).

    yes, this part I found:

    #define EEPROM_RADIO_ID_ADDRESS 0 // Where to store radio id in EEPROM
    #define EEPROM_RELAY_ID_ADDRESS 1 // Where to store relay id in EEPROM
    #define EEPROM_DISTANCE_ADDRESS 2 // Where to store distance to gateway in EEPROM
    

    This part, help me to know

    If you're building a relaying node your have to lease space for routing table also (255 additional bytes).

    means only the relaying node needs this routing table, or if I add the relaying capability to a specific device.

    Did you guys plan to reach any deeper into EEPROM in upcoming versions (foreseeable)?

    I'm going to take 125 bytes for a project, but it only a project specific need and I want to make sure that I'm not creating another problem later.

    In this project, I am going to hold some rain history data in EEPROM in case of a power loss for the rain gauge...

    thanks for the help.

    If your write above address 512 you should be safe.

    If you look at the beta version of 1.4 you can see I've added eeprom read/write in the API for sketch usage (that doesn't overwrite any important MySensor stuff). Will make life easier for you.

    cheers mate

    appreciated, as usual.
