• registerUserParms() registers user parameters & format
• registerInitCallbk() resisters parameter initiaziation callback function
  
  
• initWiFiParms() initializes WiFi parameter structure
• initUserParms() initializes user parameter structure calling the registed callback
• saveParms( sel ) saves parameters in EEPROM
• fetchParms( sel ) fetches parameters from EEPROM and populates the WiFi and user data structures, if previously registered. Returns an error code or 0 if all parameters were fetched.
  
  sel can take the following values

HEAD_PARMS to refer to header parameters
WIFI_PARMS to refer to WiFi parameters
USER_PARMS to refer to user parameter
ALL_PARMS to refer to all above
default sel is ALL_PARMS

• getParmsString( sel ) returns a String with a selection of parameters
• printParms( sel ) prints the parameters selectively
• updateWiFiParms(...) defines new wifi parameters and updates eeprom
• updateRebootCount() increments reboot counter and updates eeprom

Define user parm data structure and format

struct { int i1, i2, i3 } us, us0={10, 20, 30};
char *format ="i1=%d, i2=%d, i3=%d\r\n";

main program follows

void main()
{
    eep.registerUserParms( &us, sizeof(us), format );
    
    if( !fetchParms() ) // if EEPROM has bad data, initializes
    {
        eep.initWiFiParms( / Use the defaults / );
        us = us0;
        eep.saveParms();
    }
    eep.updateRebootCount();
    eep.printParms( "Current Parms");
    .....
    // use freely: eep.wifi.ssid, etc
    // use also:   eep.us.i1, etc
    // if you modify, use eep.saveParms()
}
