How to write an arrray of structs into EEPROM?
PostPosted: Tue Dec 18, 2018 5:22 am     Reply with quote

I have the following type of array:
Code:

typedef struct{
   int16 hr;
   int8 err;
} err_field;
               
err_field my_errors[10];


How to store it in PIC's EEPROM?

Code:
void to_eeprom(char * thing, int8 size, int16 address)
{
    int16 ctr;
    for (ctr=0;ctr<size;ctr++) //loop through the number of bytes
        write_eeprom(address++,*(thing++)); //writing bytes to address++
}

//Then call with
Code:
to_eeprom((char *)my_errors, sizeof(my_errors), 0); //to write starting at zero

Thanks!
And reading from eeprom must be looks like:
Code:

void read_errors(char * thing, int8 size, int16 address)
{
    int16 ctr;
    for (ctr=0;ctr<size;ctr++)
       *(thing++)=read_eeprom(address++);
}


read_errors((char *)my_errors, sizeof(my_errors), EF_ADDR);
