Store/Retrieve Float to EEPROM TM4C1294XL

Hi,

Use an union composed from an uint32_t and a float. Write the union with float and then use library functions with uint32_t to write/ retrive them.

Some posters will protest against, portability problems, but (hope) will not be the  case here.

For doubles - you got the picture - but do not mix with floats, since you do not have criteria to differentiate them.

Dear PeterI,

Can I have some sample code please?

Girish

ProgramEE(  void *dat, uint32_t offset, uint32_t bytes)

{
    
        (void)EEPROMProgram(dat, offset, bytes);
}

void asdf(void)
{
    double x=3.0;

    ProgramEE(&x, 12, sizeof(x))
}

From memory for EEPROMProgram.

The original EEPROMProgram should have been written with a void * argument not a unit32_t * argument.  It's an outstanding bug in TivaWare.  Easily fixed by a header file change (it even still matches what's in ROM).

A full version of above could/should include checks for sizes etc.. to meet the limitations of storage.
