So here is the story:
I have several I2C sensors. I do some value reading cycles, then some voodoo magic to do the calibration, and I get 21 parameters (as floats) which I need to save to AT91SAM7128 chip, to store the calibration data, so at next start up I wouldn't need to do the calibration no more, and I could read the value from the Flash memory of the chip and use them further in the program. If I compile it now everything compiles ok, no errors. But then I add this code to function definitions as suplementary code:

Another thing is how to correctly modify the read and write functions mentioned in the code above, to store and read floats??
Many thanks for your answers,
