now in order to store the floating point number you have to convert it to integer format then store this integer format. No, that's not true. You just need to store each and every byte of the floating point number into the EEPROM, and ensure that you read them all back and in the correct order. Probably the easiest way is to have "write-to-eeprom" function that takes 3 arguments: 1. a pointer to the start of the data to write; 2. the amount of data to write; 3. the EEPROM location at which to start writing. And a similar "read-from-eeprom" function. Hint: You don't even need to know anything about Keil's internal representation of floating point numbers - 'C' has a standard sizeof operator... |
