@FvM
Thank you for your help. After I changed to 4 states it works well. I must have been blind to see that. |

Hello
I am using Timer1 to count my operating hours of the device and store the value every 15 min into the EEPROM. After 71 hours of operating the counter shows me only 57 hours. This is a differ ... |

I changed the code a bit to just write and read 16bit. Now you can call the function for reading:
Internal_EEPROM(0, your_adresse, your_16bit_variable)
writing is:
Internal_EEPROM(1, your_adresse, ... |

Tried both functions and they work fine. Just the LSB are swapped with the MSB compared to my code.
Thanks again for some inspiration and better understanding of C.

Thanks Ttelmah
Now it works the way I want it.
Here my function for copying the bits from a float into an int32. Probably some one else might need it. It might not be the best or the most elega ... |

The union is a good idea. The problem is I have to change a lot of code in my project in order to get it to work. Therefore it would be easier for me to get the float into the int32. I just want to co ... |

Hello
A int32 variable (return_value) is used to store 8, 16, 24 or 32 bits of data. These data will be send via RS232 later. If only 8 bity are stored only 1 byte will be transmitted, if 16 bits ... |

It worked fine after I moved the '&' from your first example in front of DATA. |
