hi everyone, I have a problem, after another discussion here I tried EM_EEPROM. If I'm supposed to press A, he's supposed to give me the saved temperature values in eeprom, but it doesn't and I don't know why. Can any of you find my problem?
sorry thats the real Discussion, cause i Forget the data.
Best
Marcel

Hi,
I found a few problems with your program.
(1) In save_str_to_eeprom() was not checking the address range
(2) In my previous sample, I always added 0 (NULL) at the end of the string and write data with length of str + 1
But this time null may not have been added.
(3) In get_str_from_eeprom() the length of reading str was not checked,
so it could be (and probably) over write out side of str[] buffer.
(4) I set STR_BUF_LEN as 64, for reading and writing by human, but with format may be 64 was not enough,
so I changed STR_BUF_LEN to 128
Below is the TeraTerm log, and while I was typing this 5LP was reporting Extra Heating Turn off, which I don't know about 😉
