Hello
Im using the function
EEPROM.write(20,var);
But if i use a too high value of numbers to write into EEPROM, its not working!
for Example
var= 10
is working
var= 1112
is not working
how can i fix this? i need to store a value into eeprom that can be 0 to about 4000.
EEPROM is byte values (0-255), for larger numbers you would need to use two bytes. Check out this post for some ideas..
research EEPROMex it lets you read/write byte/int/float and its easy to use
In the latest version of the EEPROM library, you can use EEPROM.put( address, value ) & EEPROM.get( address, ref ) instead of read() and write() for anything bigger than a byte (structures too).
There are more features I'm adding to it, however this one is already implemented in versions 1.6.2 and above of the IDE.
that's good to know.
