Hi Everyone,
I'm in need of some direction. I'd like to read and store float values to an .txt similiar to the ascii table example sketch provided. I basically want to store the .txt and send it over a i2c connection to the master computer. But first I just want the values to be stored.
Is this feasible?
Thanks in advance.
Arduino EEPROM just offer support for an unsigned number between 0 and 255 (one 8-bit byte). However, as ASCII char occupy just 1 byte, you could try writing one character on every address of memory. If you are using an Arduino UNO, which has 1024 bytes, you'll be able to write a text of 1024 characters.
I got told the standard eeprom got updated and you can now store floats and ints.
Are you sure? Are you talking about the 328? Maybe there is a new library to write these datatypes, but I don't think that an update can change the size of our EEPROM. Anyway, I think that saving one char per byte is the best think to do, if we need to save text.
P.S. It is already possible to save float or longer integers with a little bit of math.
