Quesiton about reading data out of EEPROM

Projects Programming
1

I am trying to plot an error signal that my microcontroller is recording. I am logging the data in an array at 100ms samples, the array is in RAM, however after the program is finsihed executing, the last command tells the program to write the data in an array to the EEPROM so I can read it out later through another program. (EACH data point is a byte)

I read it out throught the command line however, I should be getting numebers instead I get symbols which I think are represented by bytes, (MY data).

Command line Sample
Address of EEPROM vs. the byte value. How can I convert these symbols back into the number byte. Is it ASCII or somthing? Thanks

Ultimately all data is bytes, my guess is you're printing it as chars instead of numbers.

Can you post the part of your code where you output the data?

If you look at asciitable.com I am sure you will see they are characters.
try this
Serial.print(yourdata, HEX);
or
Serial.print(yourdata, DEC);

Thank you, I'm going to print out in decimal.
