Basic Stamp and data EEPROM Read/Write
Archiver
Posts: 46,084
Does anybody have experience with writing data to and
reading data from the Basic Stamp 2 EEPROM?
First I write some data to known positions at the
EEPROM. Then I start reading and checking them in the
debugging window, but only the first two are correct,
and the rest is corrupted. Also in the same moment
there are problems with the program execution, it
loops without an exit...
Has somebody an idea what is going on?
Thank you in advance.

are all stored in the same eeprom). To check where your program code
stored in the eeprom ends, check the memory map. Then start writing
your variables to the eeprom only at addresses after your program
code.

plenty of space at the beginning of the EEPROM map. So
I am sure that I am not overwriting anything - I keep
a look at the EEPROM map all the time.
Is there something else that can be hapenning?
