Programming just eeprom?

Started by tadaosystems December 27, 2003
I have a circuit that times and operates a pneumatic device, and is
adjustable via an led menu system. The settings are saved in
eeprom. It is also set up with an in-circuit programmer. Is it
possible to write data just to certain eeprom locations without re-
writing the entire program memory space as well? I almost would
rather have a windows interface that can write data just to the
eeprom so it's possible to make easy changes when near a computer.

IIRC that might depend on the chip you use. And of course on the
programming softwaree. But you can always read the chip, change one
byte, and write back.
