JeeLabs: Emulating EEPROM

The LPC8xx series has no EEPROM memory. This type of Electrically Erasable memory is very useful to store configuration settings which need to be retained across power cycles:

But we can emulate it with flash memory, despite the somewhat different properties.

Here’s the why’s, what’s, and how’s of this software trick – in this week’s article series:

• Permanent variables– Wed
• Emulating EEPROM with flash– Thu
• A bag of C++ tricks– Fri

There’s quite a bit of detail involved to get this right, as you will see.
