Hi guys,

Just a quick question..

At the moment I'm writing to the eeprom after disabling the interrupts.. Do I have to do this?
I want to do long multi-byte (roughly 16 - 32bytes) writes and don't want to disable the interrupts for extended periods of time.

cheers

Hi ub3r,
You don't need to disable the interrupt. Please see below link for the library.

This contradicts this: http://www.lpcware.com/content/forum/lpc1347-eeprom-iap-basic-questions#comment-1123913
Also, I have a timer interrupt going now and my during my eeprom writes and reads and its crashing. Some sort of hard fault as the debugger doesnt like it. :(

Hi ub3r,

The restriction of disabling interrupts only applies when using IAP (=ROM) calls.
When using the library (as pointed out by mc: http://www.lpcware.com/content/blog/lpc1100lpc1300-eeprom-library), this restriction does not apply.

Regards,
Wouter

"Then just link your application to libeeprom.a"
How do we link our app to this? Been trying but cant work it out. :/

It's great that the libeeprom was created, just wishing I could get LPCXpresso project to link with it.

I've followed the manual steps (http://www.lpcware.com/content/faq/lpcxpresso/creating-linking-library-projects) to include the library, but end up with a link error.

<snip>

OK, problem solved. I was including the library with the name libeeprom ('.a' removed per the document). The mistake I was making, the library name should be included as eeprom (not libeeprom). This causes LPCXpresso to include the library named libeeprom.a.
