Title: Non-volatile nano memory where are you
Post by: cch1955 on August 18, 2011, 02:46:24 PM

I understand the nano does not have EEPROM and that FRAM is optional. In the installation guide on page 1-7 it states:

Non-Volatile Data Storage
Integers (16-bit)
Strings (40 chars max)
1024 words

I need a small amount of nonvolitile memory for my application parameters and was planning on using the above 1K

How to do you read/write the 1K nonvolatile integer memory?

Please read Nano-10 User's Manual Page 1-8 regarding using the 1024 words of pseudo EEPROM.

Briefly speaking,  you would use the SAVE_EEP and LOAD_EEP as if they are EEPROM. But the data saved with SAVE_EEP are written into temporary static RAM location and will not be saved into non-volatile memory until you run the SETSYSTEM 252, 0 function which update all 1024 words to flash memory in a single action.
