external EEPROM QUESTION?

Henrymou

I'm using EEPROM to store a virtual map for a cartographer robot that uses the SX chip. How do I store data in an external EEPROM chip using the SX chip? If I could have a small programming example, it would be great.

Just write to it with I2C statements -- as shown in the help file (hint, hint). There are several demo programs in this thread:

Henrymou,

I am using some great suboutines/functions that JonnyMac wrote to write a word·variable to the EEPROM and read it back. I am using this for my digital·coin bank project·as not to loose the coin value·displayed on a LCD upon a power loss.

(SXB file is also attached).

Like in the other thread that JonnyMac listed:

'Write the coin value eeWord to EEPROM

PUT_EE 0, 0, eeWord



'Read eeWord back from the EEPROM

eeWord = GET_EE2 0, 0

Hope this helps.
