25XX1024 EEPROM SPI
PostPosted: Tue Apr 10, 2007 3:09 pm     Reply with quote
Anyone know if the driver for the 25xx640 will work with 25xx1024 or can be modified for the 1024. I am trying to connect to pic 16f917.
After reviewing code it seems like it would work. Has anyone done this!

Thanks!

The 25LC640 driver won't directly work with the 25LC1024. That's
because the 25LC1024 requires a 24-bit address in the i2c protocol,
but the 25LC640 only uses a 16-bit address. So the driver would
have to be modified.

Also, the 25LC1024 has several new commands that should be added
to the driver.
