Hi,

I'm using eZDSP kit. Is it possible to save values when the enery cut off.

I want to use last saved values when I start the system not the initial values.

You would need to use some form of non-volatile memory.

Some memories are inherently non-volatile; eg, EEPROM, FRAM

Some memories are inherently volatile, but can be made non-volatile by adding backup power; eg, SRAM

Thank you Andy.

I think you mean an external EEPROM IC, is it possible use flash memory of CPU.

Mehmet,

Yes you can use the internal flash memory, but keep in mind that you must erase a complete sector at a time.

Software to program the flash is available in controlSUITE in the libs directory.
