MIAC how to save and retrieve variables from EEPROM

[Claes]

Hi,
Could anyone help me with how to store variables to EEPROM, to be less sensitive for lost power supply.
And after wake-up I want to restore variables from the same memory.

I'm using Flowcode 7 and a standard 8bit PIC MIAC.

Thanks

Hello Claes,

Should be as easy as doing the following.

At the start of your program use the EEPROM read function to pull values from the EEPROM and save into your variables.

Then in your program when you write to a variable you can also write to the EEPROM location.

Beware though because the EEPROM erase/write limit is usually in the 100,000 range so if you change the value just once every second then you will potentially burn out the EEPROM location after 1.15 days.

Thanks Ben,
Sorry but I am a newbie to this. I have tried to find the EEPROM function among MIAC Component macros, but without any luck.
Shall I include a c-code line in Flowcode, and in that case could you tell me the syntax?

Is there a list of all functions available in flowcode for the MIAC hardware?

Best Regards
Claes

Hi,
You need to include the EEPROM component onto your project, then use the Read and Write macros that it has.

Thanks LeighM,
that worked.
