EEprom Help

[JLeith]

Hi All

Need a liitle guidence on EEprom action.

I was reading posts and think I have it correct but the value is not storing in the EEprom.

Here is my events
The train runs loop 1 ( Button = 2) All good
The train runs Loop 2 ( Button = 3) All good
The tain runs Loop 3 ( The turn outs activate ) Button = 4
The train runs Loop 4 and now is directed to the Inside loop.
The power is turned off.
Now when the power is restored Button = 1
With the Train Turnouts active before the Power OFF the program needs to activate the Button 4 to switch back the Turnouts.
I think by storing the Button state into EEprom 1 when I read EEprom 1 Button shoud read the Value stored in the EEprom 1.

Action
Run the Flowcode see Button advance to Button = 2.
Stop Flowcode
Run Flowcode ----? - Button = 1 not the value that was in EEprom.

Flowcode add to this help.

Hi Jleith,

I have just had a quick look at your chart, should your first eeprom macro be reading address 1 and not the variable value "button" ?

Thanks
Stuart

Hello Stuart

I made the changes you suggested and still eeprom will not strore the value of 'Button" used to select the selections.

It is hard to see if the value of Button is being written to the eeprom. I can see variables but not eeprom.

Here is snap shot

John,

Your read macro content is still not right, check the screen shot Stuart provided on how to set the values. Once correctly filled the flowchart icon looks like this:

To view the eeprom contents, open the eeprom1 tab in the console:

Hello Kersing
Thank you for the clarity. I could not see the "Read(1) on Sturat's image.

I have made the change and I still can't seam to have the Button saved in EEprom1

I see it listed in EEprom1 when it reaches Loop 2

Is it that when the program starts up again I have the Variables set before it reads eeprom1.

My thought is it reads the Variable ( Button = 1 ) then a few steps down there is a read of Eeprom1 and it should cahnge Button from 1 to 2.

But it looks like when the program runs eeprom1 is refresshing.

See this picture of the steps.

Take a look at the EEPROM properties, there are initialization settings in the properties.

Hi Kersing
I cleared the properties

Still not able to caputue the results of the Eeprom. It looks as if it is there but when I read it it does not put the value of eeprom1 into Button ?

Here is the next pictures
I hope the pictures capture the 1000 words.

I have placed a LCD list of Button 2 as it enters the loop.

I have aslo attatched the flowcode version 2 copy

John,

Your read macro is still wrongly configured. You need to have a macro call with:
Parameters: Address = 1. NOT Button=eeprom1::Read(1), just the number 1.
Return value: Button. Not empty like it is now.

Hello Kersing

I have it working 100% I missed the set of adding the 'Button" to the return field.

Thank you for your help. I now have a better understanding on the eeprom function.
