Write component property to sd-card

Post by stefan.erni »

Hi Ben

I would like to write the component propertis at the beginning of the Excel file.
Append string works with a text, but not with the build in function created string.
Does it work the way I program it?

Hello,

Hmm this one is a little tricky as you can't directly reference component properties.

One trick would be to do the following.

1) Click on a blank area of the panel to select the panel and in the properties window create properties to hold the values
2) Add a macro to the Compile Start event and to the Simulation Start event, this can be the same macro for both events
3) Inside the Compiler Start macro copy the value of the property you want to your local property
4) Reference the local properties in your program as you would variables

That should work.

I've included an example.

Hi Ben

I have tried but I probably only get the index of the switch and not the text of the property

Hello,

GetValue returns the property value, if instead you want the label string then use the GetListItem function to get the label assigned to the value.

Hi Ben

Yes this way is perfect.
Unfortunately working only in the simulation. I cannot compile to hex. There is a fail.

Hello,

Compiling now. Could be the sim event macro is missing a return value and the ESP32 compiler is complaining about that.

Just add a calculation saying .Return = 1
