Topic: How to create SFX without a diagram and even a firmware?

Hello

I need to be able to create an SFX to allow users to update the User Parameters BUT I do not want to provide the diagram as it could be stolen to replicate the modules. The firmware is not even needed in this use case.

Thank for any help!

Re: How to create SFX without a diagram and even a firmware?

For now, the User Parameters is a part of the diagram. You can't make the SFX with the User Parameters but without a diagram.

However, you can implement the some sort of receiving a simple "parameters" in your diagram during it operation and save them into EEPROM.

In this case, parameters data input can be organized using a discrete button on CANNY inputs, CAN or UART messages.

Returning to SFX:

An SFX does not contain a diagram, but its binary code. Hacking SFX will require some effort. For that matter, even microchips are hackable.

Each device instance has a unique 32 bit ID.

You can link your diagram to a specific device ID.

Hello

Ok, thanks for your valuable inputs. You anyway want to think about this use case in a future version of the "Create SFX" function.

This being said, I am not sure what will be the future of this as I think we cannot buy anything from Russia anymore considering the situation.

Sure, we will think about such SFX function. Thank you for your advice!

And you can buy anything from Russia, but with slightly increased logistics costs.

So it makes sense to buy a significant amount of devices at once.

Hello

If I want to use the Device Ids. Is there a way to have the determination it is a valid device (as you documented) calculated once at the beginning only then for future loops it is no more executed to avoid spending resources for nothing?

Maybe this way will work for you (see attachment)

Thank you!
That should work.
How can I simulate this?
How long the reset condition is valid? 1 cycle?

You can force values in simulator: https://cannylogic.com/docs/cannylab/si … ced_values
