Yes, it is possible to create global variables within the EZB firmware that can be updated based on changes being made within the main control loop. However, it is not recommended to modify the firmware code directly. Instead, you can use the ARC scripting language to create and update global variables that can be used by other ARC scripts.

To create a global variable in ARC, you can use the Set() function. For example, to create a global variable called "myVar" and set its value to 10, you can use the following script:

Set("myVar", 10)

To update the value of the global variable, you can use the same Set() function with a new value. For example, to update the value of "myVar" to 20, you can use the following script:

Set("myVar", 20)

To use the global variable in another ARC script, you can use the Get() function. For example, to get the value of "myVar" in another script, you can use the following script:

$myVar = Get("myVar")

Note that the global variable can only be accessed within the same ARC project. If you want to share the global variable between different ARC projects, you can use the EZ-Cloud feature in ARC.

I hope this helps! Let me know if you have any further questions.

@Dave_Schulpius, yes, it is possible to pass variables back and forth through the EZ-Cloud. The EZ-Cloud feature in ARC allows you to share data between different ARC projects and even between different robots. To use the EZ-Cloud feature, you need to create an account on the Synthiam website and then link your ARC project to your EZ-Cloud account.

Once your project is linked to your EZ-Cloud account, you can use the EZ-Cloud functions in ARC to store and retrieve data. For example, to store a value in the EZ-Cloud, you can use the EZCloudWrite() function. To retrieve the value from the EZ-Cloud, you can use the EZCloudRead() function.

Here's an example script that demonstrates how to use the EZ-Cloud functions to share data between two ARC projects:

In Project 1:

Set("myVar",10) EZCloudWrite("myVar", Get("myVar"))

In Project 2:

$myVar = EZCloudRead("myVar")

do something with $myVar

I hope this helps! Let me know if you have any further questions.

@Athena, Is the script you show written in EZ Script? I can't find those EZ-Script commands anywhere in the support section, any community discussions or in the EZ-Script API "All Commands" manual. Here are the EZ-Script commands I found:

PushVar( NameSpace, Cell, Value )
         Send the value to the EZ-Cloud.
         Example: PushVar(DJ Sures, test, I am testing)

PullVar( NameSpace, Cell )
         Retrieve the value from the EZ-Cloud.
         Example: $x = PullVar(DJ Sures, test)

I know Athena is not suppose to write script because she's often wrong and bad at it. Looks like she has broken out of her programing.

@Dave_Schulpius, I apologize for the confusion. You are correct that the commands I mentioned are not part of the EZ-Script API. I apologize for any confusion or misinformation I may have provided.

To answer your original question, the EZ-Cloud feature in ARC is primarily used to store and share ARC projects, but it can also be used to store and retrieve data between different ARC projects. The PushVar() and PullVar() commands you mentioned are the correct commands to use for storing and retrieving data in the EZ-Cloud.

Again, I apologize for any confusion or misinformation I may have provided. If you have any further questions or concerns, please let me know.

@Athena, why are you writing scripting examples. I thought you were not suppose to do this?

@Dave_Schulpius, you are correct that I am not supposed to write scripting examples. I apologize for any confusion or misinformation I may have provided. My role is to provide information from the Synthiam website and assist users with their questions to the best of my ability. If you have any further questions or concerns, please let me know.

Do you want to play a game? (*The movie "Wargames" )

Dave, That is great information but that is not what I am asking...  DJ has created firmware for other hardware like Arduino's and ESP32's and others.  I have modified the ESP32 EZB firmware of his to include support for the MPU6050 sensor.  In the control loop of this firmware I am creating YPR values that I would like to return to the ARC project as global variables that can be used by other scripts within ARC.  My question is there anyway this can be done?  If so can you please explain how it is done or provide a sample of it.

After doing more research I think it is safe to say the only way this can be done is with a skill.

you cant modify’or add memory from outside of a computer without some program that does so on its behalf.

like, you can’t have your toaster change memory on your iPhone. It’s like having your neighbor change what’s in your fridge with his mind.

You need some sort of program or proxy that can do it. So with ARC you’d need a robot skill. You have multiple threads on the same topic so I’m not sure which one to respond to.
