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.
