Run program on SD card

Projects General Guidance

Hello,

Is that possible to compile the program on SD card and run from that ? or SD card is only used for logging and reading data ?

You can't run program directly from an SD card. It should be loaded to controller memory first.

Depends on which Arduino you are talking about. The Yun could do this

Even Yun can not execute program directly from SD. It just has some embedded mechanism to load program from SD to internal memory.

However, you could write an interpreter do perform the specific hardware functions you need, then use a script file (§usually plain text) to feed that interpreter.
You can change scripts any time, and restart.

Yes it is called a operating system - Linux in the case of the Yun.

Not being able to use an SD card was true back in the days when there was just the Yun.
