Flashing the device with pipeline

martin181818

Hi all,
depthai-experiments/oak.py at master · luxonis/depthai-experiments (github.com)
In this project, can you please explain the use of script node and why only half of the code is created in the script node?
The bootloader will flash the code to the device to run in stand-alone, in this case which part of the code will be flashed ( all of the code before bootloader or only the code in the script node) ?

Thank you very much

Hi martin181818

The only thing that gets flashed to the device is the pipeline (meaning all nodes along with their links and configurations) - in this case that is everything above the bootloader code. When running scripts in normal mode (using usb or eth) the pipeline is executed on the device by: with depthai.Device(pipeline) as device:. In standalone mode this is automatically called when the device boots up.

Since we can't run the code in a loop like we normally do, we port everything to the script node. Inside the script we also create a socket that is able to send data to the hosts on the other side of the socket.

Hope this helps,
Jaka
