Sequence and procedures

Program sequence
The basic program flow is described in the following:
1. The MicroPython script is copied to the SIMATIC Memory Card that is inserted in the
TM NPU.
2. During initialization, the TM NPU checks if the MicroPython script "main.py" is present on
the inserted SIMATIC Memory Card.
3. The "main.py" script is loaded into the RAM of the TM NPU.
4. The required initializations are executed by the "main.py" script:
– Instantiation of the camera and video pipeline
– Loading of the neural network
5. Additional module functionality is defined, e.g.:
– Waiting for trigger condition from the CPU
– Fetching an image from the camera stream
– Pre-processing the image via video pipeline
– Processing of the pre-processed image via neural network
