sku (char[16]): SKU of the product.
name (char[64]): Name of the product.
price (int32_t): Price of the product in cents.

Struct: PredictOutput#

Represents the output of a prediction.
products (Product[16]): Array of up to 16 product information.
products_size (int32_t): Number of products recognized in the current prediction.
has_prediction (bool): Indicates whether there is a prediction result (there may be AI recognition but no corresponding product).

Function: start_service#

Starts the service.
assets_root (const char*): Path to the resource storage.
version (const char*): Version number of the software (if unknown, use "Unknown").
Returns: int32_t status code.

p_1_x to p_4_y (int32_t): X and Y coordinates of the four points (range: [0, 100]).
Returns: int32_t status code.

Function: product_import#

Imports products using a CSV format list.
clear (bool): Whether to perform a full import (clears products not in the list).
data (const char*): CSV formatted product list.
Returns: int32_t status code.

Function: product_import_path#

Imports products from a file path.
clear (bool): Whether to perform a full import (clears products not in the list).
path (const char*): Absolute path to the file.
Returns: int32_t status code.

Function: clear_product#

Clears the product table.
