XIAO host for SSCMA-Micro sensors

What you’re building

Seeed_Arduino_SSCMA is an Arduino host library for communicating with sensors that already run Seeed’s SSCMA-Micro firmware. A sketch initializes an SSCMA client, invokes inference on the connected sensor, and reads structured performance, bounding-box, classification, or point results through the library interface. An Arduino-compatible XIAO ESP32S3 Sense can serve as the host when wired and configured for a compatible SSCMA-Micro sensor, producing serial output that reports model results. This source does not turn the XIAO’s bundled OV2640 camera into an SSCMA inference target, and it does not provide a model-training pipeline. A separate compatible SSCMA-Micro sensor or vision module, with suitable firmware and connection, is therefore required. The useful outcome is a compact host that can consume on-sensor inference results without pretending the XIAO camera itself runs the referenced examples.

Key steps

1. Confirm that the intended sensor runs SSCMA-Micro firmware and that the XIAO can use the required connection as an Arduino host.
2. Download the library and add its ZIP through Arduino IDE’s Include Library workflow.
3. Include Seeed_Arduino_SSCMA.h, create an SSCMA instance, and call begin() during setup.
4. Invoke inference in the loop and inspect perf(), boxes(), classes(), or points() only after a successful invoke call.
5. Upload the sketch and verify the sensor’s inference results through the serial monitor.
