Project description

Pi Pico Fire alarm sound detector running on W5100S Pico EVB Integrating audio machine learning on Arduino platforms running Pico Mbed OS presents significant challenges, primarily due to the reliance on external audio libraries such as CMSIS-DSP, and TensorFlow Lite for Microcontrollers (TFLM). These libraries, while powerful, introduce complexities in compatibility and resource management, as they are not natively aligned with Arduino’s lightweight abstraction layers or the constrained runtime environment of Mbed OS. The integrated platform offers a powerful advantage by seamlessly…
