EdgeImpulse_FOMO_NO_PSRAM.ino

/**
 * Run Edge Impulse FOMO model.
 * It works on both PSRAM and non-PSRAM boards.
 * 
 * The difference from the PSRAM version
 * is that this sketch only runs on 96x96 frames,
 * while PSRAM version runs on higher resolutions too.
 * 
 * The PSRAM version can be found in my
 * "ESP32S3 Camera Mastery" course
 * at https://dub.sh/ufsDj93
 *
 * BE SURE TO SET "TOOLS > CORE DEBUG LEVEL = INFO"
 * to turn on debug messages
