RDK X5 Application Case Guide

This document collects typical application cases for the RDK X5 platform. It is organized by increasing difficulty, from basic peripheral interfaces to on-device AI inference, then to interactive games and a multimodal chatbot, so you can get started quickly and go deeper step by step.

Document Structure​

Getting Started Cases​

These cases introduce how to connect and use common onboard peripheral interfaces. Interface numbers use BOARD numbering.

  • GPIO: Capture button press events
  • PWM: Servo angle control
  • UART: UART loopback test
  • I2C: OLED display
  • SPI: SPI screen animation / image display
  • Earphone Audio Jack: Recording and playback
  • USB: USB camera capture
  • CAN: GM6020 motor control

Basic Cases​

These cases deploy entry-level AI models on RDK X5, covering typical vision detection and speech scenarios.

  • Detect: YOLO11m object detection (image / camera)
  • ASR: SenseVoice speech-to-text
  • KWS: Keyword spotting (你好地瓜)
  • TTS: Matcha text-to-speech

Intermediate Cases​

  • Gesture Interaction Game: Body detection + hand landmarks + gesture recognition, with a browser-based interactive experience on TROS.

Advanced Cases​

  • Chatbot: Multimodal voice dialogue with KWS + ASR + LLM + TTS
