Introduction

This example demonstrates the Device Agent Protocol (DAP) communication layer used for integration with Edge AI Studio. DAP provides a standardized UART-based protocol for streaming sensor data, receiving commands, and transmitting inference results between the microcontroller and Edge AI Studio.

This example serves as a reference implementation for:

Establishing DAP communication with Edge AI Studio
Implementing sensor data streaming
Handling pipeline configuration commands
Transmitting inference results

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am261x-lp
Example folder	examples/ai/dap_default/

DAP Protocol Overview

The Device Agent Protocol (DAP) provides:

Frame-based communication: CRC-validated frames for reliable data transfer
Multiple data channels: Support for sensor signals, inference signals, results, values, and logs
Command handling: Pipeline configuration and control commands from Edge AI Studio
Multi-sensor streaming: Support for streaming data from multiple sensors simultaneously

Key DAP Functions

Function	Description
`Dap_Init()`	Initialize DAP instance
`Dap_Process()`	Main processing loop
`Dap_SendSensorData()`	Stream sensor data
`Dap_StartSensorStream()`	Start sensor streaming
`Dap_StopSensorStream()`	Stop sensor streaming

Dependencies

Edge AI Studio for communication
UART interface for DAP protocol

Steps to Run the Example

When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
Connect Edge AI Studio to the device via UART
