A316 No-Development Firmware MCU Development Guide¶
Development Overview¶
This document provides comprehensive guidance for XU316-to-MCU communication development, helping developers implement communication functionality between XU316 and MCU in the correct sequence. The development process is divided into the following main steps, each with corresponding reference documentation and detailed instructions.
Development Steps¶
Objective: Understand the basic concepts and protocol structure of XU316-MCU communication
Reference Documentation: XU316 and MCU Communication Protocol Command Macro Definitions
Key Learning Points:
- Master the basic structure of frame format (frame header, command, data length, checksum, frame tail)
- Understand data length definitions for various commands
- Familiarize with audio format enumerations and type definitions
- Learn the composition of command data structures
Objective: Implement basic communication functions between XU316 and MCU
Reference Documentation: XU316 and MCU Communication Protocol Reference
Development Tasks:
- Implement ring buffer initialization and management
- Implement data frame encapsulation and transmission
- Implement data frame reception and parsing
- Implement CRC32 and simple checksum calculation
- Implement basic communication protocol processing flow
Objective: Configure XU316 audio interfaces and related parameters
Reference Documentation: XU316 Audio Interface Control Code Examples
Development Tasks:
- Configure I2S master/slave mode
- Set audio sampling rate and bit depth
- Configure audio channel count
- Set volume control parameters
- Configure various audio interfaces (SPDIF, ADAT, DSD, etc.)
