Developer Information

For complete technical specifications including hardware components, schematics, and detailed architecture, see Technical Specifications.

Development Environment

Required Tools

• IDE: MCUXpresso IDE v11.8.0 or later
• Debug Probe: PEMicro USB Multilink Universal (USB-ML-UNIVERSAL)
  • Alternative: USB-ML-UNIVERSAL-FX (faster but more expensive)
• Toolchain: ARM GCC (included with MCUXpresso)

Getting Started

1. Install MCUXpresso IDE
2. Import the EQ Wave project
3. Connect debug probe to Tag-Connect interface
4. Build and flash firmware

Code Organization

• src/ - Main application code
• drivers/ - Hardware drivers (ADE9430, DP83848, etc.)
• freertos/ - FreeRTOS kernel and configuration
• lwip/ - TCP/IP stack
• config/ - Board and application configuration

Debug Configuration

• SWD interface via Tag-Connect
• Debug features available through conditional compilation
• Note: Full debug mode may impact real-time performance

Firmware Development Notes

Current Limitations

• Small CPOW buffer (< 10 ms) due to MCU RAM constraints
• Debug features introduce latency affecting concurrent data acquisition
• Random number generation needs improvement

Network Services

• Port 1535: Power monitor metrics (pmon)
• Port 1534: Continuous point-on-wave data (pwave)

Future Development

• Modbus TCP server implementation
• MQTT publisher for cloud integration
• PTP support for precision time synchronization
• GNSS timestamp integration
• Zenoh server for edge computing
• Runtime query engine (patent pending)
• Over-the-network firmware updates
• EEPROM-based configuration storage
