DDS Web + Local Controller – Arduino Due

DDS-Controller is a modular system for driving an AD9850 Direct Digital Synthesizer. It runs on an Arduino Due with an LCD Keypad Shield for local control and communicates with an ESP8266-01 module for Wi-Fi access.

The project is fully documented in docs/ and follows the architecture described in architecture_overview.md.

Features

• Local menu navigation on the LCD shield
• Remote commands over Wi-Fi (ASCII or REST)
• Configuration stored in 24LC256 EEPROM
• Cross-platform CLI and experimental GUI tools

Pin assignments and OTA usage are documented in docs/configuration/pins.md and docs/configuration/ota.md. All peripherals, except the LCD shield, must use Arduino pins 20 and above.

Directory Overview

Quick Start

Firmware

1. Open firmware/due/main.ino in the Arduino IDE and flash it to the Due.
2. Build and flash firmware/esp/main.ino to the ESP8266.

CLI example

$ python pc/cli/ddsctl.py setfreq 1000000
OK

GUI example

$ cd pc/gui
$ go run .
