AVR DDS signal generator V2.0 is a firmware based DDS signal generator which uses slightly modified Jesper’s DDS algorithm adapted to AVR-GCC C program as in-line ASM.
Main AVR DDS signal generator V2.0 features:
- Simple circuit with easily accessible and cheap components;
- Single sided PCB;
- In box power supply with external AC plug;
- Dedicated high speed (HS) signal output up to 8MHz;
- DDS signal with variable amplitude and offset;
- DDS signals: sine, square, saw, rev saw, triangle, ECG and noise.
- 2×16 LCD menu;
- Intuitive 5 button keypad.
- Frequency adjusting steps: 1, 10, 100, 1000, 10000Hz;
- Restoring last configuration after power up.
