Wave Generator

---

To generate different Analog waveforms using an AVR microcontroller it is required to interface a DAC that will convert the Digital inputs given by the microcontroller into corresponding Analog outputs and thus it generates different analog waveforms.

The DAC output is current equivalent of digital input. So to convert it into voltage a current-to-voltage converter is required. This current-to-voltage converter is built using Op-Amp LM741.

Requirements:

1. The application should have a DropDown menu to select the required waveform (Square wave, Staircase wave, Sine wave or Triangular wave)
2. Ability to send the required waveform ID, amplitude value and frequency value to the connected MCU
3. Agree on a frame that contains the previous data (ID, amplitude and frequency).

Depending on the desired signal waveform, the microcontroller will generate digital values that'll be interpreted by DAC and generate the desired waveform.

3. Each signal waveform has an amplitude and frequency.

Bonus

• Extended the code to control amplitude and frequency through the PC’s GUI.
• Generate custom signals sent from the PC’s GUI.
• Add two or more waveforms.
