Implementing Interrupt & Timers Driver

Implementing ADC & UART Driver

Lab 1

Build an AVR-based system to control the speed of a DC motor using PWM signal. The system will have 2 buttons to control the motor speed up or down.

Lab 3 (GUI)

Build a GUI-based PC application that controls the serial/USB port communicating with an AVR MCU. The application should have means to select the required task from the communication (where available tasks are: 1. Read. 2. Write).

The user should have a textbox to write the address to read/write from/to.

• It should have either a textbox for the user to write data (if the writing task was selected) or a label to display the incoming read data (read task was selected). Add an LED to the AVR MCU to blink twice on any data reception or data request as an indicator.

Implementing DIO Driver

Smart Home (Web Application)

Smart home project essential software implementation for the web application (GUI and back-end).

Lab 3 (Code)

Implementation of the UART Driver for the specified GUI's target mentioned in this issue #7 ... additionally

- [ ] Extended the system to read RAM and ROM addresses.
- [ ] Add Upload new firmware using the PC functionality. Note: To achieve this task you need to execute the code in bootloader mode

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.
