AVR - Programming hardwareregisters for an Arduinoboard

This repository contains five different branches, each focusing on specific tasks related to programming AVR hardware registers for Arduinoboards.

Branches and Tasks

1. Deluppgift01-Timer1 (Timer)

Instructions:

  • Configure TIMER1 to blink an LED with 200 ms on/off cycles.
  • Use GPIO code to control an LED connected to Arduino/Freenove pin 3.
  • Utilize timer compare A interrupt to toggle the LED.

2. Deluppgift02-ADCread (ADC from Potentiometer)

Instructions:

  • Connect a potentiometer as a voltage divider to pin A0.
  • Set up ADC and read the value via hardware registers.
  • Print the read value and calculated voltage on pin A0 every second via the serial port.

3. Deluppgift03-LEDcmd (LED Control from Command Line)

Instructions:

  • Connect an LED to pin 3 (PWM capable).
  • Implement a configurable timer with Timer1.
  • Create a command interpreter that handles the command ledpower <power> <time>.

4. Deluppgift04-ButtonCounter (Using Counter Mode with Timer1)

Instructions:

  • Write a counter for the number of button presses.
  • Use Timer1 to measure the input from pin 5.
  • Print the number of button presses every second.

5. Deluppgift05-RampLED (Control PWM up and down)

Instructions:

  • Ramp an LED's power linearly from 0-255 and then down periodically.
  • Control the ramp time via a command sent through the serial port, e.g., ledramptime 500 milliseconds.

Main

  • Mainbranch is currently synced with "Deluppgift03-LEDcmd" and does not represent the full scale of the project.
  • Please select different branches for different parts of the project.

How to Use Each Branch

  1. Clone the Repository

    git clone <repository_url>

  2. Open Project in VS Code

    • Navigate to the project directory in your terminal.
    • Run code . to open the project in Visual Studio Code.

  3. PlatformIO Extension

    • Make sure you have the PlatformIO extension installed in VS Code.
    • In the PlatformIO toolbar at the bottom, select the correct board.
    • Click on the "Upload" button (arrow icon) to build and upload the code to the board.

  4. View Serial Monitor Output

    • Open the Serial Monitor by clicking on the plug icon in the PlatformIO toolbar at the bottom to view the program output.
