Week 8: Embedded Programming

This week we have to reed the datasheet of the microcontroller which we use for programming. I have choosen ATmega328p-PU for this assignement. Later we have to programm the Hello World Board.

Programm Tests with Atmega328p and Arduino IDE

 

    int buttonPin = A0;              // here I define the the pin which will become the information about the button state 
    int ledPin =  A1;                // here I define the pin which will give the information to the LED


    int buttState = 0;               // this variable should become the information about the button status


    void setup() {                   // void setup is the main program

      pinMode(ledPin, OUTPUT);       // here I tell the MCU that the LED pin will have to give some output
      pinMode(buttonPin, INPUT);     // here I tell Arduino IDE  that the button will give some input
    }

    void loop() {                     // void loop I need for contineous repating of the commands contained


      buttonState = digitalRead(buttonPin);   // read the the button(pin) state and save it into variable "buttState"


      if (buttonState == HIGH) {              // check if the button is pressed (level = high = 5V)

        digitalWrite(ledPin, HIGH);           // if button is pressed turn LED on (5V)
      } else {

        digitalWrite(ledPin, LOW);            // else if the button state is not pressed, turn LED off (0 V)
      }
    }     

    
    
    

                                 

    void setup() {                   // the setup function runs once when you press reset or power the board


        pinMode(A1, OUTPUT);         // here I define the pin which will give the information to the LED
        
        }

    void loop() {                   // void loop I need for continueous repating of the commands contained

      digitalWrite(A1, HIGH);       // turn the LED on (5V)

      delay(1000);                  // wait for one second (1000 ms) 

      digitalWrite(A1, LOW);        // now turn the LED off. to do this set the voltage LOW

      delay(5000);                  // wait for five seconds (this causes slow blinking)
    }      

        
        
        

      
    
       
    void setup() {

        pinMode(A1, OUTPUT);
    }


    void loop() {
    
      digitalWrite(A1, HIGH);   // turn the LED on (HIGH is the voltage level)

      delay(1000);                       // wait for a second

      digitalWrite(A1, LOW);    // turn the LED off by making the voltage LOW

      delay(1000);                       // wait for a second
    }
