Electrical Engineering

write a program for the msp430fr6989

Using the general purpose timer, specifically the ACLK, create aprogram which makes LED1 stay on for 4 seconds and off for 2seconds and repeat indefinitely.

Modify the above program to extend the timing to 20 and 10seconds, respectively.

void setup() {

pinMode(led1, OUTPUT); // initialize digital pin led1 as an output.

int counter=0;

}

void loop()

{

  digitalWrite(led1, HIGH);   // turn the led1 on (HIGH is the voltage level)

  delay(4000);              // led1 stay on for 4seconds=4000 milliseconds

  digitalWrite(led1, LOW);    // turn the led1 off by making the voltage LOW

  delay(2000);              // led1 stay off for 2 seconds=2000 milliseconds

counter++; // this statement makes the program indefinetely repeat itself

}

Now program for 20 seconds ON and 10 seconds OFF is shown below

void setup()

{   

pinMode(led1, OUTPUT);

int counter=0;

}

void loop()

{

digitalWrite(led1, HIGH);

delay(20000); // 20 seconds = 20000 milliseconds

digitalWrite(led1, LOW);

delay(10000); // 10seconds =10000 milliseconds

counter++;

}
