Question

Using an MSP430 modify the source code provided to complete the following:

A. Write a function named sec_hundredths_delay() that will take one argument that specifies a delay in hundredths of a second. B. Modify your software to continually read a user-input five-bit number to be used as time in hundredths of a second to turn on the output LED calling sec_hundredths_delay(). Every time the LED is on, it must then go off for 200 ms. C. Test your implementation turning on the LED for 50 ms, 500 ms, and 3 seconds.

Explanation / Answer

a.

c.

void setup() {

   pinMode(50ms, OUTPUT);

   pinMode(500ms, OUTPUT);

pinMode(3000ms, OUTPUT);

}

void loop() {

   digitalWrite(50ms, HIGH);   

   for (int x=0; x < 1000; x++) {   

      delay(1);

   }

   digitalWrite(500ms, HIGH);

   for (int x=0; x < 1000; x++)

{

      delay(1);

   }

digitalWrite(3000ms, HIGH);

   for (int x=0; x < 3000; x++)

{

      delay(1);

}
