Msp430 Clock Speed

Recommended Posts

Hello there,



Found out the speed of my clock.

The problem now is I don't think my interrupt is working.



I am doing a project where I have to read in a square wave and determine the frequency of the wave then output that number.

I was wondering if someone could help me out by telling me what the base clock speed is.  I am programming through energia, idk if that will effect the speed at all, but just in case I am.


Hope someone can help me out


Thanks a bunch!!


if you don't know what energia is energia.nu is where you can find information


My code so far

 This example code is in the public domain.

int ledPin0 = 2;// select the pin for the LED
int ledPin1 = 3;
int ledPin2 = 4;
int ledPin3 = 5;
int ledPin4 = 6;

int sensorPin = A5;    // select the input pin for the potentiometer

int temp=0;
//int count=0;
int count1=0;
int number=5;
void setup() {
  // declare the ledPin as an OUTPUT:
  pinMode(ledPin0, OUTPUT);
  pinMode(ledPin1, OUTPUT);
  pinMode(ledPin2, OUTPUT);
  pinMode(ledPin3, OUTPUT);
  pinMode(ledPin4, OUTPUT);

void loop() { 
  //Check for Frequency
  number = 1000000/count1;
  //Make temp Variable to change
  temp = number;
  //Coverts that number to binary
  //Checks if it need to turn on light 5
  if(temp >= 16){
    digitalWrite(ledPin4, HIGH);
    temp = temp - 16;
    digitalWrite(ledPin4, LOW);
  //Checks for light 4  
  if(temp >= 8){
    digitalWrite(ledPin3, HIGH);
    temp = temp-8;
    digitalWrite(ledPin3, LOW);
   //Checks for light 3
  if(temp >= 4){
    digitalWrite(ledPin2, HIGH);
    temp = temp - 4;
    digitalWrite(ledPin2, LOW);
  //Checks for light 2  
  if(temp >= 2){
    digitalWrite(ledPin1, HIGH);    
    digitalWrite(ledPin1, LOW);
  //Checks for light 1  
  if (number%2 == 1){
   digitalWrite(ledPin0, HIGH);
  digitalWrite(ledPin0, LOW);
   count1 =0;           
//Interuppt Routine
void inter()
