7.11 It was stated in this chapter that the watchdog timer could be configured as an interval counter. Configure the MSP430 Watchdog Timer to toggle the red LED in the MSP430 Launchpad every three (3) seconds. To conserve energy the MSP43O needs to enter a low power mode after your configuration is complete. Solution /* We can blink the RED LED for 3 seconds with code. The basic logic I have here is, I\'ll just make the LED on and of every 250ms for 3 seconds Connect a Red LED to the Pin 2. */ // This start when push the reset button: void setup() { // Setting the output. pinMode(RED_LED, OUTPUT); } // This for loop runs for 3 seconds. i.e and LED keeps a loop of totall 250 + 250 ms = 500ms. This must loop for 500ms X 6 = 3000ms: for(i=0;i<6;i++); { digitalWrite(RED_LED, HIGH); // Light on for 250ms delay(250); // wait for a second digitalWrite(RED_LED, LOW); // Light off for 250ms delay(250); // wait for a second } // Now we introduce a program to make the MSP430 to sleep to maintain the device in low power mode: { if(i == 6) { digitalWrite(RED_LED, LOW); // turn off } .
