The document outlines a C program for the MSP430G2553 microcontroller to display a scrolling message, 'Esteban Montanez', using two seven-segment LED devices. It includes code to blink a red LED connected to P1.0 while setting up output for the LEDs and creating a delay. The program continuously toggles the state of the red LED in an infinite loop.

- 1. Write an MSP430g2553 C program to drive a continually scrolling message with the following text: Esteban Montanez Use two seven segment LED segment devices to show the text (two characters at a time) at a reasonable reading rate. Solution //to blink the red LED (LED1) on the TI Launchpad //which is attached to P1.0 //The green LED(LED2) is connected to P1.6 #include int main(void) { volatile int i; // stop watchdog timer WDTCTL = WDTPW | WDTHOLD; // set up bit 0 of P1 as output P1DIR = 0x01; // intialize bit 0 of P1 to 0 P1OUT = 0x00; // loop forever for (;;) { // toggle bit 0 of P1 P1OUT ^= 0x01; // delay for a while for (i = 0; i < 0x6000; i++); } }
