Question
Can you help me to find the error on my code please
is for micro procesador msp430
is to control a bdc 7-segment
#include "msp430g2231.h"
int a = BIT0; //P1_0 -> Segment A
int b = BIT1; //P1_1 -> Segment B
int c = BIT2; //P1_2 -> Segment C
int d = BIT3; //P1_3 -> Segment D
int e = BIT4; //P1_4 -> Segment E
int f = BIT5; //P1_5 -> Segment F
int g = BIT6; //P1_6 -> Segment G
void delay(void);
void main(void)
{
unsigned int timeperiod; //Will be used to change timing on digits
P1DIR |= a; // Set P1.0 to output direction
P1DIR |= b; // Set P1.1 to output direction
P1DIR |= c; // Set P1.2 to output direction
P1DIR |= d; // Set P1.3 to output direction
P1DIR |= e; // Set P1.4 to output direction
P1DIR |= f; // Set P1.5 to output direction
P1DIR |= g; // Set P1.6 to output direction
P1OUT = 0x0000; //All segments OFF
while(1)
{
P1OUT &= ~(a + b + c + d + e + f + g); //Makes sure all segments are off
switch(Val)
{
case(0): //Num-0
P1OUT |= a + b + c + d + e + f;
P1OUT &= ~(a + b + c + d + e + f);
break;
case(1): //Num-1

break;
case(2): //Num-2

}
P2OUT |= BIT0; //Set P2_0-> Buzzer ON
