Part Number: MSP432P401R
Tool/software: Code Composer Studio
For context I am taking the last 3 digits of someones ID# and then using that as a way to control the delay time of the onboard LED's blinking where I am having issues with the __delay_cycles(); function with it saying that it expected an integer constant even though I am supplying it an integer where not even making my integer name Red_light a const int seems to fix the issue, what suggestions would you give me as a way of fixing this problem?
#include "msp.h"
void main(void)
{
WDT_A->CTL = WDT_A_CTL_PW | WDT_A_CTL_HOLD; // stop watchdog timer
char ID[2];
printf("Please enter in the last 3 digits of your school ID \n"); //this part of the code has the user enter in a number as a string of characters
scanf("%s", &ID); //that will then be converting to integers down below
int n1 = ID[0] - '0'; //These three lines succusfully convert the char's back into int's just follow the
int n2 = ID[1] - '0'; // int n1 = some number - '0' formula;
int n3 = ID[2] - '0';
const int Red_light = (n1 * 10) * 1000; //constant integer values meant to go inside of the
const int Green_light = (n2 * 10) * 1000;// __delay_cycles() function;
const int Blue_light = (n3 * 10) * 1000;
while(1){
P1DIR = P1DIR | 0x09; //P2.0 to logic one
__delay_cycles(Red_light);//Delay before turning off
P1DIR = 0x00;
P2DIR = P2DIR | 0x02;//GREEN light
P2OUT &= 0xFE; //P2.0 to logic zero
P2OUT |= 0x02; //P2.1 to logic one
P2OUT &= 0xFB; //P2.2 to logic zero
__delay_cycles(Green_light);//Delay
P2DIR |= 0x04; //BLUE
P2OUT &= 0xFE; //P2.0 to logic zero //BLUE light
P2OUT &= 0xFD; //P2.1 to logic zero
P2OUT |= 0x04; //P2.2 to logic one
__delay_cycles(Blue_light);//Delay before turning off
P2DIR = 0x00;
}
}
