Hi I write a code. But it didnt work. Led is burning and burning out not with range. Where is the problem #include "msp430g2452.h" #define tr BIT0 #define ec BIT1 #define led BIT6 int range=0; void main( void ) { WDTCTL = WDTPW + WDTHOLD; //watchdog stop DCOCTL=CALDCO_1MHZ; //frequency setup BCSCTL1=CALBC1_1MHZ; P1DIR = tr+led; P1OUT=0x00; //all are zero for(; { P1OUT^=tr; //Trigger is on for 10 us __delay_cycles(10); P1OUT^=tr; if(P1IN&ec) { range++; //when echo coming range is increasing } if(range>50) { P1OUT=led; range=0; } __delay_cycles(1000000); //waiting some P1OUT^=led; } }
