I have made this code with my group now we want to edit it and make the code read voltage of a battery but we're not sure how to edit it because the professor want it in the same form as below and by the simple C Please don't forget to put comments so I would know what you actually changed float ThresholdExceeded = 0; char x[] = " out of 3.3v \n"; volatile unsigned int i=2001; void setup() { ADC12CTL0 = ADC12SHT02 + ADC12ON; // Sampling time, ADC12 on ADC12CTL1 = ADC12SHP; // Use sampling timer ADC12IE = 0x01; // Enable interrupt ADC12CTL0 |= ADC12ENC; P6SEL |= 0x01; // P6.0 ADC option select P1DIR |= 0x01; // P1.0 output P4DIR |= 0x80; // P4.7 output Serial.begin(9600); } void loop() { ADC12CTL0 |= ADC12SC; // Start sampling/conversion __bis_SR_register(LPM0_bits + GIE); // LPM0, ADC12_ISR will force exit __no_operation(); // For debugger /* Serial.println(ThresholdExceeded); */ if(i<1000) // continuous loop { P1OUT |= BIT0; // P1.0=1 /* for(i=50000;i>0;i--); */ // Delay } else { P1OUT &= ~BIT0; } // P1.0 = 0 Serial.println(i); i=i+1; } #if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__) #pragma vector = ADC12_VECTOR __interrupt void ADC12_ISR(void) #elif defined(__GNUC__) void __attribute__ ((interrupt(ADC12_VECTOR))) ADC12_ISR (void) #else #error Compiler not supported! #endif { switch(/*__even_in_range(ADC12IV,34)*/ADC12IV) { case 0: break; // Vector 0: No interrupt case 2: break; // Vector 2: ADC overflow case 4: break; // Vector 4: ADC timing overflow case 6: // Vector 6: ADC12IFG0 if (ADC12MEM0 >= 0xFA0) // ADC12MEM = A0 > 0.5AVcc? {i=0;} /* {P4OUT &= ~BIT7; // P4.7 = 0 P1OUT &= ~BIT0; } // P1.0 = 0 /* else if (ADC12MEM0 <= 0x6d6) {P4OUT &= ~BIT7; // P4.7 = 0 P1OUT |= BIT0; } // P1.0 = 1 else if (ADC12MEM0 <= 0x794) {P4OUT |= BIT7; // P4.7 = 0 P1OUT |= BIT0; } /*else {P4OUT &= ~BIT7; // P4.7 = 1 P1OUT &= ~BIT0; } // P1.0 = 1 */ __bic_SR_register_on_exit(LPM0_bits); // Exit active CPU case 8: break; // Vector 8: ADC12IFG1 case 10: break; // Vector 10: ADC12IFG2 case 12: break; // Vector 12: ADC12IFG3 case 14: break; // Vector 14: ADC12IFG4 case 16: break; // Vector 16: ADC12IFG5 case 18: break; // Vector 18: ADC12IFG6 case 20: break; // Vector 20: ADC12IFG7 case 22: break; // Vector 22: ADC12IFG8 case 24: break; // Vector 24: ADC12IFG9 case 26: break; // Vector 26: ADC12IFG10 case 28: break; // Vector 28: ADC12IFG11 case 30: break; // Vector 30: ADC12IFG12 case 32: break; // Vector 32: ADC12IFG13 case 34: break; // Vector 34: ADC12IFG14 default: break; } ThresholdExceeded = ADC12MEM0; }
