Code Composer Studio Version: 6.1.2.00015 I am trying to make a very simple code but I don't know why the #29 error pops out. It's on the same line repeated, the ones in grey. The idea of the project is that using PuTTY terminal or any other terminal, I would be able to make one of the leds blink and control the brightness of the other led and when I write 'EF' in the terminal, the MSP430G2553 should return a status message. //****************************************************************** // USCI UART //****************************************************************** #include " msp430g2553 .h" #define PER 50000 #define COUNT 10 //****************************************************************** // Global data //****************************************************************** const char string1[25]; int counter=COUNT; unsigned int i; unsigned int blink=0; unsigned int recieved=0; unsigned int brightness; //****************************************************************** // Function prototypes //****************************************************************** void UARTSetup(void); //***************************************************************** // Main routine //***************************************************************** void main(void) { WDTCTL = WDTPW | WDTHOLD; // Stop WDT //--------------------- Ports ----------------------------- P1DIR |= 0x41; //P1.0 and P1.6 as digital outputs - LED1 and LED2 P1DIR &= ~0x08; //P1.3 as input - SW1 P1SEL = BIT1 | BIT2 | BIT6; // P1.1 = RXD, P1.2=TXD P1SEL2 = BIT1 | BIT2 ; // P1.1 = RXD, P1.2=TXD P1REN |= 0x08; //Enable PULL UP/DOWN resistor P1OUT |= 0x08; //PULL UP resistor set //--------------------- Basic Clock ----------------------------- if (CALBC1_1MHZ ==0xFF || CALDCO_1MHZ == 0xFF) { while(1); // If calibration constants erased // do not load, trap CPU!! } //1Mhz BCSCTL1 = CALBC1_1MHZ; // Set range DCOCTL = CALDCO_1MHZ; // Set DCO step + modulation */ //LFXTAL BCSCTL1 |= DIVA_0; BCSCTL2 = SELM_2 | DIVM_0; BCSCTL3 = LFXT1S_0 | XCAP_1; //blinking initial configuration P1DIR |= 0x09;//xxxx 1xx1 P1DIR &= ~0x08;//xxxx 0xx1 P1REN |= 0x08; P1OUT |= 0x08; P1OUT &= ~0x09; P1OUT |= 0x08; P1IFG = 0x00; P1IES |= 0x08; P1IE |= 0x08; //--------------------- Timer A ----------------------------- TA0CTL = TASSEL_2 |MC_1 | ID_0 ; // SMCLK, up mode CCTL0 = CCIE; // CCR0 interrupt enabled CCR0 = PER; CCTL1 = OUTMOD_6; // CCR1 int. enabled CCR1 = 25000;//HIGH_STATE_INI; //--------------------- USCI ------------------------------------ UARTSetup(); __bis_SR_register(LPM1_bits + GIE); // Enter LPM3 w/ int until Byte RXed } //****************************************************************** // Interrupt service routine: //****************************************************************** #pragma vector=TIMER0_A0_VECTOR __interrupt void Timer_A_CC0 (void) { if(blink==1){ counter--; if(counter == 0) {// && counter1==0){ P1OUT ^= 0x01; // overflow counter=COUNT; } } } #pragma vector=USCIAB0TX_VECTOR __interrupt void USCI0TX_ISR(void) { UCA0TXBUF = string1[i++]; // TX next character if (i == sizeof string1 - 1){ // TX over?
