Hi

I am new to CCS, and I am having trouble in configuration/ initialization of UART. I referred slau445g for initiating the registers.

My primary aim is to transmit a single byte/ buffer(if possible) to comp port, attaching code for persual. Any help would be really appriciated.

//#include <classic.h>
#include <msp430.h>
#define DELAY 10000

unsigned int txint=12;

void txdata(unsigned int txint){

//UCA0IFG |= 0x02;
//while(UCA0TXIFG)
UCA0TXBUF = 0x01;
}

void init_uart(void){
P1SEL0 |=(BIT0 |BIT1);

UCA0CTLW0 |= UCSWRST;

UCA0CTLW0 |= UCSSEL__SMCLK;

UCA0BR0 = 104; // 16000000/16*9600

UCBRSx=0x49;

UCA0BR1 = 0x00;

UCA0MCTLW = UCOS16 | UCBRF_1;

UCA0CTLW0 &= ~UCSWRST;

UCA0IE |= UCRXIE;

RTCCTL &= ~RTCIE;
}

void init_delay(int l){
int i;
for(i=0;i>l;i++);
}

int main(void) {
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer

init_uart();

while(1)
{
txdata(txint);
init_delay(DELAY);
}

}

Thank you
