msp430f149 串口？ [复制链接]

我用串口调试助手调试  没动静啊


以下是程序
#include

static char string1[8];
char i;
char j = 0;

void main( void )
{
  WDTCTL = WDTPW + WDTHOLD;
  P3SEL |= 0x30;
  
  ME1 |= UTXE0 + URXE0;
  UCTL0 |= CHAR;
  UTCTL0 |= SSEL0;
  UBR00 = 0x03;
  UBR10 = 0x00;
  UMCTL0 = 0x4a;
  UCTL0 &= ~SWRST;
  IE1 |= URXIE0 + UTXIE0;
  IFG1 &= ~UTXIFG0;
  
  _BIS_SR(LPM3_bits + GIE);
}

#pragma vector = UART0TX_VECTOR
__interrupt void tx0()
{
  if(i < sizeof string1)
    TXBUF0 = string1[i++];
}

#pragma vector = UART0RX_VECTOR
__interrupt void rx0()
{
  string1[j++] = RXBUF0;
  if(j > sizeof string1 -1)
  {
    i = 0;
    j = 0;
    TXBUF0 = string1[i++];
  }
}
