刚搞了个VS1053模块，就试着弄弄正弦测试成功了，但是读寄存器总是不对uint8 RxFlag=0;
uint8 RX_DATA[2];void SPI_Init()
{
  U0CTL = CHAR + SYNC + MM + SWRST;                     // 8-bit, SPI, master
  U0TCTL = SSEL1 + SSEL0 + STC;                          // Polarity, 3-wire
  U0TCTL&=~CKPL;
  U0BR0 = 0x02;                                 // SPICLK = SMCLK/2
  U0BR1 = 0x00;
  U0MCTL = 0x00;
  ME1 |= USPIE0;                                // Module enable
  U0CTL &= ~SWRST;                              // SPI enable
  IE1|=URXIE0;
  P3SEL |= 0x0E;                            // P3.1,2,3 SPI option select
  P3DIR |= 0x0A;                           
}uint16 SPI_Read()                       //read from spi port 
{
    uint16 temp;
    while(RxFlag!=2);
    RxFlag=0;
    temp=RX_DATA[0];
    temp<<=8;
    temp|=RX_DATA[1];  
    return temp;
} #pragma vector=USART0RX_VECTOR
__interrupt void UartRx()
{
    RX_DATA[RxFlag++]=RXBUF0;
}总是返回的全是0求助啊  [ 本帖最后由 yangyifeng01 于 2012-3-11 12:15 编辑 ] 此帖出自小平头技术问答
