LPC2366串口0和串口1通信,求高手请教,单个字节可以实现,多个字节就有问题
本人是新手,在编写LPC2366的串口通信时,串口0和串口1之间的通信,单个字节的时候可以实现,但传输字符串的时候就出问题,请高手请教,这是我的部分程序:void __irq IRQ_UART1(void)
{
if((U1IIR&0x0F)==0x04)
{
rcv1_new = 1; // 设置接收到新的数据标志,并清除中断标志位
zifu1=U1RBR;
}
VICVectAddr = 0x00;
}
void UART1_Init()
{
unsignedlong Fdiv;
PINSEL0 |= (0x01<<30) ; /* RxD1 and TxD1 */
PINSEL1 |=0x01 ;
U1LCR = 0x83; /* 8 bits, no Parity, 1 Stop bit */
Fdiv = ( Fpclk / 16 ) / UART_bps ; /*baud rate */
U1DLM = Fdiv / 256;
U1DLL = Fdiv % 256;
U1LCR = 0x03; /* DLAB = 0 */
U1FCR = 0x07; /* Enable and reset TX and RX FIFO. */
VICIntEnClr = 1 << 7; /* Disable Interrupt */
VICVectAddr7= (unsigned int)(void *)IRQ_UART1;
VICVectPriority7=0;
VICIntEnable = 1 << 7; /* Enable Interrupt */
U1IER = 0x01|0x02 ; /* Enable UART1 interrupt */
}
while(1)
{
for(j=0;j<10;j++)
{
UART1_SendByte(send_buffer);
if( rcv1_new==1)
{
rcv1_new = 0;
UART0_SendByte(zifu1);
}
}
