通过串口接收一包数据(5字节),结果总出差,如果一个一个接收就正常,代码: 1.485初始化 void init485(void) { UCTL0 = CHAR; // 8-bit character UTCTL0 = SSEL0; // UCLK = ACLK UBR00 = 0x03; // 32k/9600 UBR10 = 0; UMCTL0 = 0x4a; ME2 |= URXE0; IE2 |= URXIE0; } 2.485中断接收一包数据 #pragma vector = UART0RX_VECTOR __interrupt void r485(void) { for(cycle = 0;cycle < 5;cycle ++) {rxbuf[cycle] = RXBUF0; } cycle = 0; }
