各位好，我用的是stm32f103r8t6，我设成奇校验时，设置如下
switch((unsigned char)(*(DataReg+LINE_SET)>>8))
{
case 0: //无奇偶校验
USART_InitStructure.USART_Parity =USART_Parity_No; //无奇偶校验
USART_InitStructure.USART_WordLength = USART_WordLength_8b;//8位数据位
break;
case 1: //奇校验
USART_InitStructure.USART_Parity =USART_Parity_Odd;//奇校验
USART_InitStructure.USART_WordLength = USART_WordLength_9b;
break;
case 2://偶校验
USART_InitStructure.USART_Parity =USART_Parity_Even; //偶校验
USART_InitStructure.USART_WordLength = USART_WordLength_9b;
break;
default:break;
}
在PC端设为奇校验能通讯，奇怪的是设为偶校验竟然也能通讯，我在CPU设为偶校验时也一样，PC端奇偶校验都能通讯上，这是什么道理呀？ |
