大家好。 请问用STM32F101的串口1向PC机接收数据,为什么第一数据总丢啊?
比如我发送StelCom,PC接收到的是telCom。用串口监控工具发现最后一个数据变成0了。
先谢谢。
串口设置如下:USART_InitStructure.USART_BaudRate = 115200; USART_InitStructure.USART_WordLength = USART_WordLength_8b; USART_InitStructure.USART_StopBits = USART_StopBits_1; USART_InitStructure.USART_Parity = USART_Parity_No; USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None; USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx; USART_InitStructure.USART_Clock = USART_Clock_Disable; USART_InitStructure.USART_CPOL = USART_CPOL_High; USART_InitStructure.USART_CPHA = USART_CPHA_2Edge; USART_InitStructure.USART_LastBit = USART_LastBit_Disable;
