现想通过遥控器串口读取数据后无线发送给minifly,对遥控器的USART1写初始化程序后,遥控器界面一直在闪烁,测试几次后遥控器黑屏。
但遥控器黑屏后依旧可以连接minifly,也可以通过串口收发数据,请问有哪里出错了吗?
附上USART1初始化语句。注释初始化语句,遥控器正常工作。
void configParamInit(void)
{
if(isInit) return;
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
NVIC_InitTypeDef NVIC_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1,ENABLE);
//输入针脚配置
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9; /*U1_TX*/
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10; /*U1_RX*/
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOA, &GPIO_InitStructure);
USART_InitStructure.USART_BaudRate = 9600;
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_Init(USART1, &USART_InitStructure);
//USART1中断优先级设置
NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
NVIC_InitStructure.NVIC_IRQChannelSubPriority= 0;
NVIC_InitStructure.NVIC_IRQChannelCmd =ENABLE;
NVIC_Init(&NVIC_InitStructure);
USART_Cmd(USART1, ENABLE);
USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);
}
