关于战舰开发板LCD例程中USART发送完毕中断问题

shurongcheung · 发表于 2015-3-12 22:13:39

在战舰开发板的LCD例程中，如果在USART初始化时候开启发送中断就会卡死，有谁遇见过这样的情况
添加红色语句LCD就无法点亮，如何解决？谢谢
#if EN_USART1_RX
NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority=3 ;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);

USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);
USART_ITConfig(USART1, USART_IT_TC, ENABLE);
#endif
USART_Cmd(USART1, ENABLE);
