HAL_UART_Transmit(&huart1, (uint8_t *)&ch, 1, 0xFFFF);这个语句表示通过串口1发个一个字符。ch为字符的存储地址,0xFFFF为超时时间。在stm32f7xx_hal_uart.c文件中可以找到HAL_UART_Transmit函数。 在main.c文件中添加应用函数。 /*USERCODEBEGIN2*/printf("\n\rUART Printf Example: retarget the ...

HAL_UART_Receive_IT(&huart2,(uint8_t *)&value,1);//程序不会在这个语句停留,直接会按照中断方式把接收数据存放在value中,但是这个语句只能使能一次串口中断。所以要在中断服务函数或者回调函数中重新使能 串口接收功能3: if(HAL_UART_Receive_IT(&huart2,(uint8_t *)&value,1) != HAL_OK){ //这...
USART/UART pins can be remapped usingAFIO_MAPRregister. By default, the default pins like PA9 and PA10 for USART1 are used and not remapped elsewhere because this register is by default cleared and hardware remapping is not enabled. ...
