STM32Hal串口发送

在STM32 HAL库中，可以使用以下函数进行串口发送：
HAL_UART_Transmit(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint32_t Timeout);
其中，huart是UART_HandleTypeDef类型的串口句柄，pData是发送数据的缓冲区指针，Size是要发送的数据长度，Timeout是发送超时时间。通过调用这个函数，可以将指定长度的数据发送到串口中。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
