软件平台:STM32CubeMX 4.22 MDK 5.23 HAL库版本:FW_F1 V1.6.0 以下是分析过程: HAL_StatusTypeDef HAL_UART_Transmit(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Size, uint32_t Timeout) { uint16_t* tmp; uint32_t tickstart = 0U; /* Check that a Tx process is not already on...
中断程序(stm32f10x_it.c)可以如下完成发送:注意所有的的串口中断需要在中断服务程序中判断中断源以分别处理。 void USART1_IRQHandler(void) { if(USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) { /* Read one byte from the receive data register */ RxBuffer1[RxCounter1++] = USART_ReceiveDa...
以上代码通过`HAL_UART_Transmit`函数发送了一个字符串 "Hello, World!",`sizeof(data)`参数表示要发送的数据长度,`HAL_MAX_DELAY`表示发送数据时不设置超时。 4. 接收数据: 接收数据也可以使用查询方式或中断方式。使用查询方式时,可以使用`HAL_UART_Receive`函数接收数据;使用中断方式时,可以使用`HAL_UART_Rec...
在轮询模式发送数据调用函数HAL_UART_Transmit() ,接收数据调用函数HAL_UART_Receive(),两者的传入参数列表,以及返回值意义相同,如下图,摘自《description-of-stm32f0-hal-and-lowlayer-drivers-stmicroelectronics》P572页。 下面演示两个函数的几种调用案例: ...

HAL_UART_Transmit 4)HAL库函数HAL_UART_Receive(在stm32f4xx_hal_uart.c中) 说明: 该函数能够通过huart串口接收Size位pData数据。 参数说明: huart :选择用来接收的UART串口 pData :指向将要存放数据的指针 Size :接收数据的大小 Timeout:超时时间 ...
