stm32f407的drv_usart.c文件编译错误怎么解决？

172 STM32F407

问答对人有帮助，内容完整，我也想知道答案 0 STM32f407的drv_usart.c文件编译错误 static rt_err_t stm32_configure(struct rt_serial_device serial, struct serial_configure cfg) { struct stm32_uart uart; RT_ASSERT(serial != RT_NULL); RT_ASSERT(cfg != RT_NULL); uart = rt_container_of(serial, struct stm32_uart, serial); / uart clock enable / stm32_uart_clk_enable(uart->config); / uart gpio clock enable and gpio pin init */ stm32_gpio_configure(uart->config); uart->handle.Instance = uart->config->Instance; uart->handle.Init.BaudRate = cfg->baud_rate; uart->handle.Init.Mode = UART_MODE_TX_RX; uart->handle.Init.OverSampling = UART_OVERSAMPLING_16; switch (cfg->flowcontrol) { case RT_SERIAL_FLOWCONTROL_NONE: uart->handle.Init.HwFlowCtl = UART_HWCONTROL_NONE; break; case RT_SERIAL_FLOWCONTROL_CTSRTS: uart->handle.Init.HwFlowCtl = UART_HWCONTROL_RTS_CTS; break; default: uart->handle.Init.HwFlowCtl = UART_HWCONTROL_NONE; break; } switch (cfg->data_bits) { case DATA_BITS_8: if (cfg->parity == PARITY_ODD \|\| cfg->parity == PARITY_EVEN) uart->handle.Init.WordLength = UART_WORDLENGTH_9B; else uart->handle.Init.WordLength = UART_WORDLENGTH_8B; break; case DATA_BITS_9: uart->handle.Init.WordLength = UART_WORDLENGTH_9B; break; default: uart->handle.Init.WordLength = UART_WORDLENGTH_8B; break; } switch (cfg->stop_bits) { case STOP_BITS_1: uart->handle.Init.StopBits = UART_STOPBITS_1; break; case STOP_BITS_2: uart->handle.Init.StopBits = UART_STOPBITS_2; break; default: uart->handle.Init.StopBits = UART_STOPBITS_1; break; } switch (cfg->parity) { case PARITY_NONE: uart->handle.Init.Parity = UART_PARITY_NONE; break; case PARITY_ODD: uart->handle.Init.Parity = UART_PARITY_ODD; break; case PARITY_EVEN: uart->handle.Init.Parity = UART_PARITY_EVEN; break; default: uart->handle.Init.Parity = UART_PARITY_NONE; break; } #ifdef RT_SERIAL_USING_DMA uart->dma_rx.last_index = 0; #endif if (HAL_UART_Init(&uart->handle) != HAL_OK) { return -RT_ERROR; } return RT_EOK; } 中的有一段关于流控的存在问题，会造成编译不通过,struct serial_configure结构体中不存在成员变量flowcontrol，代码如下： switch (cfg->flowcontrol) { case RT_SERIAL_FLOWCONTROL_NONE: uart->handle.Init.HwFlowCtl = UART_HWCONTROL_NONE; break; case RT_SERIAL_FLOWCONTROL_CTSRTS: uart->handle.Init.HwFlowCtl = UART_HWCONTROL_RTS_CTS; break; default: uart->handle.Init.HwFlowCtl = UART_HWCONTROL_NONE; break; } 初步推测是配置工具的问题，但是在stm32h753却没有出现这种问题，。 0 本主题由 Harmony技术专家于 2024-7-25 15:53 审核通过
