OSDK STM32 platform UART port change

Keywords: OSDK STM32 platform, UART port

On the OSDK STM32 platform, the default UART port connected to the drone is USART3. how to change this UART port?

Just change the callback registered in the OSDK to the UART port used.

static T_OsdkHalUartHandler halUartHandler;
halUartHandler.UartInit = OsdkSTM32_UartInit;
halUartHandler.UartWriteData = OsdkSTM32_UartSendData;
halUartHandler.UartReadData = OsdkSTM32_UartReadData;
halUartHandler.UartClose = OsdkSTM32_UartClose;

Or directly modify the code in the UART port initialization.

void
USART3_Config(void)
{
UartDataRecvQueue = xQueueCreate(USART_3_BUFFER_SIZE, sizeof(uint8_t));
USART3_Gpio_Config();

USART_InitTypeDef USART_InitStructure;
RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART3, ENABLE);

USART_InitStructure.USART_BaudRate = 921600;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No;
USART_InitStructure.USART_HardwareFlowControl =
USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;

USART_Init(USART3, &USART_InitStructure);
USART_ITConfig(USART3, USART_IT_RXNE, ENABLE);

USART_Cmd(USART3, ENABLE);
while (USART_GetFlagStatus(USART3, USART_FLAG_TXE) != SET)
;
}
