STM32开发板的TFTLCD显示屏显示串口发送过来的数据的标准库函数版本代码？

以下是使用STM32标准库函数驱动TFTLCD显示屏显示串口发送过来的数据的示例代码：

#include "stm32f10x.h"
#include "stm32f10x_usart.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_rcc.h"
#include "stm32f10x_spi.h"
#include "stm32f10x_dma.h"
#include "stm32f10x_adc.h"
#include "stm32f10x_tim.h"
#include "stm32f10x_exti.h"

#include "ili9341.h"

#define USARTx                       USART1
#define USARTx_IRQn                  USART1_IRQn
#define USARTx_IRQHandler            USART1_IRQHandler

/**
  * @brief  Configure the USART1 pins.
  * @param  None
  * @retval None
  */
void USART_Configuration(void)
{
  GPIO_InitTypeDef GPIO_InitStructure;
  USART_InitTypeDef USART_InitStructure;

  /* Enable GPIO clock */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

  /* Enable USART clock */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);

  /* Configure USART1 Rx (PA10) as input floating */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  /* Configure USART1 Tx (PA9) as alternate function push-pull */

  GPIO_Init(GPIOA, &GPIO_InitStructure);

  /* USART1 configuration ------------------------------------------------------*/
  /* USART1 configured as follow:

        - Word Length = 8 Bits
        - One Stop Bit

        - Hardware flow control disabled (RTS and CTS signals)
        - Receive and transmit enabled
  */
  USART_InitStructure.USART_BaudRate = 115200;
  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(USARTx, &USART_InitStructure);

  /* Enable USART1 */
  USART_Cmd(USARTx, ENABLE);
}

/**
  * @brief  Send a string to the USART.
  * @param  s: pointer to string
  * @retval None
  */
void USART_puts(USART_TypeDef* USARTx, volatile char *s)
{
  while(*s)
  {
    // wait until data register is empty
    while(USART_GetFlagStatus(USARTx, USART_FLAG_TXE) == RESET);

    // send data
    USART_SendData(USARTx, *s);

    // next byte
    s++;
  }
}

int main(void)
{
  USART_Configuration();

  ILI9341_Init();
  ILI9341_setRotation(1);
  ILI9341_fillScreen(ILI9341_BLACK);

  char buffer[50];
  while (1)
  {
    // wait until data is received
    while (USART_GetFlagStatus(USARTx, USART_FLAG_RXNE) == RESET);

    // read data
    char data = USART_ReceiveData(USARTx);

    // convert data to string
    sprintf(buffer, "Received: %c", data);

    // display string on LCD
    ILI9341_setTextColor(ILI9341_WHITE);
    ILI9341_setCursor(0, 0);
    ILI9341_puts(buffer);

    // send data back to serial port
    USART_puts(USARTx, buffer);
  }
}

这段代码使用USART1接收串口数据，并将接收到的数据转换为字符串，然后在TFTLCD显示屏上显示该字符串，并将该字符串发送回串口。
