编写程序，串接收完10个字口数据，转发给pc

好的，以下是一个简单的串口接收10个字节数据并转发给PC的Python示例代码，您可以参考：

import serial
import time

ser = serial.Serial('COM1', 9600) # 根据实际情况修改串口号和波特率
count = 0
data = []

while count < 10:
    if ser.in_waiting:
        byte = ser.read()
        data.append(byte)
        count += 1
    time.sleep(0.1) # 防止数据读取过快导致缓冲区溢出等问题

ser.close()

with open('data.txt', 'wb') as f:
    f.write(b''.join(data)) # 将数据写入文件中

with open('data.txt', 'rb') as f:
    data = f.read()

ser = serial.Serial('COM2', 9600) # 根据实际情况修改串口号和波特率
ser.write(data) # 将数据发送给PC
ser.close()

该代码使用Python的`serial`模块实现串口数据的接收和发送。它首先从串口读取10个字节数据，然后将数据写入文件中，最后再从文件读取数据并发送到另一个串口，即发送给PC。请注意，此示例代码仅供参考，实际情况需要根据具体要求进行修改和优化。

使用stm32f103c8t6单片机写一个串口透传程序

以下是一个使用stm32f103c8t6单片机编写的串口透传程序，该程序可以通过串口把收到的数据原封不动地转发到另一个串口。

首先，需要在CubeMX中配置单片机的USART1和USART2模块。设置为115200波特率，8位数据位，无校验位和1个停止位。

然后，在main.c中添加以下代码：

#include "stm32f1xx_hal.h"
#include "string.h"

void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_USART1_UART_Init(void);
static void MX_USART2_UART_Init(void);
void Error_Handler(void);

UART_HandleTypeDef huart1;
UART_HandleTypeDef huart2;

char buffer[100];

int main(void)
{
  HAL_Init();
  SystemClock_Config();
  MX_GPIO_Init();
  MX_USART1_UART_Init();
  MX_USART2_UART_Init();

  while (1)
  {
    memset(buffer, 0, sizeof(buffer));
    HAL_UART_Receive(&huart1, (uint8_t *)buffer, 100, 1000);
    HAL_UART_Transmit(&huart2, (uint8_t *)buffer, strlen(buffer), 1000);
  }
}

void SystemClock_Config(void)
{
  RCC_OscInitTypeDef RCC_OscInitStruct = {0};
  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

  /** Configure the main internal regulator output voltage 
  */
  __HAL_RCC_PWR_CLK_ENABLE();
  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);
  /** Initializes the CPU, AHB and APB busses clocks 
  */
  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
  RCC_OscInitStruct.HSIState = RCC_HSI_ON;
  RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI_DIV2;
  RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL16;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    Error_Handler();
  }
  /** Initializes the CPU, AHB and APB busses clocks 
  */
  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_SYSCLK
                                | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2;
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_USART1_UART_Init(void)
{

  huart1.Instance = USART1;
  huart1.Init.BaudRate = 115200;
  huart1.Init.WordLength = UART_WORDLENGTH_8B;
  huart1.Init.StopBits = UART_STOPBITS_1;
  huart1.Init.Parity = UART_PARITY_NONE;
  huart1.Init.Mode = UART_MODE_TX_RX;
  huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
  huart1.Init.OverSampling = UART_OVERSAMPLING_16;
  if (HAL_UART_Init(&huart1) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_USART2_UART_Init(void)
{

  huart2.Instance = USART2;
  huart2.Init.BaudRate = 115200;
  huart2.Init.WordLength = UART_WORDLENGTH_8B;
  huart2.Init.StopBits = UART_STOPBITS_1;
  huart2.Init.Parity = UART_PARITY_NONE;
  huart2.Init.Mode = UART_MODE_TX_RX;
  huart2.Init.HwFlowCtl = UART_HWCONTROL_NONE;
  huart2.Init.OverSampling = UART_OVERSAMPLING_16;
  if (HAL_UART_Init(&huart2) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_GPIO_Init(void)
{

  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOA_CLK_ENABLE();

  /*Configure GPIO pins : PC13 PC14 PC15 */
  GPIO_InitTypeDef GPIO_InitStruct = {0};
  GPIO_InitStruct.Pin = GPIO_PIN_13 | GPIO_PIN_14 | GPIO_PIN_15;
  GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);

  /*Configure GPIO pin : PA0 */
  GPIO_InitStruct.Pin = GPIO_PIN_0;
  GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
}

void Error_Handler(void)
{

}

该程序通过在一个while循环中，调用HAL_UART_Receive()函数从USART1串口接收数据，并且把它们存在缓冲区buffer中。随后使用HAL_UART_Transmit()函数把缓冲区中的数据透传到USART2串口中。程序也可以更改为通过USART2接收数据并在USART1接收的串口打印输出。

程序需要调用HAL库的一些函数，因此需要在main.c中添加以下头文件：

#include "stm32f1xx_hal.h"
#include "string.h"

需要注意的是，在stm32f103c8t6单片机中，USART1的引脚是PA9（TX）和PA10（RX），USART2的引脚是PA2（TX）和PA3（RX）。如果需要更改引脚，需要在CubeMX中重新配置。
