我想要stm32WLE5CCCU6的PA11连接I2C2_SDA，PA12连接I2C2_SCL，从而控制CHTA30IW的完整代码

好的，以下是控制CHTA30IW的完整代码，其中PA11连接I2C2_SDA，PA12连接I2C2_SCL，使用的是STM32的HAL库：

#include "stm32wle5xx_hal.h"

#define CHTA30IW_ADDRESS 0x40

I2C_HandleTypeDef hi2c2;

void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_I2C2_Init(void);

int main(void)
{
  HAL_Init();
  SystemClock_Config();
  MX_GPIO_Init();
  MX_I2C2_Init();

  uint8_t data[2];
  data[0] = 0x01; // set control byte to enable measurement
  data[1] = 0x00; // set measurement range to +/- 4g
  HAL_I2C_Master_Transmit(&hi2c2, CHTA30IW_ADDRESS, data, 2, HAL_MAX_DELAY);

  while (1)
  {
    HAL_I2C_Master_Receive(&hi2c2, CHTA30IW_ADDRESS, data, 2, HAL_MAX_DELAY);

    // convert data to acceleration values
    int16_t x = (data[0] << 8) | data[1];
    float x_accel = (float)x / 8192.0f;

    // do something with the acceleration values
    // ...

    HAL_Delay(100); // wait for next read
  }
}

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

  /** Initializes the RCC Oscillators according to the specified parameters
  * in the RCC_OscInitTypeDef structure.
  */
  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;
  RCC_OscInitStruct.HSIState = RCC_HSI_ON;
  RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    Error_Handler();
  }
  /** Initializes the CPU, AHB and APB buses clocks
  */
  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_SYSCLK
                              | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSI;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_1) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_I2C2_Init(void)
{
  hi2c2.Instance = I2C2;
  hi2c2.Init.Timing = 0x10909CEC;
  hi2c2.Init.OwnAddress1 = 0;
  hi2c2.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT;
  hi2c2.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE;
  hi2c2.Init.OwnAddress2 = 0;
  hi2c2.Init.OwnAddress2Masks = I2C_OA2_NOMASK;
  hi2c2.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;
  hi2c2.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE;
  if (HAL_I2C_Init(&hi2c2) != HAL_OK)
  {
    Error_Handler();
  }
  if (HAL_I2CEx_ConfigAnalogFilter(&hi2c2, I2C_ANALOGFILTER_ENABLE) != HAL_OK)
  {
    Error_Handler();
  }
  if (HAL_I2CEx_ConfigDigitalFilter(&hi2c2, 0) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_GPIO_Init(void)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};

  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOA_CLK_ENABLE();

  /* Configure GPIO pins : PA11 PA12 */
  GPIO_InitStruct.Pin = GPIO_PIN_11|GPIO_PIN_12;
  GPIO_InitStruct.Mode = GPIO_MODE_AF_OD;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
  GPIO_InitStruct.Alternate = GPIO_AF5_I2C2;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
}

以上代码中，我们在主函数中进行了如下操作：

1. 初始化I2C2通信接口。
2. 通过I2C2向CHTA30IW写入控制字节和测量范围。
3. 不断从CHTA30IW读取加速度数据，并将其转换为实际的加速度值并进行处理。

在代码中，我们使用了STM32的HAL库来进行I2C通信和GPIO配置。你可以根据需要进行修改。

注意，在将代码烧录到STM32WLE5CCCU6芯片之前，请确保已正确连接CHTA30IW，并按照CHTA30IW的数据手册配置其I2C地址、控制字节和测量范围等参数。
