stm32 cubemx at24c64

这是一个关于STM32和AT24C64的问题。AT24C64是一种64K位的串行EEPROM存储器，而STM32是一种微控制器。Cubemx是一个用于生成STM32代码的图形化工具。

如果你想在STM32上使用AT24C64，你需要连接它们并编写相应的代码。你可以使用STM32的I2C接口来连接AT24C64，然后使用HAL库或者LL库来编写读写AT24C64的代码。

以下是一个使用HAL库读取AT24C64的示例代码：

#include "stm32f4xx_hal.h"

#define EEPROM_ADDRESS 0xA0

I2C_HandleTypeDef hi2c1;

void HAL_I2C_MspInit(I2C_HandleTypeDef* i2cHandle)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
  if(i2cHandle->Instance==I2C1)
  {
    /* I2C1 clock enable */
    __HAL_RCC_I2C1_CLK_ENABLE();
  
    __HAL_RCC_GPIOB_CLK_ENABLE();
    /**I2C1 GPIO Configuration    
    PB6     ------> I2C1_SCL
    PB7     ------> I2C1_SDA 
    */
    GPIO_InitStruct.Pin = GPIO_PIN_6|GPIO_PIN_7;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_OD;
    GPIO_InitStruct.Pull = GPIO_PULLUP;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF4_I2C1;
    HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);

    /* I2C1 interrupt Init */
    HAL_NVIC_SetPriority(I2C1_EV_IRQn, 0, 0);
    HAL_NVIC_EnableIRQ(I2C1_EV_IRQn);
    HAL_NVIC_SetPriority(I2C1_ER_IRQn, 0, 0);
    HAL_NVIC_EnableIRQ(I2C1_ER_IRQn);
  }
}

void HAL_I2C_MspDeInit(I2C_HandleTypeDef* i2cHandle)
{
  if(i2cHandle->Instance==I2C1)
  {
    /* Peripheral clock disable */
    __HAL_RCC_I2C1_CLK_DISABLE();
  
    /**I2C1 GPIO Configuration

    PB7     ------> I2C1_SDA 
    */
    HAL_GPIO_DeInit(GPIOB, GPIO_PIN_6|GPIO_PIN_7);

    /* I2C1 interrupt Deinit */
    HAL_NVIC_DisableIRQ(I2C1_EV_IRQn);
    HAL_NVIC_DisableIRQ(I2C1_ER_IRQn);
  }
}

  hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;
  hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE;
  if (HAL_I2C_Init(&hi2c1) != HAL_OK)
  {
    Error_Handler();
  }

}

void HAL_I2C_MemTxCpltCallback(I2C_HandleTypeDef *hi2c)
