写一个STM32L051C8T6的代码,使用HAL库,使用内部EEPROM存储,要求上电发送进入地址设置指令,进入地址设定状态,保证7个RGBLED灭,然后在对应地址放入瓶子,轮询三次,相应的RGBLED闪三下,LED闪三下一样的绿色则最后显示绿灯,LED闪三下不同的(绿色或红色)则最后显示红灯,显示绿灯则串口1显示正确的地址,显示红灯则不显,当地址设定正确后,地址设定状态结束,进入工作状态,运行其他工作代码

以下是一个可能的实现代码,需要根据具体硬件和接口进行调整:
```
#include "stm32l0xx_hal.h"
#include <string.h>
#define EEPROM_START_ADDR 0x08080000 // 内部EEPROM地址
#define ADDR_SET_CMD 0xA5 // 进入地址设置模式的指令
#define LED_PORT GPIOA
#define LED_PIN_1 GPIO_PIN_1
#define LED_PIN_2 GPIO_PIN_2
#define LED_PIN_3 GPIO_PIN_3
#define GREEN_LED_ON HAL_GPIO_WritePin(LED_PORT, LED_PIN_1, GPIO_PIN_RESET)
