int i=1; uint8_t Pwd_ValidFlag = 0xA5; uint8_t Pwd_ValidFlagClear = 0x00; uint16_t Pwd_valid_address = ADDR_SETTING_LED_PWD_DATETIME+EEPROM_SETTING_LED_PWD_SIZE-7; for(i=1;i<=10;i++) { Setting_Led_Get_Pwd_LastValid(Pwd_valid_address, &Pwd_last_valid); if(i == 10) { Pwd_last_group = 0; Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME+(Pwd_last_group * 7),&Pwd_ValidFlag); break; } if (Pwd_last_valid == 0xA5) { Pwd_last_group = 10 - i; Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME+(Pwd_last_group * 7),&Pwd_ValidFlagClear); Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME+(Pwd_last_group * 7)+7,&Pwd_ValidFlag); break; } Pwd_valid_address = Pwd_valid_address - 7; } abTime[0] = g_stcPanel.stcRTCGet.Year; abTime[1] = g_stcPanel.stcRTCGet.Month; abTime[2] = g_stcPanel.stcRTCGet.Day; abTime[3] = g_stcPanel.stcRTCGet.Hour; abTime[4] = g_stcPanel.stcRTCGet.Minute; abTime[5] = g_stcPanel.stcRTCGet.Second; Setting_Led_Set_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME+(Pwd_last_group * 7)+7+1,abTime); Setting_Led_Get_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME+(Pwd_last_group * 7)+1,abTime2);要求7x10=70，留出10组，分别为0-9，每组7个字节，第1个字节存有效性标志0xA5，后6个字节存储日期时间，每次轮询0xA5标志，清零标志，在下一个组写入标志与日期时间，第十组写完后，下一次从第一组开始，请根据上面给出的部分代码进行完善和优化

根据需求，需要对给出的部分代码进行完善和优化，以下是一个可能的实现方案：

1. 在代码开头，定义常量和变量，用于存储密码数据的地址、有效性标志和日期时间等信息：

#define ADDR_SETTING_LED_PWD_DATETIME 0x8000 // 密码数据的存储地址，假设为0x8000
#define EEPROM_SETTING_LED_PWD_SIZE 70 // 密码数据总大小，假设为70字节

uint8_t pwd_valid_flag = 0xA5; // 密码有效性标志
uint8_t pwd_valid_flag_clear = 0x00; // 密码有效性标志清零值
uint8_t pwd_last_valid; // 上一个密码数据的有效性标志
uint8_t pwd_last_group = 0; // 上一个密码数据所在的组号，初始为0
uint16_t pwd_valid_address = ADDR_SETTING_LED_PWD_DATETIME + EEPROM_SETTING_LED_PWD_SIZE - 7; // 上一个密码数据的地址，初始为最后一个组的起始地址
uint8_t abTime[6]; // 当前时间，用于更新密码数据的日期时间信息
uint8_t abTime2[6]; // 读取到的密码数据的日期时间信息，用于检查写入是否成功

2. 在一个循环中轮询密码数据，找到上一个有效的密码数据的组号和地址，并清除其有效性标志：

for (int i = 1; i <= 10; i++) {
    Setting_Led_Get_Pwd_LastValid(pwd_valid_address, &pwd_last_valid);
    if (i == 10) {
        pwd_last_group = 0;
        Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag);
        break;
    }
    if (pwd_last_valid == pwd_valid_flag) {
        pwd_last_group = 10 - i;
        Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag_clear);
        break;
    }
    pwd_valid_address -= 7;
}

3. 更新密码数据的日期时间信息，写入有效性标志和日期时间到下一个组：

abTime[0] = g_stcPanel.stcRTCGet.Year;
abTime[1] = g_stcPanel.stcRTCGet.Month;
abTime[2] = g_stcPanel.stcRTCGet.Day;
abTime[3] = g_stcPanel.stcRTCGet.Hour;
abTime[4] = g_stcPanel.stcRTCGet.Minute;
abTime[5] = g_stcPanel.stcRTCGet.Second;

Setting_Led_Set_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 7 + 1, abTime);
Setting_Led_Get_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 1, abTime2);

pwd_last_group = (pwd_last_group + 1) % 10; // 更新上一个密码数据所在的组号为下一个组
Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag);

4. 重复上述过程，直到所有的密码数据都被写入：

for (int i = 1; i <= 9; i++) {
    pwd_valid_address -= 7;
    Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 7, &pwd_valid_flag_clear);
    abTime[0] = 0;
    abTime[1] = 0;
    abTime[2] = 0;
    abTime[3] = 0;
    abTime[4] = 0;
    abTime[5] = 0;
    Setting_Led_Set_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 7 + 1, abTime);
    Setting_Led_Get_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 1, abTime2);
    pwd_last_group = (pwd_last_group + 1) % 10;
    Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag);
}

完整的代码如下所示：

#define ADDR_SETTING_LED_PWD_DATETIME 0x8000 // 密码数据的存储地址，假设为0x8000
#define EEPROM_SETTING_LED_PWD_SIZE 70 // 密码数据总大小，假设为70字节

uint8_t pwd_valid_flag = 0xA5; // 密码有效性标志
uint8_t pwd_valid_flag_clear = 0x00; // 密码有效性标志清零值
uint8_t pwd_last_valid; // 上一个密码数据的有效性标志
uint8_t pwd_last_group = 0; // 上一个密码数据所在的组号，初始为0
uint16_t pwd_valid_address = ADDR_SETTING_LED_PWD_DATETIME + EEPROM_SETTING_LED_PWD_SIZE - 7; // 上一个密码数据的地址，初始为最后一个组的起始地址
uint8_t abTime[6]; // 当前时间，用于更新密码数据的日期时间信息
uint8_t abTime2[6]; // 读取到的密码数据的日期时间信息，用于检查写入是否成功

for (int i = 1; i <= 10; i++) {
    Setting_Led_Get_Pwd_LastValid(pwd_valid_address, &pwd_last_valid);
    if (i == 10) {
        pwd_last_group = 0;
        Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag);
        break;
    }
    if (pwd_last_valid == pwd_valid_flag) {
        pwd_last_group = 10 - i;
        Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag_clear);
        break;
    }
    pwd_valid_address -= 7;
}

abTime[0] = g_stcPanel.stcRTCGet.Year;
abTime[1] = g_stcPanel.stcRTCGet.Month;
abTime[2] = g_stcPanel.stcRTCGet.Day;
abTime[3] = g_stcPanel.stcRTCGet.Hour;
abTime[4] = g_stcPanel.stcRTCGet.Minute;
abTime[5] = g_stcPanel.stcRTCGet.Second;

Setting_Led_Set_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 7 + 1, abTime);
Setting_Led_Get_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 1, abTime2);

pwd_last_group = (pwd_last_group + 1) % 10;
Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag);

for (int i = 1; i <= 9; i++) {
    pwd_valid_address -= 7;
    Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 7, &pwd_valid_flag_clear);
    abTime[0] = 0;
    abTime[1] = 0;
    abTime[2] = 0;
    abTime[3] = 0;
    abTime[4] = 0;
    abTime[5] = 0;
    Setting_Led_Set_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 7 + 1, abTime);
    Setting_Led_Get_Pwd_DateTime(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7) + 1, abTime2);
    pwd_last_group = (pwd_last_group + 1) % 10;
    Setting_Led_Set_Pwd_Valid(ADDR_SETTING_LED_PWD_DATETIME + (pwd_last_group * 7), &pwd_valid_flag);
