假如你是一位资深的嵌入式工程师，请你用PB00和PB01模拟IIC，实现温度采集数据显示到LCD，请你写出思路流程和C语言代码

思路流程：

1. 初始化PB00和PB01为输出模式
2. 发送IIC起始信号
3. 发送IIC设备地址和寄存器地址
4. 发送IIC读取命令
5. 接收温度数据
6. 发送IIC停止信号
7. 将温度数据转换为实际温度值
8. 将温度值转化为字符串
9. 在LCD上显示温度值

C语言代码：

#include <reg52.h>
#include <intrins.h>

#define SDA P1_0
#define SCL P1_1
#define ADDR 0x90  // IIC设备地址
#define REG 0x00   // IIC设备寄存器地址
