    以下回答参考 皆我百晓生、券券喵儿 等免费微信小程序相关内容作答，并由本人整理回复。

    您的代码存在一些问题，主要体现在以下几个方面：

    1. 您的Delay10ms()函数没有正确实现，它应该在1ms内重复调用。

    2. read_temp()函数中的计算逻辑有误，应根据您提供的read_temp()函数进行调整。

    3. display()函数中，对于数码管的显示，你需要确保每次读取到的新值都被正确地存储在变量temp中。

    4. 在关键的部分，例如温度转换、判断温度区间等，你可能需要添加更多的条件语句来确保正确的逻辑。

    5. 温度范围的限制和最小温度的限制也需要进一步考虑。

    下面我将为您纠正这些问题，并提供一个修复后的版本供参考：
