style="line-height:1.8">第一个问题</p> <p style="line-height:1.8">SHT40温湿度传感器数据读取的过程种存在的问题，就是在I2C上拉电阻处存在虚焊，在一开始软件调试的时候一直找不到问题，一开始以为传感器问题，但是后面通过检查I2C两个引脚的电压，发现了有一个引脚因为上拉电阻问题导致无法正常工作。</p> <p style="line-height:1.8">第二个问题</p> <p style="line-height:1.8">第二个问题也是虚焊问题，我使用的是LCD1602显示屏进行显示，在调试过程中，总有一个引脚电压不稳定，显示的是供电电压，一开始也以为是LCD1602屏幕坏了，还买了一个，后面通过一个引脚一个引脚的单独输出高电平，有一个引脚无法正常输出电平，结果是主控芯片的引脚没焊好所导致的。</p> <p style="line-height:1.8"> </p>
