我有一个ESP-32 Wi-Fi模块- Lolin32和一个Benetech GM8904 UART风速表
风速表使用说明的完整版本在这里．
我把4根电线从风速表连接到控制器。
我将黑线连接到GND，绿色RX连接到GPIO3，白色TX连接到GPIO1，红色电源连接到5V
代码Yaml在EspHome

怎么了?
为什么数据不是来自UART?
这里描述了一个非常相似的情况帖子．最后的解决方案是使用UART1。
我读过有关它的书，尝试过各种方法。
将uart1添加到yaml记录器代码
GPIO 1.3改为16.17…
我发现UART1需要使用GPIO10和GPIO11的信息，但是我找不到它们在ESP板上的位置。
也许你需要用一个电阻器?
我在这方面还太缺乏经验，请帮助。
