extern void GPIO_interruptEdgeSelect(uint_fast8_t selectedPort, uint_fast16_t selectedPins, uint_fast8_t edgeSelect);

这是一个外部函数声明,声明了一个名为`_interruptEdgeSelect`的函数该函数用于配置GPIO口的中断触发边沿。
该函数接受三个参数:
- `selectedPort`:指定GPIO口的端口号。
- `selectedPins`:指定GPIO口的引脚号。
- `edgeSelect`:指定中断触发的边沿类型。
根据这个声明,`GPIO_interruptEdgeSelect`函数可能是一个用于配置GPIO口中断的函数。具体的实现可能在其他地方定义。
要使用这个函数,你需要确保已经包含了声明所需的头文件,并在代码中调用该函数,传递适当的参数。例如:
```c
GPIO_interruptEdgeSelect(GPIO_PORT_P1, GPIO_PIN1, GPIO_HIGH_TO_LOW_TRANSITION);
```
这个示例调用了`GPIO_interruptEdgeSelect`函数,将P1.1引脚配置为高到低的边沿触发中断。
请注意,这只是函数声明,并没有提供函数的具体实现细节。如果要使用该函数,你需要查找或提供其实际的定义或实现。

在你提供的代码中,没有包含头文件 "main.h" 和 "stdio.h"。你需要添加这两个头文件到你的代码中,这样才能正确使用其中的函数和变量。
另外,你在调用 sprintf 函数时,第二个参数类型应该是 char*,而不是 uint8_t*。因此,你需要将 aTXbuf 声明为 char 类型数组,而不是 uint8_t 类型数组。同时,在使用 strlen 函数计算字符串长度时,应该传入一个 char* 类型的参数。
最后,你可以将 DHT11_Read_Data 函数的返回值直接返回,而不需要使用 if-else 语句判断后再返回。因为函数内部已经有了返回值,可以直接将其返回给调用者。
