int begin(const char* ssid); ``` 这是一个函数的声明,名为 `begin`,返回类型为 `int`,接受一个参数 `const char* ssid`,该参数是指向字符数组(字符串)的指针,用于指定WiFi网络的SSID(Service Set Identifier)。在Arduino中,通常使用 `begin` 函数来初始化某个模块或者对象的配置。 ```cpp /* Start W...

These functions are faster than the previous ones. They differ from the original Arduino functions by the type of pin parameter - they useGPIO_pin_tinstead ofuint8_t(orint). So in your program, you define the pin as GPIO_pin_t pin = DP1; ...
