串口接收回调函数:void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart); 这个函数默认不会自动生成,需要我们自己写。 函数功能:当HAL_UART_Receive_IT函数结束后,会进来这个函数当中,用户可以在这个函数中对数据进行处理。 方便大家,给各位同学贴出我自己写的函数HAL_UART_RxCpltCallback if(huart->Instance=...
Android 应用将使用 Retrofit 库与 ESP8266 进行 REST API 通信。以下是 Android App 中的代码示例: 1. Retrofit API 接口 publicinterfaceEspApi{@POST("setWiFiConfig")Call<ResponseBody>setWiFiConfig(@BodyWiFiConfigconfig);}classWiFiConfig{privateStringssid;privateStringpassword;publicWiFiConfig(Stringssid,String...
display.drawPixel(10,10,WHITE); // Show the display buffer on the screen. You MUST call display() after // drawing commands to make them visible on screen! display.display(); delay(2000); // display.display() is NOT necessary after every single drawing command, // unless that's what ...

1importurequests Next, to perform the actual HTTP GET request, we simply need to call the get function of the urequests module, passing as input the URL of destination of the request. We will use a website with a fake online REST API, which I’ve used before in many tutorials. ...

In the sample application below, thecallbackfunction handles MQTT communication events and implements the main functionality: 42| void callback(char* topic, byte* payload, unsigned int length) { 43| Serial.print("Message arrived on topic: '"); ...
正如rest 参数将几个参数组合成一个数组一样, *spread 语法*将数组的内容分隔成单独的参数。Spread 语法使用与 rest 参数相同的三点语法。清单 2-18 中的函数对其参数的绝对值求和;它首先获取参数的绝对值,然后使用 spread 语法调用`add`函数来计算总和。 function addAbs(...values) { for (let i = 0;...
Note that the URL corresponds to the /posts route of the fake online REST api website mentioned in the introductory section. 1 response = urequests.post("http://jsonplaceholder.typicode.com/posts", data = "some dummy content") Note that this function call will return an object of class Re...
