2. createNestedArray —— 在当前对象中添加子key,子value为json数组 StaticJsonDocument<256>doc;JsonObjectroot=doc.to<JsonObject>();root["status"]="on";JsonArraylevels=root.createNestedArray("levels");levels.add(10);levels.add(30);serializeJsonPretty(root,Serial); 结果: {"status":"on","le...
// Otherwise, add the incoming byte to the array: if (firstContact == false) { if (inByte == 'A') { myPort.clear(); // clear the serial port buffer firstContact = true; // you've had first contact from the microcontroller myPort.write('A'); // ask for more } } else { ...
doc["myChar"] = "hello"; //添加一个字符串对象节点 JsonArray myA = doc.createNestedArray("myArray"); //添加一个数组节点 myA.add(true); //使用add方式添加数据到JsonArray myA.add(false); JsonObject myO = doc.createNestedObject("myObject"); //添加一个对象节点 myO["myNumber"] = 1234...
void setup() { char my_str[6]; // an array big enough for a 5 character string Serial.begin(9600); my_str[0] = 'H'; // the string consists of 5 characters my_str[1] = 'e'; my_str[2] = 'l'; my_str[3] = 'l'; my_str[4] = 'o'; my_str[5] = 0; // 6th a...
// advance to the next position in the array: readIndex = readIndex + 1;数组每次加1。 communciation ASCIItable while (!Serial) { ; // wait for serial port to connect. Needed for native USB port only }。没有串口连接就不往下执行,进入死循环。主要用在setup()函数中。
