- #include <ArduinoJson.h>
- void setup() {
- // Initialize Serial port
- Serial.begin(9600);
- while (!Serial) continue;
- // Allocate the JSON document
- //
- // Inside the brackets, 200 is the RAM allocated to this document.
- // Don't forget to change this value to match your requirement.
- // Use arduinojson.org/v6/assistant to compute the capacity.
- StaticJsonDocument<200> doc;
- // StaticJsonObject allocates memory on the stack, it can be
- // replaced by DynamicJsonDocument which allocates in the heap.
- //
- // DynamicJsonDocument doc(200);
- // Add values in the document
- //
- doc["sensor"] = "gps";
- doc["time"] = 1351824120;
- // Add an array.
- //
- JsonArray data = doc.createNestedArray("data");
- data.add(48.756080);
- data.add(2.302038);
- // Generate the minified JSON and send it to the Serial port.
- //
- serializeJson(doc, Serial);
- // The above line prints:
- // {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
- // Start a new line
- Serial.println();
- // Generate the prettified JSON and send it to the Serial port.
- //
- serializeJsonPretty(doc, Serial);
- // The above line prints:
- // {
- // "sensor": "gps",
- // "time": 1351824120,
- // "data": [
- // 48.756080,
- // 2.302038

- // The book "Mastering ArduinoJson" contains a tutorial on serialization.
- // It begins with a simple example, like the one above, and then adds more
- // features like serializing directly to a file or an HTTP request.
