hello
I have problem when convert DynamicJsonBuffer in my code from arduinojson 5 to arduinojson 6 , i need to resolve it without install libraries to version 5.13 , i know there are way by replace DynamicJsonDocument , i am try more than one time but the code is not work , i need help to replace DynamicJsonDocument in my code instead of DynamicJsonBuffer.
this my code i need to convert it to DynamicJsonDocument , i will show the the two part in the code which i need to solve it , if anyone need to show the full code i will upload it
if (SPIFFS.begin()) {
Serial.println("mounted file system");
if (SPIFFS.exists("/config.json")) {
Serial.println("reading config file");
File configFile = SPIFFS.open("/config.json", "r");
if (configFile) {
Serial.println("opened config file");
size_t size = configFile.size();
std::unique_ptr<char[]> buf(new char[size]);
configFile.readBytes(buf.get(), size);
DynamicJsonBuffer jsonBuffer;
JsonObject& json = jsonBuffer.parseObject(buf.get());
json.printTo(Serial); //print config data to serial on startup
if (json.success()) {
Serial.println("\nparsed json");
strcpy(MyApiKey, json["MyApiKey"]);
strcpy(deviceID_1, json["deviceID_1"]);
strcpy(deviceID_2, json["deviceID_2"]);
strcpy(deviceID_3, json["deviceID_3"]);
} else {
Serial.println("failed to load json config");
initialConfig = true;
}
}
}
} else {
Serial.println("failed to mount FS");
}
and this the second part
if (shouldSaveConfig) {
Serial.println("saving config");
DynamicJsonBuffer jsonBuffer;
JsonObject& json = jsonBuffer.createObject();
json["MyApiKey"] = MyApiKey
json["deviceID_1"] = deviceID_1;
json["deviceID_2"] = deviceID_2;
json["deviceID_3"] = deviceID_3;
File configFile = SPIFFS.open("/config.json", "w");
if (!configFile) {Serial.println("failed to open config file for writing");}
json.prettyPrintTo(Serial);
json.printTo(configFile);
configFile.close();
Serial.println("config saved");
shouldSaveConfig = false;
initialConfig = false;
ticker.detach();
digitalWrite(status_led, HIGH);
WiFi.mode(WIFI_STA);
ESP.restart();
delay(5000);
}
