Still having issues with serialization.

[jbasiago]

Sorry to bug you again, but I'm really perplexed. I updated the code that I really want to serialize and tried to run it. But each time it runs, the processor exceptions out and restarts at the point of serializing the document. I know its not a memory issue because the code is so short. Can you give me any advice on this matter. Just so yo u can look at the code to check for errors, here it is.

I hate to waste you time, but I really would appreciate a little.
Thanks in advance.

#include <Arduino.h>
#include "ArduinoJson.h"
#include "PinConfig.h"

struct Board {
    std::vector<PinConfig *> analog {};
    std::vector<PinConfig *> digital {};
};

Board systemBoards[4] {};

void setup() {
    Serial.begin(115200);
    Serial.println();
    Serial.println("Starting application");

    JsonDocument doc;
    JsonObject saveToFile = doc["saveToFile"].to<JsonObject>();
    saveToFile["controllerId"] = 1;
    saveToFile["trackPowerMonitorId"] = "Reset1";
    saveToFile["stateSendMonitorId"] = "Send2";

    JsonArray boards = saveToFile["boards"].to<JsonArray>();

    for (unsigned int address = 0; address < 1; address++) {
        JsonObject board = doc["board"].to<JsonObject>();
        boards.add(board);
        board["address"] = address;
        board["analog"] = doc.to<JsonArray>();
        board["digital"] = doc.to<JsonArray>();

        for (auto pinConfig : systemBoards[address].analog) {
            auto board_pinConfig = board["analog"].add<JsonObject>();
            board_pinConfig["firstPin"] = pinConfig->firstPin;
            auto it = pinStringTable.find(pinConfig->pinType);
            if (it != pinStringTable.end()) {
                board_pinConfig["type"] = it->second;
            }
            board_pinConfig["id"] = pinConfig->id;
            if (strlen(pinConfig->actuatorId) > 0) {
                board_pinConfig["actuatorId"] = pinConfig->actuatorId;
            }
            if (pinConfig->onWidth) {
                board_pinConfig["onWidth"] = pinConfig->onWidth;
            }
        }

        for (auto pinConfig : systemBoards[address].digital) {
            auto board_pinConfig = board["digital"].add<JsonObject>();
            board_pinConfig["firstPin"] = pinConfig->firstPin;
            auto it = pinStringTable.find(pinConfig->pinType);
            if (it != pinStringTable.end()) {
                board_pinConfig["type"] = it->second;
            }
            board_pinConfig["id"] = pinConfig->id;
        }
    }
    String result;
    serializeJson(saveToFile, result);
    Serial.println(result);
}

void loop() {
// write your code here
}

Hi @jbasiago,

Did you try the ArduinoJson Troubleshooter?

Best regards,
Benoit

I looked at my code again and found some errors that took care of the problem. I will check out ArduinoJson Troubleshooter which I was not aware of.

Thanks again,
Jack
