    @suslucoder well, you could only save the data as a json file, on program close, or something similar.

    Fits your requirement and he will never know that the actual data processing/storage is something different.

    Doesn't hurt to have redundancies either.

    Good idea; this helps avoid the performance issues and hard drive wearing. Beware though: If the program crashes, all of the data will be lost.

      @JKSH i spoke with him, he says he wants a config file with json.

      It should include the name of the data, and the type. Like
      Name: string
      Age: int
      Height:float etc.

      I dont know how to create such a file

        ROFL. Are you now advising Qt programmers to deceive their bosses? ;-)

        What don't you know how to do? You have done JSON stuff, haven't you, so what is different about this task?

          Have you tried to read JSON documentation?

          ==> https://doc.qt.io/qt-5/qtcore-serialization-savegame-example.html

            😱 me, never!

            The boss will get what he want's, in the end. Bosses always only care about the end result 🤷‍♂️

                @JonB actually, ı know, i created it with hand, but my question is we have something like

                #define TM_AP_ID				0
                #define TM_AP_durum 			1
                #define TM_AP_hava_hizi			2
                #define TM_AP_IMU_pitch			3
                #define TM_AP_IMU_roll			4
                #define TM_AP_IMU_yaw			5
                #define TM_AP_IMU_barometre		6
                #define TM_AP_rpm				7
                
                

                and in my code, i will do some operations like

                imu[TM_IMU_pitch].f
                
                

                The issue is, that definitions should be in json, and i will call them from my json

                  What definitions? You can't call anything from JSON. JSON is just a data format. Please be more precise when asking...

                          So, all these definitions should be defined in your JSON? Then do so. Define them there, read and use the values.

                            @jsulm I defined it in json.
                            I want to do that: Here is an example of my json

                              @jsulm I defined it in json.
                              I want to do that: Here is an example of my json

                              {
                                       "GPS":[

                                                "0"
                                             ],
                                             "GPS Mod":[
                                                "integer",
                                                "1"
                                             ],
                                             "GPS Utc":[
                                                "float",

                              }
                              
                              If, Gps id has integer, 
                              assign gps[TM_GPS_ID].i

                              So algorithmically you will want something like:

                              if "GPS" object  has "GPS ID" array
                                  if "GPS ID" array[0] == "integer"
                                      gps[TM_GPS_ID].i = "GPS ID" array[1].toInt()
                              if "GPS" object  has "GPS Latitude" array
                                  if "GPS Latitude" array[0] == "float"
                                      gps[TM_GPS_lat].f = "GPS Latitude" array[1].toFloat()

                                  @suslucoder said in Real Time data and Json File:

                                  if "GPS" object has arrays contains "float"

                                  if "GPS " object has arrays contains "integer"

                                  So implement exactly these tests. Someone has even typed in code for you in your stackoverflow post. I don't know what else to say.
