Real Time data and Json File

[deleted286]

@JKSH he thinks that keeping datas on json == creating a config file. Like settings folder. But i know it isnt, so i dont know how can i handle with that issue

You could explain to him the disadvantages shown by @JKSH

@jsulm thank you

[J.Hilk]

@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.

[deleted286]

@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/json.html

😱 me, never!

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

@J-Hilk ahahahha you made me laugh so much

I create the file, but i dont know how to read such a complex json :D
Can anybody help?

   {
"GPS": [
    {

        "GPS ID": ["integer", "0"],
        "GPS Mod": ["integer", "1"],

@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...

[deleted286]

@jsulm

im talking about them

#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

Hmm, so im just read json and write json. I cant do anything apart from these

I can not follow you, what did you expect to do?
Do you know what JSON is? ==> https://en.wikipedia.org/wiki/JSON

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

[deleted286]

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

{
         "GPS":[
            {
               "GPS ID":[
                  "integer",
                  "0"
               ],
               "GPS Mod":[
                  "integer",
                  "1"
               ],
               "GPS Utc":[
                  "float",
                  "2"
               ],
               "GPS Latitude":[
                  "float",
                  "3"
               ]
}

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

if Gps latitude has float
assign  gps[TM_GPS_lat].f

[JonB]

@suslucoder
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()

[deleted286]

@JonB Let me edit it like

if "GPS" object has arrays contains "float"
     gps[TM_GPS_lat].f == "GPS ID" array[1].toInt()
     gps[TM_GPS_lat].f  == "GPS ID" array[1].toInt()

 if "GPS " object has arrays contains "integer"
     gps[TM_GPS_ID].i = "GPS ID" array[1].toInt()

gps[TM_GPS_lat].f
```  this f refers to float

gps[TM_GPS_ID].i
``` this i refers to int

[JonB]

@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.
