📟 JSON library for Arduino and embedded C++. Simple and efficient.
```c++ StaticJsonDocument doc; doc.set(1.7976931348623147e+308); serializeJson(doc, std::cout); // 1.797693135e308 ``` Online demo: https://wandbox.org/permlink/sJfBXevl6vd3KDL5 The rounding is correct, but the value is out of `double`'s range. This can be an issue because...
I have an application that fetches a json file from an http server and extracts a value from the json. The url (and therefore the structure of the json) is...
Hi, I wrote a sample .ino to demonstrate the challenge from [https://github.com/bblanchon/ArduinoJson/issues/1309](url) with descriptions in the serial printout. File is here: https://gist.github.com/jshep321/2b9ffb745edfa9dc121257656d811a07 Note that for the json format I would...
Would it be interesting to add a configuration to disable support for floats to reduce the flash size? In my arduino code I avoid using them but when I check...
I'm storing configuration in SPIFFS and so I have to size the `DynamicJsonDocument` large enough that it won't unexpectedly fail to read/write the whole configuration file. The problem I have...
It would be nice if the functions / methods serialzeJson() and deserializeJson() would be extended, so that it is possible to use them directly on nested Objects (and not only...
I have read through the API docs but didn't find such a basic functionality so I have to implement my own. A `containsElement` method would help: ``` jsonArray.containsElement("third") // ==...
Currently, [it is not possible to rename an object key efficiently](https://github.com/bblanchon/ArduinoJson/issues/977#issuecomment-489309197). However, renaming an object key can be handy at times. For example, I am currently implementing a [Json-RPC library](https://gitlab.com/tue-umphy/co2mofetten/arduino-libraries/ArduinoJsonRPC)....
I'm using a library for an external RAM. Currently i can write and read char arrays like this: ```cpp SRAM.writeBlock(START_ADDRESS, size, (void*)buff); SRAM.readBlock(START_ADDRESS, size, buff); ``` **The underlying code in...
