ArduinoJson on Energia about arduinojson HOT 8 CLOSED

Is there an alternative to using stdlib?

from arduinojson.

Yes, actually strtod is not used when compiling with Arduino.

Look at Print.h and Print.cpp.
They both contains a condition that makes them different for Arduino:

#ifndef ARDUINO

We have to change this condition so that the code for Arduino is also used for Energia.

To fix this, edit Print.hand Print.cppand replace ARDUINO by ENERGIA.
This should do the trick.

Please and tell me if it works so I can update the library. 👍

I dig a bit deeper, and msp430 stdlib doesn't have strtod function.
This method is used only once in your library. I commented that part out, so I will not be able to get float values, but otherwise rest of the code is working.

Did you see my answer?

from arduinojson.

Yeah, but right now I'm occupied with another issue. Following code snippet works fine

char json [] = "{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}";
JsonParser<16> parser;
JsonObject root = parser.parse(json);

but when instead of char array, I make a char pointer
char *json = "{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}";
it doesn't.
I've not looked at the library yet, but in most of the cases, there will be a pointer to data rather than data stored in an array.
May be you might like to give some input/patch

from arduinojson.

It can be a char*, but the memory must be writeable because the JSON parser will insert '\0' and remove escape sequences.

The problem with:

char *json = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";

is that the compiler gives you a pointer to a read-only area. It's really an issue with this construction, not with char*.

Please see http://stackoverflow.com/a/1704433/1164966

You won't have any issue if you give a char* pointing to a buffer you allocated.

PS: I found an old LaunchPad MSP430, I'll try Energia as soon as I can.

To your earlier post,
There doesn't exist this define. Apart from this define, everything else is working like a charm.
The pointer Issues which I was facing, got resolved by reading more about cc3100 and the structs it uses.
Thanks for the library.
Cheers Dude!!

I downloaded the latest version of Energia from nergia.nu.
I can now confirm that both ARDUINO and ENERGIA are defined.
The examples compiles fine without any modification.
