Working on a little Halloween FastLED project. Wondering if anyone has had an experience working with any of the JSON parsing libraries available for arduino (such as: https://github.com/bblanchon/ArduinoJson).
Trying to trigger a variety of FastLED sequences based on responses from a variety of different APIs that luckily all offer JSON responses. Just curious if anyone has any pointers. First time working with JSON & Arduino. Thanks all!
I’ve used aJson before: https://github.com/interactive-matter/aJson
I looked at ArduinoJson a while back, and there are a few reasons why I went with aJSON instead. ArduinoJson didn’t seem to be able to read directly from a file or stream, you have to have the entire JSON message in memory. There may be a way, but I couldn’t find it.
You also had to specify in advance how many tokens it should be capable of reading, and thus how much static memory will be consumed by it, which isn’t terribly useful for loading large lists of arbitrary length.
@Jason_Coon introduced (via smartmatrix) me to aJSON, and i’ve never looked back.
Thank you gentlemen, I will definitely take a look!
And can I just add…“Damn you Facebook for all your changes!” It’s been about a year since I last did anything with their APIs and V2.5 is just different enough that the code I had hoped to just reuse needs to be updated much more than I hoped…grrrrrrr!
More or less making a Social Media notification office decoration (yes I’m a digital marketer what can I say).
Hey Andrew, I would appreciate if you could keep us up to date on your progress related to the JSON sequencing. Especially I would be interested in how you create your JSON data in the first place and how you feed it into the Arduino. Or will you just automatically create this JSON event based (you mentioned facebook)
Will do @Sebastian_Stuecker - one way or another I will have some results in the next 24 hours.
