Now callback functions get the URI of the request, this allows to use a single resource for multiple different URIs. The is_json flag is now gone for the to-string function, instead the macro has an is_str flag. If set this automagically produces quotes around the string for json output. Now from-string functions can return an error-code, 0 for success, -1 for error.

/*
|
|
* Sample arduino sketch using contiki features.
|
|
* We turn the LED off
|
|
* We allow read the moisture sensor
|
|
* Unfortunately sleeping for long times in loop() isn't currently
|
|
* possible, something turns off the CPU (including PWM outputs) if a
|
|
* Proto-Thread is taking too long. We need to find out how to sleep in
|
|
* a Contiki-compatible way.
|
|
* Note that for a normal arduino sketch you won't have to include any
|
|
* of the contiki-specific files here, the sketch should just work.
