I wrote a little program: int counter; int number; char text; StaticJsonBuffer<200> jsonBuffer; JsonObject& root = jsonBuffer. Thanks. The book also contains a quick C++ course to catch up with memory management in general. It dissects StaticJsonBuffer and DynamicJsonBuffer, shows the differences between the two, and tells how to choose between them.
