The UART operation is a very complex procedure, no matter which micro-controller you are using. A caveat with this approach is that it only works for flat structures, because the object_class argument really tells the parser what class it should use to deserialise JSON objects in the string instead of Hash (see the similar argument array_class for the analogous operation for JSON arrays). Updated JSONedit: relaxed parser. Use third-party options only as a fallback if you find that class unavailable at runtime. reader. Full support for JSON with UTF-8, including decoding surrogate pairs. No installation required! When parsing a JSON text string a tree is created by linking json_t structures. c you will see the function http_server_init(void).

This can be used, for example, to avoid printing the same static JSON over and over again to The m2m-led. All commands are defined by its patterns eg: "STATus:QUEStionable:EVENt?". If the JSON content is streamed over the network, you need to use a streaming JSON parser. Here first introduce the analysis of JSON format in cJSON; you can see that a character array parsetext is defined in the main function main, which is essentially a JSON string (in the actual stm32 system, it is through the serial port and the communication module Transmission), so when parsing the JSON, you first need to convert it to the format of a JSON Well, the simple part is parsing into maps and lists -- something that every reasonable JSON parser can do just fine.
