STM32和cJSON的问题？我在STM32F429ZI开发板上运行以下代码（项目使用STM32Cube 6.3生成，开发环境为Cube IDE 1.7）：

// Create a json object

cJSON *info;

info=cJSON_CreateObject();

//adding data

cJSON_AddStringToObject(info,"sex","male");

cJSON_AddNumberToObject(info,"age",20);

cJSON_AddStringToObject(info,"name","weijun");

// character pointer

char *jsonStr;

But in the jsonStr only the first two string was added. See bellow:

Name : jsonStr

Details:0x20006e90 "{\n\t\"sex\":\t\"male\",\n\t\"age\":\t"

Default:0x20006e90 "{\n\t\"sex\":\t\"male\",\n\t\"age\":\t"

Decimal:536899216

Hex:0x20006e90

Binary:100000000000000110111010010000

Octal:04000067220
