//500ms调用一次下面的代码没过多久就出现了上面的打印 trainingData_t wdata; //结构体大小为20字节 itoa(globleTimeStamp,string,10); wdata.startStamp = globleTimeStamp; wdata.jumpCount = j; wdata.jumpTime = j++; makeHistoryTest(string,(char*)&wdata,sizeof(trainingData_t));

void makeHistoryTest(const char *key,void *value,uint16_t valueLength) { struct fdb_blob blob; fdb_kv_set_blob(&kvdb, key, fdb_blob_make(&blob, value, valueLength)); rt_kprintf("key:%s\n", key); } 我的需求是每秒存入sizeof(trainingData_t) 大小的数据，key取四字节的UNIX时间戳，value就是这个结构体数据。请大神指导一下，谢谢

我也遇到这个问题了，请问你解决了么？
