keyvalues

This is an Arduino library for storing Key/Values in RAM.

See the examples to see how it works.

This Library uses TVEC Template Class from Embedis project (https://github.com/thingSoC/embedis/)

abstractKV

The class abstractKV implements a template class for use with different types of values.

KVString

This class implements a class with value of type String

KVlong

This class implements a class with value of type long

How to use it

• putting a key/value: objectname.put(keyname, value)
• obtaining a value: objectname.get(keyname, value variable)
• obtaining the number of keys/values: objectname,.size()
• deleting a key/value: objectname.remove(keyname)

The abstractKV implements methods for get/put/delete values in the list.

Simple example:

#include "kvstring.h"

KVString kvs;
String value;

void setup() {
  Serial.begin(9600);
  kvs.put("key", "value");
  kvs.get("key", value);
  Serial.print("key=");
  Serial.println(value);
}

void loop() {}

Examples:

• simpleKV - The above example
• progmemKV - More complex example - uses PROGMEM for the source of the values
• persistentKV - dumps KVs to EEPROM and loads them. This example requires CRC16 library,
