Refactoring EPS32NVS library to Preferences library

[arcao]

• Renaming all set* functions to put
• Added functions for float, double and bool

Test code:

#include <Preferences.h> Preferences preferences; void setup() { Serial.begin(115200); Serial.println(); preferences.begin("my-app", false); preferences.clear(); preferences.putChar("char", -8); preferences.putUChar("uchar", 8); preferences.putShort("short", -16); preferences.putUShort("ushort", 16); preferences.putInt("int", -32); preferences.putUInt("uint", 32); preferences.putLong("long", -32); preferences.putULong("ulong", 32); preferences.putLong64("int64_t", -64); preferences.putULong64("uint64_t", 64); preferences.putFloat("float", 12.34); preferences.putDouble("double", 12.34); preferences.putBool("bool", true); preferences.putString("char*", "char*"); preferences.putString("String", String("String")); Serial.println(preferences.getChar("char")); Serial.println(preferences.getUChar("uchar")); Serial.println(preferences.getShort("short")); Serial.println(preferences.getUShort("ushort")); Serial.println(preferences.getInt("int")); Serial.println(preferences.getUInt("uint")); Serial.println(preferences.getLong("long")); Serial.println(preferences.getULong("ulong")); Serial.println((long int)preferences.getLong64("int64_t")); Serial.println((unsigned long int)preferences.getULong64("uint64_t")); Serial.println(preferences.getFloat("float")); Serial.println(preferences.getDouble("double")); Serial.println(preferences.getBool("bool")); Serial.println(preferences.getString("char*", "")); Serial.println(preferences.getString("String", String())); // Close the Preferences preferences.end(); } void loop() {}
