Vorstellung: Arduino C++ Menu Lib (ARM oder ESP, ggf auch AVR)

[HaWe]

neues, ganz einfaches Beispiel, nur 1 Menü-Ebene, z.B. auch zum LED ein- und ausschalten:

// TFT Menu 
// (C) 2018 by HaWe

// This example code is in the public domain for private use.
// Use for professional or business purpose: only 
// by personal written permission by the author.

// default TFT: OLED 128x64, compatible to Adafruit (R) Libs
// in this example: using an ESP8266 NodeMCU 1.0 board
// using ButtonClass for button action (up, down, enter, single/double/long press) 

// history:
// 0.0.1  tMenu new list

// simple menu example 
// ver 0.0.1


// I2C
#include <Wire.h>         // Incl I2C comm, but needed for not getting compile error
