The menu is easy to edit and adapt for various projects.Dear friends welcome to another tutorial!

At the top of the sketch screenshot is a tree-like structure which, when compiled and the final output "root" of the tree is routed to the menu-controller input that accepts it, will automatically generate a navigable menu just as pictured in the graphical designer. When pressing SELECT, the LCD is cleared.

The value stored in the buffer is displayed on the first line of the LCD.
Four-line displays are supported by the menu controller node but the leaf-type menu interface with four lines of text input hasn't been written, yet.

I have used To connect the LCD display to the Arduino I first soldered two 6-pin strips male on the proto pcb and then, thanks to the an idea given to me by Emanuel in the comments of another post, I used an old parallel cable for IDE hard disks.Update: As noted by Liudr for safety reasons is better to use a very old 40 wires calble instead of the 80 wires cable used by me in these pictures.I think this type of structure although very simple may be useful in many situations to manage menu and LCD display with Arduino, and ican be used as a basis for other modifications.This program is free software: you can redistribute it and/or modifyThis program is distributed in the hope that it will be useful,You should have received a copy of the GNU General Public Licenseconst int buttonPinLeft = 8;      // pin for the Up buttonint lastButtonEnterState = LOW;   // the previous reading from the Enter input pinlong lastEnterDebounceTime = 0;  // the last time the output pin was toggledreadButtons();  //I splitted button reading and navigation in two procedures becauseMenuItem newMenuItem=changed.to; //get the destination menulcd.setCursor(0,1); //set the start position for lcd printing to the second row// check to see if you just pressed the enter button// If the switch changed, due to noise or pressing:if ((millis() – lastEnterDebounceTime) > debounceDelay) {// check to see if you just pressed the Down button// If the switch changed, due to noise or pressing:if ((millis() – lastEscDebounceTime) > debounceDelay) {// check to see if you just pressed the Down button// If the switch changed, due to noise or pressing:if ((millis() – lastRightDebounceTime) > debounceDelay) {// check to see if you just pressed the Down button// If the switch changed, due to noise or pressing:if ((millis() – lastLeftDebounceTime) > debounceDelay) {lastButtonPushed=0; //reset the lastButtonPushed variableUtilizzando il sito, accetti l'utilizzo dei cookie da parte nostra.

Continuing work on reducing the RAM overhead, perhaps by using more compile-time metaprogramming and storing as much data in Flash memory rather than interconnecting/concatenating the tree components at run-time.This second example sketch screenshot shows how to use the menu controller to take an external or internal value as input to the controller, display the current and previous values on a desired menu page, and select a new value and store it to a buffer.On the right the menu-controller node is being fed with the output of a counter, fed by a "clock" node. The goal of this project was to use the XOD graphical programming environment to provide the ability to rapidly prototype menu-driven interfaces for Arduino-compatible microcontroller projects using a drag-and-drop/WYSIWYG style of interface.
