Now let's arrange the screens in the menu. LiquidScreen welcome_screen(welcome_line1, welcome_line2) / Screen formation from the above lines. LiquidLine welcome_line2(2, 1, oneTwoThree) / Creating a string with an integer variable. LiquidLine welcome_line1(1, 0, "Hello Menu") / Create a string with one string literal. LiquidCrystal lcd(LCD_RS, LCD_E, LCD_D4, LCD_D5, LCD_D6, LCD_D7) example // First, we need to create a LiquidCrystal object. Number indicates which of the attached functions should be called. When a row is selected, one of the attached functions can be called with: void LiquidMenu :: call_function (byte number) To cycle through the lines shown on the screen, use the method: void LiquidMenu::switch_focus(bool forward = true) To call a function attached to a row, the row must have focus (the row has been selected). They are attached using a user-supplied number: bool LiquidLine::attach_function(byte number, void (*function)(void)) Each line has callback functions attached to it (up to 8 by default). Lines of text / numbers shown on the display can be interactive. Screens can be looped back and forth, or a specific screen can be specified by its object or number: void LiquidMenu::next_screen() īool LiquidMenu::change_screen(LiquidScreen &liquidScreen) Menu navigation is done from the LiquidMenu object or, if there are multiple menus, from the LiquidSystem object. I’ll explain what it does, show its specs and share an Arduino project example that you can take and apply to your own projects. This post aims to be a complete guide for Nokia 5110 LCD with Arduino. LiquidSystem(LiquidMenu &liquidMenu1., byte startingMenu = 1) Complete Guide for Nokia 5110 LCD with Arduino. Accepts 0 to 4 LiquidMenu objects and the number of the menu that will be shown first. LiquidMenu(LiquidCrystal &liquidCrystal, LiquidScreen &liquidScreen1., byte startingScreen = 1) Accepts a reference to a LiquidCrystal object, 0 to 4 LiquidScreen objects, and LiquidLine(byte column, byte row, A &variableA.) Includes RGB backlight control, display scrolling, cursor movement, and custom characters all over I2C, SPI, or Serial. An Arduino Library to allow simple control of 16x2 and 20x4 character SerLCDs from SparkFun.
STOCK ARDUINO LCD LIBRARY SERIAL
This structure can be implemented when the object is created or later using public methods of the classes. Library for I2C, SPI, and Serial Communication with SparkFun SerLCD Displays. And, optionally, LiquidMenu objects are part of the LiquidSystem object. The LiquidScreen objects are then part of the LiquidMenu object (s). The LiquidLine objects are then part of the LiquidScreen objects. First, we have the variables / constants that go into the LiquidLine objects. For example, an expansion board with a display and buttons. Input device recommended (buttons, rotary encoder, etc.).Arduino board or compatible microcontroller.LCD display that supports LiquidCrystal (Hitachi HD44780 chipset or compatible).Arduino library LiquidCrystal or similar.It simplifies the menu creation process by abstracting menu items into hierarchically organized classes. The LiquidMenu library wraps the LiquidCrystal Arduino library with the ability to create menus.
