Use a wire link instead if you do not have a push button switch. The image below shows examples of this type of switch. When the switch is released, the contacts open. Momentary means that the switch stays closed only while pushed. Also works on for you to fiddle with.A push button switch called a momentary push button switch is used in this tutorial. While ( analogRead(keypad_pin) >lcd.print(F("TEXT")) << method, it works really well. If (btn_push = 'S') //enter selected menu Int keypad_pin = A0 //analoge A0 to sense button values. Int poz = 0 // cursor position on actual page * The last thing I did before posting was to relaod and test this sketch, so it works. * The original sketch is from: Stanislav Petrek of Slovakia, you can find sketch on YouTube comments. * that there is a limit to how many levels you can have, how many do you really need. * look at the last 2 -page()- sections for instruction on extending down even further, I don't think * I believe that I have removed all unnecessary script, but I may have missed some. * buttons are less picky than rotary encoders, even the good ones, just my experience. * I believe Slovakian, that was fun, stripped down and modified for button control, I have found that * I am using an I2C LCD2004, but any display will work with minor mods. * This is a bare bones menu using buttons to navigate and select, there are no special libraries, instructions at the bottom of the sketch. I have just tested this before posting, so if you don't get it to work, check your wiring. Here is a simple, fool proof button menu, that i think has NO limit in depth. Ok.nobody bought into this and I understand why.menus have been done to death, but not being one to quite I have answered my own question. If(levelMenuPage != levelMenuPageOld) //only update display when page change If(mainMenuPage != mainMenuPageOld) //only update display when page change If((btn_push = 'S')&(menu2 = true))//enter selected menu If((btn_push = 'S')&(menu2 = false))//enter selected menu Lcd.begin(20, 4) //Initialize a 2x16 type LCD LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE) // Set the LCD I2C address It's layed out long hand, I'll neaten the code up after its working.Ĭould you pls have a look and see if you can access level 3.Īlso if there is an alternative for multi level menus, happy to look at those also, just after something that works, have tried dozens that i have found on the web.either no sketch with the video(how i hate that) or sketch just doesn't work period.ĭescription : Simple Menu function on LCD Have been working on a Button Menu for a while now and can't break thru to the 3rd level, which in theory would give access to levels 4/5/6/etc.
