If you have a Teensy project that uses TFT displays with the either the ILI9341_t3 or the Adafruit_ILI9341 drivers, you may need some menu code. If you want to drive your menus with touch screen or mechanical buttons or encoders, this is the perfect library for you. This FREE code library will simplify creating and implementing a menu systems for microcontrollers and TFT displays such as the Teensy and ILI9341_t3 library or ESP32 and the Adafruit_9341 driver. This library includes two menu objects where you can use either or both:
1. A simple selection menu (ItemMenu) where the user can scroll up/down and select an item and some programmer defined action can be performed such as drawing a screen or activating a sub menu
2. A menu with in-line menu (EditMenu) where the user can scroll up/down the list and select an item however the difference is that move/up down on a selected item will scroll the values stored with that menu item and NOT scroll the list, selecting a selected item will restore control to moving up/down the menu list

Dear sir, thanks for providing such a wonderful tutorial. I learn lot of things from your videos. I make a project with Esp32 tft display and add a function to control led on off using menu and it perfectly works. You have such a great knowledge. I am very happy. ❤❤❤❤

@garyblackwood9459 9 дней назад

I must admit this looks really great, just what I was looking for. I had started on a simple settings menu of my own but it is just that very simple at the moment. Like you I used a list of objects each one specifying type, min, max values and increment plus a callback method to set the current value so its new value can be set while it is being changed and then on exit you decide to keep the new value or go back to the original value. I will try out your excellent library as it does so much more and no point in reinventing the wheel, thanks for sharing.

Sir, Is you used built in SPI pin?

@nomlas0803 Год назад

Nicely done! How do you suggest handling free text input, like SSID, password, etc? Using encoder to spin through the alphabet would be good enough for infrequently changed fields.

@KrisKasprzak Год назад

Thanks! One of the touch libraries has a keypad example for touch screens. while it only supports 0-9 as input I can see how this concept could be used to emulate a keyboard for keystroke input.

@carlosbarberis49 2 года назад

Although I think these menus you created are great, I don't see anyway to specify the SPI control signals for the ILI9341 TFT display as well as touch screen that comes with that display. I'm I missing something here? Thank you.

@KrisKasprzak 2 года назад

you pass in the display object so the lib can draw stuff. You use what ever touch lib you prefer and process touch accordingly.

@ThermaLTake94 Год назад

Greetings from greece kris!! what an awesome library,im using an esp32 with the tft_eSPI library,can i incorporate your library with what i already use?

@KrisKasprzak Год назад

You definitely will not be able to use this library directly. I took a quick look at the class definition and it’s very similar to the library I’m using. give me a week or so and I’ll see what it would take to port this over.

@user-ku5hi8ge6u 7 месяцев назад

Came across this and this looks to be exactly what i am looking to incorporate into my project. Will admit, I am very new to this space. My challenge so far is finding a capacitive touchscreen less than 3 inches. I found one on amazon that uses the ili9341v driver. I see your repo mentions ili9341_t3. Do you think there will be any compatibility issues? Curious what screen you are using in your video.

@KrisKasprzak 7 месяцев назад

If ili9341v uses the Adafrut_GFX library, my library can be adapted with around 10 lines of code changes. If the ili9341v does not use the Adafruit_GFX, this lib can't be used. I generally use displays like this www.amazon.com/DIANN-ILI9341-Display-320x240-Screen/dp/B0BNQBKFCT/ref=sr_1_4?crid=2KCRYW9FBAXRC&keywords=2.8%22%2BTFT&qid=1702491153&sprefix=2.8%2Btft%2Caps%2C81&sr=8-4&th=1 Also if you are using Arduinos, this lib will most likely not work--memory or other issues. I user Teensy 95% of the time ESP32 the other

Hello; I'm working a 3.5 inch TFT with ILI 9488 as driver; how can I make the touch screen work with it and which library should I use?

@KrisKasprzak Год назад

What MCU are you using? This library could be easily adapted to work with other libraries provided they are based on the adafruit_GFX library. The read me posted on the kid hub page has a note on what he would need to edit.

@connalmcilwraith4367 Год назад

Hi - I think your menu looks fantastic and I'm really keen to incorporate it in my project. I am using an ESP32 and an rotary encoder and, according to your Git Hub page, your touch sensor for ESP32 should allow me to switch off the touch screen and use a mechanical input instead. However, I can't see any code for an encoder. Am I missing something? Keep up the good work, though!

Hi - I've found one issue (not with your code) but I need to use a different screen driver, specifically tft_eSPI, as all my colours are inverted. However, if I do use the new driver, the compile stalls at the fonts because the eSPI driver expect the font in a different format. The menu.init in Adafruit_ILI9341_Menu.h is expecting 'setFont' and eSPI is expect 'setFreeFont' (I think). I've tried changing this (and many other pemutations) but I haven't had any success yet. Any suggestions? Thanks

I have a TEENSY 3.2 with an Adafruit 2.8 TFT SPI Cap touch. I used your Pin defines but it won't compile I tried with a 4.1 teensy ; no joy. The teensy works with the display with Teensy 3.2 with simple sketch but no cap touch. I'm following the pin defines in the sketch. Getting close but no joy. I think it's the libraries that are killing things. Retrying on different computer!

@KrisKasprzak Год назад

Yikes I don't think the lib here will work with cap touch devices--different chip i'm sure.

Yes I am just getting started with Arduino. Have a lot to learn at 75 years old. I have nothing but Arduinos from Nanos to Megas. Can I use this for Mega 2560? Is there a script available that I can look at and learn a lot from it? Thank you!

@KrisKasprzak Год назад

You can use this with a Mega2560, just make sure you use the Adafruit_ILI9341 display libraries and my Adafruit_ILI9341_Menu library. There are examples in both libs that can help you get started. I'd recommend getting the display working first

@KrisKasprzak Год назад

I have updated the library to allow touch AND mechanical input. You can press menu items, then use something like and encoder to scroll through values. I have added an example for using Touch and and Encoder, noting that since you are having to trap encoder and touch, there is more processing code. Fortunately I was able to get both working w/o any method changes so this version should re-compile without errors. I have done a fair amount of testing, but if you see any issues, let me know. github.com/KrisKasprzak/ILI9341_t3_Menu Have fun..
