3 Ways to Add Dynamic Icons to Your Displays Using LVGL

[@goldblackbird19]

I watched your previous video a few days ago and was inspired to throw together an ELM327-based boost gauge for my car. I designed a custom needle image but built the dial programmatically bc I haven’t really seen many others do that on here. The difficulties with the docs are real, bear in mind the API changes a lot from v7 to v8 and 9. I decided to go with v9 in the arduino IDE to ease the ELM implementation.

Great to hear. My boards I'm using aren't currently ported to 9 so stuck on 8 until sometime sorts it or I arduously write the port myself

Yes ive been waiting haha!

I worked as fast as possible just for you 😉

Awsome tutorial!!! I want to make a dial-a-boost out of makerfab matouch 1.28 rotary esp32-s3 & to accurate a solenoid. Any suggestions?

[@GarageTinkering]

I LITERALLY just ordered one of those matouch rotary boards in the last hour for an idea I had. I haven't used one yet but we'll have content using one really soon that might help

I am no expert within c but Cant you load the similar icons into an array - like icon green, yellow, red - would be easier when making the update routine?

[@GarageTinkering]

You could group them all like that for sure, probably within an enum. Honestly, right now I'm concentrating on demonstrating the basics, and introducing the mindset of simple problem solving rather than delving too deeply into rigorous best practices. Tutorials will get more complex and deep as time goes on. Just don't want to alienate anyone right now and keep the net of interest wide

I have a couple of the "CYD" boards with display, hopefully it won't be a monster task to work with that? I think it's 380x240, SPI interface, resistance touch screen. Usable to check out this tutorial?

[@GarageTinkering]

Yeah, the CYD boards typically support LVGL though the setup will be probably a little bit different to how I've done it for these. I've just realised I haven't added the repo to the description so I'll do that shortly.

Thx for ⚡ reply! A 🇨🇦 in 🇩🇪

Oh, so much C++, so much code... I'm a simple assembly code guy... Maybe I'm going to be forced to scale back my plans, and dig up what looks like a pretty good BASIC for ESP32 and some STM32 processors and boards... But, I should watch through, to appreciate your weeks of work!!
