Thank you for very pedagogical and informative videos! If you want to increase the frame rate of the larger screen only update the sections that need to, do not push the background, unless it has changed. Encapsulate the different elements. For instance write the label, number and rectangle of income to a small sprite and then push that to the screen. you probably double the frame rate doing that. if you take it one step further you can draw antialiasing rectangles once (in background step) and just use a smaller square to update the different elements. this way you gain two things, organization and performance.
Thanks for this great introduction to T4 display. I managed to cancel my T3-S3 Touch order and will order this instead. You are a great Lilygo ambassador! 🎉
Small tip: As the polarity of Lipo are reverse you can just swap the pins in the JST connector (remove them carefully). Much easier than resolder new cables.
The timing was off releasing this board! I just received the smaller board a couple of days ago but I'm already wanting this bigger unit. Your video featuring the attitude sensor is my current interest. That graphic sized to fit this board would be practical to view in an experimental aircraft. Another practical application for homebuilt aircraft would be to make a compass display with the ability to enter compass deviation values to correct for shifting magnetic poles. That's a very basic gauge to have in small aircraft.
That looks amazing! Thanks for covering this. The on of switch is incredibly useful and i have to manually add them for my t display s3. Now i want one! I also need to find a waterproof version for my swimming laps counter! I can 3d print a case but probably silicone to add more waterproofing

This guy knows how to make a nice UI. How in the world do you mount this in a real application? I think so many of these boards just seem to be for tinkering, but not a real application.
they can be used evrywhere, and they are used evrywhare, on 3dprinters , laser engravers, i helped even woth coffe machines that uses thease screens, i helped with few of them ended in racing cars, planes..... posibilities are endles.
@@VolosProjects Understood that they can be used for one off projects and I have used them for my own projects, but most don't seem to be manufactured for the mass market. I'm mainly focusing my comment on the all-in-one board/screen combo. The device your showing has no mounting options from what I can see. So how do you mount it?
@@larrybud i can see your point, yes they are to expensive to mass production devices. It is realy easy to mount in panel, i will show that very soon. But i agrree with you most of boards are hard to mount.
Thank you! That looks like it'd be great to combine with Home Assistant. I'm putting up cameras, and planning to add other sensors and Home Assistant is a nice open source solution that can tie a bunch of things together. Wonder if you might be able to write a dashboard for that device? Yes,. after some quick searching I see someone created a "responsive design" for it, which should fit nicely with the smaller screen. Also there's an "ESPHome" project, merging the Home Assistant with the ESP32. Thanks again!
I am intrigued by the latest and greatest esp32 displays. Has anyone seen any power usage estimates for using a battery to power this product? I can't seem to find any yet. Thank you for this presentation!
I got my T4 S3 display about a week ago. I got this one after I had a good experience with their T-Display S3 AMOLED Touch display but found the 1.91-inch display a little too small. I use Squareline Studio for designing the UI and I have a smooth workflow for this. Both boards are up and running as displays for a model airplane weighing and C-of-G scale. The displays on both these AMOLED boards are very beautiful. The only manufacturing defect I have noticed on my T4 S3 that the screen bezel was glued on the screen slightly askew. But it is only noticeable if I draw a thin border on the display or have lines drawn close to the edges of the screen. The smaller display also had a defect where the screen would flicker if pressure was put on one corner of the screen. But after fiddling with the connector ribbon between the board and screen, the problem never happened again.
Wow, I used your link to try to purchase this screen. The site shows this item as sold out. I have sent an email to the company to find out if they anticipate obtaining any more.
Pretty cool display I like it , a bit expensive compared with free apps and every one has a Smart phone that's what makes it expensive you would want to make a reasonable profit too.
excellent project, I really liked your work, it is priceless, I really want to see the connection to T4s3 of some modules like GPS compass and BMP280 accelerometer gyroscope, some interesting solutions using LVGL like and subscribe definitely. and if there is a video with the connection of the above-described modules or others to various GPIOs and how it is organized in the code. I'll be waiting for new videos on T4-S3. Thank you.❤
like always, i design them on paper or in some software and then i write bunch drawing functions. there is many reuploads, and many hours of trying colors, fonts and positionsing.
Beautiful display, great video! Thank you. What is the part number for this display ? We may want to make a project for this display that needs a custom PCB design.
Volos, love your designs! I have a question that hopefully you can answer, is it possible to run a local webserver or browser on these with webkit so it would be easier to design the interfaces so those of us without the cpp knowledge like you have are able to make intriguing designs for this? For someone like myself using a html/css/php/javascript stack would be amazing..
I think we need more something like stm32 primer2 style devices. touch display + mcu + debugger + battery and gpio header inside with nice handheld case.
Wow, these seem really cool. I really want one of these(or the T-Deck from Lilygo as well) to port Linux to. There already is Linux for the ESP32 S3, and I think I could create drivers for the display etc. relatively easily. Just couldn't buy the hardware yet :(
No, this is a MCU not a SoC. It's like putting android on a Gameboy Color. It won't work. Nice idea though. You could still use this to make a simple MP3 player.
how to program such beautiful graphics? it's hard to program display by code. or you have special graphical base software tools for the graphics vector / sketch programming.
it would be cool to see something like this be used for a assistant chat bot with animated avatar and text to speech connected to a llm running on a local computer
I love your videos. Learned a lot from it about using displays with these mcu's. Do you know any way with these displays to show images that are not in the same resolution as the display? (mostly to scale down jpg images to the resolution of the display). I use the TFT_eSPI.h and the TJpg_Decoder.h library but it seems to only have a way of scaling down in steps of 2, 4 or 8 and for most images that will crop a lot of the images off screen. Perhaps if there is a way you can make a video about this if you are going to use this display as a photoframe...
I'm super excited about the boards lillygo has been making but for me, $50 is too much for an esp32 based device. I would love to have this square formfactor with a cheaper display.
i started to use sqare line few days ago, and i stil havenet posted video about it, all my projects are designed with pure code and tft_espi library, and lots of reuploading :)
Already with the amoled S3 I struggle so much with having enough memory for a framebuffer. This T4 is cool but having a controller with a bit more memory would really be nice.
A suggestion? Perhaps include physical mounting style/options in the videos. Many boards have great feature set, only to find they are nearly impossible to actually mount in a professional looking way because of the horrible placement of mounting holes, holes without access etc etc. Nothing less pro. looking than having to hot glue a board into place.
The video you made last year for the smaller board used Nick's driver solution to make it easier to use. Do you no longer need his solution going forward with these new libraries?
@@VolosProjectsIt's modern AND low-level which is rare to have both for new languages. It doesn't have all the C(++) clunky mistakes from the 80's and 90's
Holy crap! That is just shy of VGA! You could run a DOS emulator and use that like an old PC. Actually, get on that Volos! Run some PC software like Wolfenstein and Doom on that chip! Not only would that run DOS, but it would be better spec-ed then any Laptop sold around 2001!
