Your Tft_espi tutorials are fantastic. Thank you so much for taking your time to share this great information. Matt.

Excellent video! Your English is not clumsy at all. You are a very clear presenter and every video I have watched has been an excellent presentation. Large parts of America have both English and Spanish as primary languages so your English closely follows the normal English of somebody who speaks multiple languages. Most importantly, you explain everything very clearly. Excellent channel!

Thank you Louis, I will try.

Cool stuff, I like your Video Tutorials, and they help me much to get run things I don't had a clue about. My main problem was to get run my new display with tft eSPI, about there was not much Info around how to do with my display. But I find out how, and got it running. Since then i can play around with your nice tutorials! The Idea to use eSPI i got in your videos, and it made my display much faster, as the original library does from my display.

Brilliant. Thank you so much for taking the time to share this with us. Much appreciated

Thanks for this tutorial. I really like that you upload and show after every step so we can truly follow along.

Thank you Volos, I have been fighting with trying to get transparencies to work for a month now, your the best. Regards to family.

Your videos are exactly what I need to make some additional gauges in my SUV as I have changed to a different power train. Many vehicle functions were handled by the old engine controller, like the air conditioning compressor logic and I am adding functions like variable speed electric fans as well as additional gauges. I am using Arduino mega2560 A/D to read a lot of sensors, scale data and provide basic control logic. Then the scaled data is going to the LILYGO T-Display-S3 via. I2C to drive multiple gauges. Your examples have been very instructive and with them my code is really improving - Thank You

I've been searching for a way to get rid of the flickering, even been in the official lilygo forum (and in the TFT forum) and not anyone could give a clue... finally I found this video with a simple hack, thank you so much 😊😊

You are doing a great job with English language. And this is an interesting concept. I now know how to eliminate flicker and draw sprites. Very nice. I'm sure it probably took a while to figure these tricks out. But it looks very nice.

Thank you for your clear explanation. I learn so much from every video. I think the videos are much better unscripted because we get to understand your thought-processes, and what you say is more authentic and natural.

Como siempre, los mejores códigos y ejemplos. Gracias, profesor.

Thanks! Very informative, like this whole series. Very clearly explained. (And your English is perfectly fine for anyone who actually cares to listen and learn -- and if they *don't*, forget 'em and carry on!).

Thank you. It was helpful to see how some of this comes together.

I finally got it working. I am using a LilyGO T-Display S3 and there are some small variations in how to put the code in. But the code works. Thank you! :)

Great video, i suggest you to also talk about the approach used in some examples for the moving sprites of the tft library. They use a buffer to “clear” the background as far as i understood.

Learning quite a lot watching your videos. Keep up the great work!

Sprites on a ESP32... Since long time I try to understand what you tell us now. But not had a clue before. How crazy is this solution, to put the graphic in a sprite and this graphic in another sprite to stop flickering. .... but finally it makes sense, and it does what you want. Have to see the video more times to really understand this technic. I definitely will use it in one of my projects in the future...

Very useful video and very well explained...step by step . Perhaps you should mention in one of your sprite videos . that the MAIN TRICK with SPRITES is, that you are drawing directly on a " screen buffer " in your MCUs memory !!! You dont draw on the TFT using library functions , which is much more time-consuming. When your IMAGE in your SCREEN BUFFER is complete you push it out in one piece to the TFT. This can even be done still faster by using DMA - direct memory access. Each frame is drawn on a clean sheet of paper ( the background sprite ) so you dont have to take care of the old graphical content. Years ago - without sprites - it was very complex to draw moving graphics , because .... before drawing new content you always had to "neutralize" the old content . Thanks a lot for your videos - because you wont find these excellent explanations on any other place .

Excellent video!

FANTASTIC!

Amazing, man. When I saw you using RGB565 2bytes here, I tried an icon too and now it's working. Probably I did some mistake before. But I need to confess that image used in example sketch from LilyGo let me crazy. I can't understand the array of 1 byte to generate rgb565.

This was great! Thank you!

Very well explained

Nice gadget, I have to think about it how to use it in my projects!😀

TFT_eSPI library is amazing but the documentation is not that extensive. It is difficult to figure out how many amazing things we can do. But thanks to your tutorial, i can understand much more things in details.

Excellent video whip is wonderfully explained, and your English is a million times better than my Russian😂.

I think this is the best video about this topic. Really really impressed how straight-forward it was. Do you know if it is possible to create gradient transparency? One side of the image fully transparrent and the other no transparency. Useful to create shadow effects. Thank you for the awesome knowledge and content!

Excellent content

Your English is very good and some of your technical language is better than those who are English. You only seem to get confused with some of the pronunciation and that will be because words are pronounced differently in different parts of the world. Keep up the great work.

A quick tip on using Paint: You don't have to resize the image if you paste it in then hit 'Crop' while it's still selected.

Good video. Good explanations.

This is an excellent video! The way you explain and demo things makes things so easy to follow and logical. Thanks for that. Just a note. In your video, you mentioned that links that you use, like the rinkydink one, for example, will be in the description. Other than links to other videos and the main code link, I'm not seeing any other links. I'm just now about to get started with ESP32 as I kind of want to move up from Arduino stuff, so any links and suggestions are always helpful. As I've not yet connected my 2, ESP32 boards to Arduino IDE (which I'll use), I'm not yet sure how to find/install whatever board drivers are required. LOL Thanks in advance.

The technique to avoid flickering using "background" sprite is called "double buffering" 😊

Hello Volos, I love your videos. I bought my self a TTGO S3 T-Display. I could manage to get it working with arduino IDE. But not with PlatformIDE. Can you give me a hint, where to look, to get PlatformIO working with this nice Display? (After upload it always stays black) Another question, how do you design your pixel screens ? I'm sure there are some kind of UI designer out there.

Thank you for you work. I have question how do when arrow move very fast(full speed) and can regulate the speed?

Is there a reason to use two sprites vs just pushing the arrow image to the background sprite? What is the purpose of making an arrow sprite to begin with? Thank you!

I forgot to ask, are these sprite things dependent on the display type, make, model? Or will they work on any display, even like an ST7735 models? (1.8" and 0.96") ??

Nice info Volos, but help. Sprite is erasing background as it moves, either alone or inside another sprite, any ideas?

Thnx. I just can’t realize why you fillScreen inside loop, that’s cpu expensive. Sprites aren’t like real full-managed-moving sprites? In worst case, is possible to create 2 (or whatever) sprites to be used as save-restore background sections? (excuse my eng)

Good

Great tutorial. I learned something new, as always with your tutorials. But, a problem. When I code: txtSprite.setSwapBytes(true); txtSprite.setTextColor(TFT_RED, TFT_BLACK); I get blue text. All colors except white are wrong, too. Even if I leave out the SwapByte, the colors are still wrong. Any idea why? I am using a T-Display S3.

New to PCB - thinking of doing one that can play an animated gif on loop with sound speaker, on off switch, rechargeable battery and led strip light. Would you know how to do that? There's not a lot of resources out there. Thank you

i am trying to display a jpg or png but it is rendering very slow with about 160 - 300ms per image. the image is stored on the esp32 using littlefs. is there a way to speed that up? i have tried normal tft and sprites.

Question for anyone. If I have multiple sprites. How do I control their front to back order. So when they cross on the screen. I control which sprite will be on top.

Hello Volo, I have one question about transparent sprites. Is there a way to send you an email. In short, I created an yellow Circle in a Sprite and it is displayed in Purple in Background Sprite.

Hi Volos, as a very beginner in MCUs, I was inspired by your videos. Now, getting to an intermediate level, I implemented a simplified version of Wolfenstein 3D in ESP32. Please find it on my channel.

Volos - thank you for moving the needle on the UI - very good presentation. I bought 4 of these lilygo S3 and can’t get any to display, the code is running, no display, my money is on tft_eSPI - even though I did on PC and Mac. I’m only using the Arduino IDE. I’m a notepad++ guy 😊- No VSCode yet… any ideas? All the boards worked with “factory” code.
