Thanks for this excellent tutorial. I purchased the display and downloaded your project. I'm using platformIO so I made the necessary tweaks to get it to compile. At first I had issues with it only displaying the orange screen. I finally got it to work by adding the line: img.setColorDepth(8); right before img.createSprite(240, 240); It seems to be working fine now but I'm not sure why I needed to do that? The image file is using 16 bits per pixel it seems. Color looks right though. Anyway, a heads up if someone else is running into trouble. Thanks again!
@Wolfe032 thank you for the solution. I had the same problem and spent my time to check settings in libs. I had 7 pin version of the round display- without lcd underlight pin. Did you find the explanation the problem? Have you tried any different libraries?
I had the same results with this code and the Volos's Smart watch code using the Arduino IDE and PlatformIO. Your img.setColorDepth(8) worked here but not on the Smart Watch. I pre-calculated all the static arrays in the setup loop and stored them in program memory freeing 6K of ram in this code and 9K in the Smart Watch. Both work afterwards. I'm guessing that a large sprite requires a lot of ram.
Thank you for fix. I have been tearing my few remaining strands of hair trying to understand why I had an orange/yellow display. @Volos - would you please consider updating the code or adding a text comment to the repository?
Sir my respect, you have left me speechless, I only can say you are amazing!. Thank you for sharing your immense knowledge and experience. I am very grateful, Thank you very much!.
Great video! :) Not stellar walkthrough of the code, but it does not matter! You covered how things work and saved anyone who want to use the display a lot of time! So thank you so much! :D
An extra tip; If you're using only one SPI device, you can connect RST to VCC(or NRST), and CS to GND. That's the easiest(less wires) way to connect a display, requiring only 3 wires and power. You'd only need to connect CS to an I/O pin if you're sharing the SPI bus.
Great video and project. 👍Like Wolfe032 mentioned in a previous post, I had to add the line: img.setColorDepth(8); right before img.createSprite(240, 240); in the setup routine to get it to work for me. Now I'll have to figure out how to use different input pins for each separate gauge.
Yes, very impressive display, layout and response time. The TFT_eSPI examples also give some guidance on the coding approach. The details for working with sprites isnt easy, but looks like it is worth persevering to get best performance.
Sorry if I missed this in the video, how does the pixel layout work? is it like a square but only the existing pixels get displayed? or do you need to structure your data array with each line being progressively longer as you approach the equator and then shorter as you approach the bottom?
I just get an orange display, the arduino examples for the TFT library work fine, I am not clever enough to know why it does not work, I have connected the inputs switch and pot to ground, but really interesting project.
How are images like this gauge even made? I don’t even know what it call an image like that to look it up, lol I’m new to this but I learn pretty quickly. How does someone go about designing something like that gauge? In what kind of program? A video that covers that would be really helpful as I have lent really any so far, or maybe I’m not looking in the right place?
That was a great demo, you absolutely do not need to apologize for anything. Thanks for sharing. If you ever get a chance to work with the ZX2D10GE01R-V4848 round display, I'd love to see your ideas.

Hello, I am trying to use this sketch. Unfortunately the image and the pointer is not displayed. I use a round display with GC9A01 driver without LED and a ESP32 -WROMM 32 controller . Is there a newer version of this sketch ?? Greetings
I've always wanted to do a watch project, I think this display might just do the trick. I'd love to make it self-contained, but I couldn't use a full-blown ESP32 demo board, I'd have to use something much smaller. I didn't even know these displays existed, so props for that!
Very good. One question: all gauges include files (.h) are arrays of the converted images. Any chance to have the original images so we can modify them?
nicei work. I recommend something to cover the screen from sunlight, I've done a similar project before but facing with sunlight and display brightness is a pain on the neck. I cant saw most of the details I put effort on HMI. so I think the best always is custom 7 segment dashes, you can always make them enought bright to see it at daylight.
My IDE kept throwing up a serial comms error when trying to upload unless I unplugged the display. I suspect it's a serial comms pin use thing like Rx0 and TX0 on Arduinos.
That looks great! id love to do something similar using 2 slightly larger screens (4" square) to run RPM and Speed based on inputs from my car. Any advice on achieving this?
Thanks for all your videos, if I want to get started with ESP32 programming, which one would you advise me to buy please, I saw that the ESP32 C6 I think was the model, but I didn't understand some people say there aren't enough compatible libraries?
I have one of those cheap Chinese smart watches that broke. I'm going to try your code on the screen. It's a round screen and I have some great ideas for it if I can use it. Thanks for the ideas in the code.
I have searched the net for a solution but can not find, this is the closest i can find, i have a gc9a01, an esp 8266 and a rotary encoder (KY040) a nema 17 stepper motor and a A4988 to drive that motor, is it possible to drive that motor and show the degrees in the display when i turn the rotary encoder?
I tried your code and at first I couldn't get it to work. All I got was an orange screen (TFT_ORANGE). After an hour of debugging I think my ESP32 was getting out of memory by the while(a!=44) loop. I then enabled the PSRAM on my board and it started working (although with a lot of flicker, but stil it works). So it's possible this won't work on boards without PSRAM. Great video!

@@MegaScott So where is this memory? I expect it is on the LCD driver chip for fast access? Also, I think this is a sprite size limit not a memory limit.
