Thanks Antony, and thanks for coffees. 😀

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.

Excellent! I would love to see a speedometer project using this display and small GPS module NMEA input !

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!

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.

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.

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!

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.

“…TX Dva” 😊 Awesome work as always

Cool project :-) I'll adopt this to use the D1 mini and re-generate the image files to match BMW orange 🙂

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 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!

Hello, i need Help for The tft display 40x160 (160x40) - DRIVER: GC9D01 - i need a Grafic-Programm with esp32 - Thanks

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.

Nice! Thanks for sharing this., your explanation is ok.

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?

If I want to use a 720x720 display can I take the esp 32?

This is amazing. I'm not familiar with coding and electronics. But I would like to create digital gauges for classic Muscle Cars. For example, I have a 68 Chevelle and a 65 Impala. And planning to modernize them with newer engines that uses fuel injection and computer modules. OBD Link, and use the computer data to send to a monitor like an Android or Ipad set up. But would like to use the original Dashboard space where the gauges are and use digital displays. I'm going to be researching about this. Thank you.

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

Could this be setup to show multiple sensor readouts in numerical form instead of a needle gauge?

Can gauges be made to react from an incoming PWM signal (such as from an RC receiver).

can you make a smartwatch step by step

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?
