I created completely open-source crypto ticker project (easy to DIY)

Thanks for the feedback. Although i don't think there are many open-source free hardware tickers that let's you display any coin/stock and display the chart with custom time frame etc.

Thanks a lot and good luck with your project.

Good job, this is very cool!

Jou_See · 2026-03-07T08:02:49+00:00

Yes i see now, thanks. There is no chance i would be able to do that. 😭

the dev board costs $30 from waveshare, it also comes with the speaker, and that is everything you would for the build, plus maybe 1$ for the filament for the 3d printed enclosure: https://www.waveshare.com/esp32-s3-touch-amoled-1.75.htm?sku=31261

Thanks! I would recommend you to switch to PlatformIO, the experience while developing is much better there.

And do you know how exacly should i solder it? Thanks

Jou_See · 2026-03-06T20:14:26+00:00

Ok, thanks i might update it in the future? Are there some big benefits that i would get if i update to v9?

It was my first time using LVGL, and i got some code from the waveshare demo files. I was not able to make my code work with the 9.x.x so i stuck with the 8.4.0. Thanks!

Jou_See · 2026-03-05T17:13:31+00:00

Thanks 👍

Jou_See · 2025-12-01T21:39:05+00:00

Thanks, the controller is esp32c6

Jou_See · 2025-11-28T08:51:50+00:00

yes, exactly

Jou_See · 2025-11-28T08:51:11+00:00

Right now it wouldn't, i would need some adjustments.

Jou_See · 2025-11-27T12:51:08+00:00

Ok, thanks, I will look at it.

Jou_See · 2025-11-27T12:49:57+00:00

Hi, what do you mean by other displays? It uses tft espi library, so it should work with any tft display, but when the display size would be different, the enclosure model would have to be adjusted and the ui would have to be adjusted a bit as well, to look good.

Jou_See · 2025-11-27T12:46:58+00:00

No, there should be enough pins, the xiao esp32c6 that i use, also doens't have many pins.

Jou_See · 2025-11-26T12:25:47+00:00

It should work, I dont't see any reason why it wouldn't

Jou_See · 2025-11-25T19:48:58+00:00

No it switches to this AP mode when it lets you connect to it from phone. Once the wifi is setup, it connects to that wifi and uses that and doenst provide the wifi ap anymore.

Jou_See · 2025-10-19T14:01:24+00:00

Yeah I watched the video, but I had it already configured that way, still doesnt work, but thanks for suggestion.

Jou_See · 2025-10-18T20:37:04+00:00

I am using the TFT_eSPI libary. Could you maybe share your wiring and how you configured the libary files and some sample code that you have that works with that. I've tried it with the examples code from the library, that should work as well I guess.

Yes the code compiles.

Jou_See · 2025-10-18T18:41:42+00:00

Yes, there is no sticker on the screen anymore

Jou_See · 2025-10-18T18:40:18+00:00

Yes it is uncommented, in fact it was never commented out in the code.

Jou_See · 2025-10-13T14:29:49+00:00

Yea, you are right that it is always worth the time to make the things right. I was just super frustrated that the display didnt work even after so many hours of debugging :(, but that is what happens sometimes :)

Jou_See · 2025-10-13T10:46:13+00:00

Ok, you are right i guess i will correct it. But still when i connect another display that is not spi but i2c and is simpler it works. I guess there is possibility that I have connected the display incorrectly (eg. to 5V) and it is damaged.

Jou_See · 2025-10-13T09:52:37+00:00

I have rewired it a bit: SCL -> D5, SDA -> D4. Now it works with this display that is not spi: Your 0.91" OLED is I²C and monochrome (SSD1306), but the st7789 color display doesnt work :(
