That's interesting. Thank you for good information. I’ll try it.

But Instead of ili9488 wouldn't be ili9341 preferred as it has more stable libraries if working on arduino projects?

@@advaitkulkarni8929 I prefer ILI9488 to ILI9341. The reason is that it can use DMA. However, in this video, only the 3.5-inch display is compared.

They all have the same source code, only the graphics driver has been changed. I think my LVGL projects can teach you how to do GUI work. ukposts.info/slow/PLnq7JUnBumAzjd7Nz6O6fIegE49LAMBFv

@@ThatProject Thank you.

Unfortunately, I haven't had a chance to do a project with STM32. I'm sorry I couldn't help you.

@@ThatProject thank you for the reply. I converted a old dirtbike to efi and want to dona digital dash that read the data stream from the can bus. Can you sugest which one you think would work best?

@@mastermoarman Does the device support RS485 interface?

@@ThatProject no its a CAN bus

The STM32F7 is a beast but the STM ecosystem is horrible to work with in my opinion. TouchGFX is nice but CubeMX is a minefield. Probably fine if you're a full time hardware/software dev and have a grasp of C++ but otherwise an ESP32 diplay with Squareline or GuiSlice is much more friendly, especially the backend business logic in Arduino IDE. Plenty of canbus resources to learn from. Going to STM32 groups is like they're all speaking a different language lol

[1] GUI development varies depending on which tool is used. GUI development is still not easy in an MCU environment. Squareline Square seems to be the best for now. [2] ESP-NOW works well no matter which module is used. The best option for GPIO is to use the SPI interface. Therefore, WT32-SC01 is advantageous. Personally, I recommend WT32-SC01 Plus.

If you prefer an SPI connection, the WT32-SC01, or if you need the ESP32-S2, Makerfabs' ILI9488 seems to be a good choice.

@@ThatProject Thank you, noted your reply.

I connected the ILI9488 and ESP8266 in this video. Please note. ukposts.info/have/v-deo/caejfJ6ZnY93uZs.html

Wow! Are you trying to make your own oscilloscope?? That'll be super cool if it works.

They are from the example of TFT_eSPI. You can find them from it. TFT_graphicstest

Thank you! @@ThatProject

What setting is the problem with WT32-SC01?

No way, there is no secret at all. I just used LovyanGFX as the graphic driver. That's all.

@@ThatProject weird, i'm using the same driver. I just get a white screen when I set it to 80mhz

@@ftab Sorry I have no idea. I think you have to ask about this issue with the manufacturer directly. There may be hardware differences that we are not aware of.

Can't we just connect two devices, Arduino and ESP32-S3, through RX and TX? what are you going to do?

@@ThatProject ​ i am considering buying this one with the parallel TFT to control my arduino which controls stepper motors and my camera (its a focus stacker). I think its better to seperate the UI and the control loops for better performance because i guess if i would drive a tft and control a stepper at the same time with the same microcontroller, then the speed of the motor would be way to slow due to the "slow" rendering speed.

@@ipadize Understood. Is it difficult to configure your system with a single microcontroller? It seems that handling everything with one MCU can be handled faster than connecting two MCUs with UART.

Is it difficult to force the backlight to turn on in code?

Please check this Github. github.com/sowbug/WT32-SC01-Demo It's gonna be a good starting point for your WT32-SC01.

You are right. 16-bit parallel connection is theoretically the fastest. The problem is that when we create our application we are not sending pixel data directly via GPIO. Instead, it completes the connected display through a graphics driver/library, which has different performance depending on how the screen is drawn. What I want to say is that, because we ultimately have a layer called a graphics driver, there is a difference in performance depending on this as well. (Again, if we directly control the GPIO and draw the screen, 16-bit is the fastest)

what you mean? another 3.5 inch LCD controller interface review?
