TFT_eSPI VS u8g2

Bodmer's TFT_eSPI is a graphics library for drawing to various displays, like the ILI9341, which is supported. It can be used with the Arduino IDE to program a Pico to interface with an ILI9341 using SPI, 8 bit parallel or 16 bit parallel interfaces.

For example, the electropeak link you posted showed a TFT LCD with the ILI9341 chip, and if you are using the TFT_eSPI library, this file needs to be configured https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup.h , the default configuration looks correct in this case.

My favorite Arduino compatible graphics library is https://github.com/Bodmer/TFT_eSPI

I was under the impression that since this display uses a ST7789V, I'd be able to use the TFT_eSPI library which has support for this controller with ESP32 board. Is that a correct assumption on my part?

Try the https://github.com/olikraus/u8g2/wiki library.

If you want to stick with the u8g2 library, be sure to check out the u8g2 wiki for some more information. There's a lot of info on the setup page and I find the u8g2 reference especially useful in practice.

Check out the U8G2 library if you're going to work with OLED displays. It's really the best one out there and it does it all, supporting multiple OLED displays with the one library. It also has excellent support for numerous fonts in different sizes.

I have been considering two different methods for achieving this. The first method is the one that Olikraus uses with the u8x8 library, which implements a callback system that handles the hardware abstraction layer. The second method that I have been contemplating is using i2cdev, which allows for sharing the i2c port with other threads.

I use the u8x8 library (https://github.com/olikraus/u8g2/wiki/u8x8reference) for the display. I like this library a lot!

Use u8g2, awesome library, very flexible, works with everything.

Try U8G2. It works with both these OLEDs and many more.

For displays like this, I strongly recommend the U8G2 (https://github.com/olikraus/u8g2) library. It has support for pretty much everything. However, you might need to find/write/tweak your own "hal" later, which is just a couple of simple callback functions that bridge it to the I2C or SPI ports of your MCU.
