How to connect this SPI TFT to my Pico W?
Are you using C/C++ or MicroPython? I have used https://github.com/russhughes/st7789_mpy successfully. There are actually two/three libraries related to st7789 displays if this I the one you are using. As already commented, please share a link to the display or some more information about it.

DOOM! on the #emfcamp TiDAL badge
The colour being mangled turns out to be an endian difference between the MPU and the display device, easily determined by looking at the code for the display driver, which byte-swaps everything when drawing into the device, unless it's blitting a buffer, when it assumes it's already swapped. Fixed.

MicroPython display issues on the TTGO T-watch S76G (GPS + LoRa edition)
I ended up making it work but with no help from LilyGo. There's an awesome repo here that includes pre-compiled binaries for the device, libraries for its hardware peripherals, and some code examples

nanoprintf VS callback_printf - a user suggested alternative
2 projects | 16 Aug 2023
- Nanoprintf – The smallest public printf implementation for its feature set

DOOM! on the #emfcamp TiDAL badge
It turns out that DOOM expects a little more POSIX compliance from it's C library than Micropython provides, in particular the printf implementation is lacking many features. The good part is that because I'm building an entirely separate binary application, I can use someone elses printf, and finally, after a lot of pain, it runs!
