Best way to use ST7789 in ESPIDF?
ST7789 is a MIPI DCS chip so you can use HAGL with MIPI DCS HAL. There are a couple of examples and a video or two. Also sorry for blatant self promotion.

Unable to find fast lightweight TFT driver for TTGO T-Display and ESP-IDF
ST7789 is a standard MIPI DCS chip so you could HAGL with the MIPI DCS HAL. In addition to drawing rectangles etc I have used it four couple of proof of concept apps such as video player and old school demo effects.

LameUI - A UI Library for MCUs I have been making for past 6 months
Looks great! Don't worry about hours used or how many people will use it. Think of it as a learning experience. I did something similar with the only goal being to learn the C language.

Ask HN: Nobody interested an open hardware iPod Nano?
So here is the thing: The iPod Nano 7g is from 2012. I've seen many people designing custom PCBs and releasing Kickstarter projects for custom audio players[5] or game handhelds[6]. I know Rockbox (which is great, but its lacks support for Wifi and Bluetooth AFAIK and just does not compete with the UX of iPod's audio book features in my opinion) and iPod Linux. 10 years ago someone even reverse engineered the iPod Nano 6g display[3].
Although I'm not skilled enough in PCB-Design, after some research I found the Lilygo T-Display S3 Pro[4] based on ESP32 S3, which would be the size, but lacks audio and OS. There is also the Mango PI CyberPad[7], which looked interesting, but maybe is already too clunky.
Programming wise, LVGL[8] may be a good framework to develop a modern and efficient UI - at least it looks promising.
So, why is nobody interested in recreating an iPod nano like device? It should be doable with modern tech, but Phones have completely taken over the marked...

Interfacing SPI LCD with Zynq 7020
I'm trying to interface SPI LCD (ILI943) with Zynq 7020 (PYNQ-Z2 board) and LVGL embedded UI libary. And considering between two approaches:
What are some alternatives?
LameUI - A very lame UI library for embedded systems.
TFT_eSPI - Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips
chafa - 📺🗿 Terminal graphics for the 21st century.
LovyanGFX - SPI LCD graphics library for ESP32 (ESP-IDF/ArduinoESP32) / ESP8266 (ArduinoESP8266) / SAMD51(Seeed ArduinoSAMD51)
esp-idf-st7789 - ST7789 Driver for esp-idf
imgui - Dear ImGui: Bloat-free Graphical User interface for C++ with minimal dependencies
microphone-library-for-pico - Capture audio from a microphone on your Raspberry Pi Pico or any RP2040 based board. 🎤
GuiLite - ✔️The smallest header-only GUI library(4 KLOC) for all platforms
hagl_esp_mipi - ESP32 MIPI DCS abstraction layer for the HAGL graphics library
micropython-micro-gui - A lightweight MicroPython GUI library for display drivers based on framebuf, allows input via pushbuttons.
LameUI_simulation - A crappy simulator for my even crappier UI library "LameUI"
slint - Slint is a declarative GUI toolkit to build native user interfaces for Rust, C++, or JavaScript apps.
