how about adding QSPI support for such as ST77903 screen

[qiqiji]

Dear bodmer,

I have been using TFT_eSPI on a few ESP32 projects, and I'm truly impressed by the dedication and quality of your contributions.

Previously, I used the ST7789 display with TFT_eSPI in one of my project, and it worked perfectly. Now, I need to replace the screen with the ST77903, which uses the QSPI interface. However, I noticed that the current TFT_eSPI library does not support it. I found the corresponding driver in the https://github.com/espressif/esp-iot-solution repository and tested it with esp-idf. But without TFT_eSPI, I'm finding it challenging and even not possible to port the UI code from my previous project to the new one. I apologize for taking up your time, but i hope if you have any interest or plans to add QSPI support to TFT_eSPI and that will be great. Thank you.

FYI, driver under esp-idf, i tested works fine ( it cames with lvgl port)

I am interested too.

Lots of products, lilly go and many chinese boards now using QSPI. SO would be a bonus if it was added

I'm also in for the Qspi. The Guition JC3636w518 is a cheap(ish) 1.8" display with SD card, audio in/out build on an ESP32-S3. And assembled in a neat alumim´nium case. Perfekt for esp32 projects.. I really would like tft_espi to support the qspi interface.

➕. The JC3636W518 / ST77916 setup is an excellent device for prototyping and QSPI support in TFT_eSPI would be great.
