So I got my hands on a display from china and I have a schematics and everything.
It’s a touch display with a GT911 driver and a ST7262 LCD Driver in 24Bit parallel mode (I think so at least, see picture)
Does anyone know a library I could use? I’ve looked at LovyanGFX and Arduino_GFX, but I got no clue how I have to use these in 24Bit parallel mode…
Hi, I’m using the same screen and controller. Did you find a sample library?
Hi, I’ve got a example code from the company providing the screen. They used the normal TFT_eSPI library
I haven’t tried it, but what’s wrong with Espressif’s that claim to support that chip?
”The normal TFT_eSPI” library isn’t normal at all; it’s abandoned. It’s had no commits in over a year and doesn’t run in current toolkits. But it’s all just code, so if you’re willing to write/modify/support/maintain it, go nuts.
Hey Folks, i have a similar display (with esp32s3 attached) that works in parallel - RGB565. I got it working with lovyan and arduino_gfx (using config from Guition’s demo code examples) and although both worked they were unsatisfactory, screen glitches/jumping when anything was moving. Almost definately a timing/memory setting but wasted hours trying loads of things.
I found this driver project by chance:- GitHub - rzeldent/esp32-smartdisplay: PlatformIO library LVGL Drivers for Sunton Smart display boards (CYD Cheap Yellow Display). This library supports these boards without any effort. ESP32-2432S024N/R/C, ESP32-2432S028R/C, ESP32-3248S035R/C, ESP32_8048S070N/C
My board isn’t a “Saunton” but guessed it was probably the same/similar.
It works perfectly, has preconfigured config profiles for lots of different displays with built in SOC rock solid display, a couple of LVGL arcs on a background gave 30fps 0%cpu vs 9fps 15%cpu with the other drivers.
Took a few trys to get it setup with LVGL (9.4) with help from Claude AI within VSCode/PlatformIO.
