Hello, I have a new LCD which I believe is an ili4988 (although the vendor says ili9486 and st7796) https://www.aliexpress.us/item/3256803856059047.html I have read somewhere, that I can use an ili9341 spi driver, only by changing the resolution and changing the initialization script. I looked in the waveshare website and github, they don't have anything for the ili9488 Then, I found some arduino code in http://www.lcdwiki.com/3.5inch_SPI_Module_ILI9488_SKU%3AMSP3520 (look for the "3.5 inch SPI Module Package(ILI9488)" link, then find the LCDWIKI_SPI.cpp The initialization sequence is in line 1697: I am currently trying to convert it to a DTS-format init string, so that it fits my ili9341-fb.dts, which I made earlier this year: I am unsure how to start the init line, can someone help me? Then, when I have that init string confirmed, I can use: https://github.com/notro/panel-mipi-dbi/wiki https://blog.csdn.net/CNflysky/article/details/125171176 To switch to the mipi-dbi driver, which would get me DRM (instead of FB)

THANKS TO USER KungFuPancake, who showed me his github repo, where he indicates to use the latest Armbian-edge, and provides the a command byte sequence for the ili9488 https://github.com/KungfuPancake/v0_ips_touch_display?tab=readme-ov-file If you see inverted colors, edit the panel-mipi-dbi-spi.txt and comment the line #command 0x21 before using the mipi-dbi-cmd If you have the cheap chinese clone LCD (see first post), use this DTS (change the gpio codes as needed):
