You have a 0x9302.
I have no idea who makes it. I do not think it is Ilitek even if I invent "ILI9302" in the how_to file.
I have never seen a 0x9302. I do not have a datasheet. I just treat it as a generic 240x320 MIPI-style controller.
Do all the tests, colours, directions work in graphictest_kbv on the Mega2560 ?
Both I and Bodmer specify using the TTGO R32 board. I have a custom WROOM-32 module with soldered Arduino headers. The WROOM-32 is not as reliable as the proper TTGO board. I would not trust an ESP32 module with flying wires on a breadboard even if the readreg sketch "works".
